HubSpot vs Salesforce: A Comprehensive Comparison

Choosing between HubSpot and Salesforce for your CRM comes down to five questions:

• Do you need a platform your team can adopt in weeks, or will you invest months in implementation for deeper customization?

• Is your priority a unified system where marketing, sales, and service share a single database, or do you need the flexibility to configure dozens of workflows across departments?

• Are you a growing company consolidating tools, or a large organization whose processes demand specialized configurations and industry-specific data models?

• How much will you spend on administration, and do you have the staff to manage your CRM at scale?

• Does the quality, completeness, and intelligence of the data flowing into your CRM matter as much as the CRM itself?

That fifth question is where the comparison shifts. Both platforms are strong CRMs. But neither one generates verified contact data, buyer intent signals, or the cross-signal intelligence that tells you why a deal is moving. That intelligence has to come from somewhere.

HubSpot is the CRM for growing companies that want marketing, sales, and service on one platform without hiring a dedicated admin team. Every Hub (Marketing, Sales, Service, Content, Data, Commerce) shares the same contact database, so teams work from a single source of truth. HubSpot serves 288,706 customers across 135+ countries, and its Breeze AI layer runs across all Hubs.

The tradeoff: pricing complexity increases as you scale across Hubs, and customization depth still trails what Salesforce offers at the enterprise level.

Salesforce is the CRM for organizations that need depth, customization, and industry-specific solutions. With 150,000+ customers, it holds the number one CRM market share worldwide. Its Agentforce AI platform, AppExchange marketplace, and 17 industry-specific clouds make it difficult to match in configurability.

The tradeoff: implementations run months instead of weeks, costs compound across clouds and add-ons, and most deployments require dedicated administrators and consulting partners.

Both platforms are strong CRMs. But neither solves the quality, completeness, and intelligence of the data inside them. A CRM is only as good as what it knows about your buyers.

ZoomInfo is an all-in-one AI GTM Platform that integrates with both HubSpot and Salesforce to close the intelligence gap CRMs weren't designed to address. Sales reps walk into every call knowing why the deal is moving, who's championing it, and what's likely to happen next. Marketers describe audiences in plain language and launch plays against accounts that match proven win patterns. Leaders see deal risk before it shows up in CRM stage fields.

That depth comes from the GTM Context Graph, an intelligence layer built on ZoomInfo's B2B data foundation (500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails) processing 1.5B+ data points daily by combining ZoomInfo's data with your CRM records, conversation transcripts, and behavioral signals. Teams reach that intelligence through GTM Workspace for sellers, GTM Studio for marketers and RevOps, or APIs and MCP in any tool or AI agent.

HubSpot vs. Salesforce at a glance

Two different philosophies for the same problem

HubSpot and Salesforce both want to be the system of record for your customer relationships. They approach that goal from opposite directions.

HubSpot was founded in 2006 on the idea that businesses needed a simpler way to attract and convert buyers online. It started as a marketing automation tool, then added a free CRM, then Sales Hub, Service Hub, and eventually six connected Hubs sharing one database.

The philosophy: build everything on one codebase so data flows naturally between teams. The result is a system that works out of the box, with consistent interfaces wherever you are in the platform, but limits how far you can customize it.

Salesforce was founded in 1999 with the idea that enterprise software should live in the cloud. It grew from a CRM into a sprawling platform through internal development and major acquisitions: Tableau for analytics, Slack for collaboration, MuleSoft for integrations, and Informatica for data management.

The philosophy: provide depth and configurability for organizations willing to invest in building exactly what they need. The result is a system that can do nearly anything but requires real effort to set up and maintain.

ZoomInfo sits outside this philosophy tradeoff entirely. Rather than acting as the system of record, it serves as the intelligence layer that feeds both platforms, providing the verified contact data, buyer signals, and contextual insights that make either CRM more effective. Whichever platform your organization runs, ZoomInfo adds what the CRM doesn't generate on its own.

For a direct comparison of how ZoomInfo stacks up against each, see HubSpot vs. ZoomInfo and Salesforce vs. ZoomInfo.

Ease of use vs. depth of customization

HubSpot's interface feels consistent wherever you are in the platform. Whether you're building a marketing email, managing a deal pipeline, or setting up a support ticket workflow, the navigation, terminology, and design patterns stay the same.

That consistency comes from building all Hubs on a single codebase. A marketing manager at a 50-person company can configure HubSpot Marketing Hub without help from IT. For RevOps teams, this translates to lower ticket volume and faster time-to-value, a meaningful factor when evaluating total cost of ownership.

Salesforce's interface has improved with Lightning Experience, but the platform's breadth creates complexity. Each Cloud (Sales, Service, Marketing, Commerce) has its own configuration layer, terminology, and in some cases its own interface patterns. Trailhead offers 1,500+ learning badges and has 6+ million learners, which speaks to both the investment Salesforce has made in education and the learning curve it needs to address.

The practical difference: a 5,000-person enterprise with complex approval workflows, custom objects across multiple business units, and regulatory requirements will find HubSpot's configuration options limiting where Salesforce provides the granular control they need. But the same enterprise should budget for dedicated Salesforce administrators, consulting partners, and an implementation timeline measured in months.

CRM and sales capabilities

Both platforms handle the core CRM job: managing contacts, companies, deals, and pipelines.

HubSpot Sales Hub provides a contact management system with visual deal pipelines, sequences for automated outreach, a meeting scheduler, and a Breeze Prospecting Agent that monitors buying signals and drafts personalized outreach using Apollo as its data provider. The platform scales to 15 million contacts and supports custom objects at the Enterprise tier.

Salesforce Sales Cloud offers deeper sales functionality: Einstein Lead Scoring, AI-generated account plans with SWOT analysis, conversation intelligence with call recording and coaching (available at Enterprise tier), territory planning, commission management, and Revenue Lifecycle Management covering CPQ through subscription billing. Salesforce holds a 4.3/5 rating on G2 across 19,420 reviews, reflecting its deep install base in enterprise sales organizations.

Its Agentforce Sales agents handle prospecting, inbound lead engagement, pipeline management, and automated quoting. The gap narrows every year as HubSpot moves upmarket, but Salesforce retains clear advantages in forecasting, territory management, partner relationship management, and the volume of sales-specific configuration options.

One important note for RevOps teams evaluating AI-powered prospecting: the Breeze Prospecting Agent uses Apollo as its data provider, and Agentforce Sales reaches into Data 360 for contact enrichment, but lists ZoomInfo as its first data partner. Neither CRM generates its own verified B2B contact graph. The data that powers their AI agents has to come from somewhere external.

Marketing automation

HubSpot Marketing Hub is where the company started, and the depth shows. The visual workflow builder handles multi-step nurture sequences triggered by contact behavior, lifecycle stage, and form submissions. The platform includes email marketing with send-time optimization, social media management, landing page builders, audience segmentation, multi-touch attribution, and a growing set of AI tools for content creation and personalization.

HubSpot has also moved early on answer engine optimization, building tools to help content rank in AI-generated search results, an emerging priority for B2B marketing teams as AI-powered search surfaces shift buyer discovery behavior.

Salesforce Marketing Cloud is broader but more fragmented. It spans Marketing Cloud Growth and Advanced (the newer, Data Cloud-native products), Marketing Cloud Engagement for cross-channel B2C journeys, Account Engagement for B2B (formerly Pardot), Personalization, and Marketing Intelligence for analytics. Salesforce reports a 32% increase in marketing ROI for customers using the full platform.

The breadth matters at enterprise scale. But the complexity is real. Different marketing products have different interfaces, different pricing models, and different levels of integration with the core CRM.

ZoomInfo GTM Studio adds a third option for marketing and RevOps teams: an intelligence surface where marketers describe their target audience in plain language, ZoomInfo identifies the matching accounts, and GTM Studio launches plays against them automatically. For B2B teams that want marketing plays connected to verified intent signals rather than CRM-only data, this intelligence layer complements either platform.

Service and support

HubSpot Service Hub provides a help desk workspace, ticketing with SLA management, a knowledge base, customer portal, NPS/CSAT/CES surveys, and a Customer Success Workspace with health scores. The Breeze Customer Agent handles inquiries across chat, email, WhatsApp, and Facebook Messenger, and resolves a high percentage of inquiries autonomously.

Salesforce Service Cloud goes deeper: case management with advanced routing, a service console with AI action plans, enterprise knowledge management, omnichannel engagement, a self-service portal, contact center capabilities with voice integration, and field service management for dispatching technicians. A Forrester TEI study found customers achieved 125% ROI and moved up to 50% of cases to lower-cost digital channels.

HubSpot's service tools are strong and growing. But organizations with contact centers, field service teams, or complex routing requirements will find Salesforce's depth necessary.

The AI race: Breeze vs. Agentforce, and what comes after

Both platforms are making AI their centerpiece. But their approaches differ, and a critical structural gap limits both.

HubSpot's Breeze has three components: Breeze Assistant (a personal AI with CRM context), Breeze Agents (specialized AI for customer service, prospecting, content, and data), and embedded AI features throughout the platform. Breeze runs on HubSpot Credits, included by tier with additional credits available for purchase. The key strength is activation ease: several Breeze features work at free and Starter tiers, and all agents have the full context of the HubSpot CRM. The fundamental constraint: Breeze reasons on HubSpot CRM data, which means it can only act on what your team has already captured.

Salesforce's Agentforce is more ambitious in scope. Built on the Atlas Reasoning Engine, it uses a Reasoning and Acting loop where agents reason about a situation, take action, observe results, and adapt. Pre-built agents cover service, sales development, coaching, shopping, and IT service. Agentforce AI costs $0.10 per action via Flex Credits or $2 per conversation. The Agentforce 1 Sales tier at $550/user/month bundles AI agents with CRM as the flagship product. The Einstein Trust Layer provides zero data retention with LLM partners and PII masking. The constraint is the same as Breeze: Agentforce reasons within the Salesforce data graph, which means it can predict outcomes based on what Salesforce has captured, but it can't detect what's happening outside your CRM.

The shared gap: neither AI platform knows what your buyers are doing before they enter your pipeline. They can't detect which accounts are researching your competitors, which companies recently hired a new VP of Sales, or which contacts just attended a competitor's conference. That intelligence requires an external signal layer.

ZoomInfo's GTM Context Graph operates on a fundamentally different architecture. Rather than reasoning on a single CRM's data, the GTM Context Graph processes 1.5B+ data points daily by fusing ZoomInfo's B2B data with your CRM records, conversation transcripts from Chorus, buyer intent signals from ZoomInfo's proprietary network of 210M IP-to-Organization pairings, and behavioral signals from across the buying journey. The result: an AI that understands not just what happened in your pipeline but why it happened, which accounts are in-market right now, and which signals historically preceded your closed-won deals.

The CFO joined the last call and asked about six-month ROI. The GTM Context Graph connects that to third-party signals showing the company is hiring new VPs and researching your competitor, then surfaces that context to the seller. Seismic attributed 39% of active pipeline to ZoomInfo signals, with their Chief Business Officer noting: "That combination of our internal CRM data, external signals, and AI that's given all that context has helped us craft very specific account- and persona-based messages."

The difference isn't which AI agent is more capable inside its own platform. It's whether the AI has access to the signals that exist outside any single CRM.

Neither CRM solves the data quality problem

Here is the gap both platforms share: a CRM records what you put into it. It doesn't know who your buyers are, how to reach them, or when they're researching solutions. That intelligence has to come from somewhere.

HubSpot offers data enrichment through its Smart CRM, pulling information from emails, calls, and web activity, and through Breeze Intelligence (the Clearbit acquisition), which adds a B2B data enrichment layer. These capabilities are useful but bounded: Breeze Intelligence enriches HubSpot records with company data, but it doesn't give HubSpot sellers a verified direct-dial database or real-time intent signals from accounts that haven't touched your pipeline.

Salesforce provides Data Cloud for unifying customer data across sources, and the Informatica acquisition adds enterprise data management depth. Both are meaningful additions. But Salesforce does not maintain a third-party verified B2B contact database, which is why Salesforce data enrichment typically comes from an external provider. The entire ZoomInfo, Apollo, Cognism, and Lusha ecosystem exists because Salesforce CRM data is necessarily incomplete on its own.

This is why 90% of Zoom's sales team relies on ZoomInfo alongside their CRM. It's why Snowflake feeds 70+ ZoomInfo data fields into their account propensity scoring model. The CRM is the system of record. ZoomInfo is the intelligence that makes the records actionable.

ZoomInfo maintains a verified database of 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business email addresses, continuously refreshed by automated ML and 300+ human researchers achieving up to 95% accuracy on first-party data. In a Fortune 500 competitive evaluation analyzing 25 million contacts across vendors, an independent consultant concluded that "no other competitor came even close."

When a new lead enters your CRM, ZoomInfo automatically enriches the record with job title, department, direct-dial number, company attributes, technographic profile, and org chart position. Smartsheet's Senior Manager of Sales Technology Enablement described it: "ZoomInfo is our one source of truth for account data, and even more so for contact data. There's no other provider in the market that provides you with that level of detail."

ZoomInfo's buyer intent data monitors signals from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings monthly, identifying companies researching topics relevant to your business. Guided Intent, exclusive to ZoomInfo, identifies the topics historically correlated with your deal success rather than requiring manual topic selection.

ZoomInfo fills the intelligence gap in both platforms

ZoomInfo integrates with both HubSpot and Salesforce, and the integration addresses three problems that CRMs create by design.

Incomplete records. CRMs start empty and depend on manual entry, form fills, and email syncs to build contact data. ZoomInfo's B2B database fills the gaps automatically when new leads enter your system, enriching records with verified attributes that sellers and marketers need to act.

No signal layer. CRMs track what your team does (calls logged, emails sent, deals moved). They don't track what your buyers do outside your pipeline. ZoomInfo's intent infrastructure identifies companies actively researching topics correlated with your closed-won patterns, surfacing in-market accounts before they reach your pipeline.

Missing context. A CRM records that a deal moved from Stage 3 to Stage 4. It doesn't record why. The GTM Context Graph fuses CRM data with conversation intelligence, intent signals, and behavioral data to capture the reasoning behind deal movement, then surfaces that context to sellers when it matters.

Teams reach this intelligence through three access points: GTM Workspace surfaces it for sellers inside their daily workflow. GTM Studio gives marketers and RevOps teams a plain-language interface to build audiences, launch plays, and orchestrate campaigns against verified intent signals. The Enterprise API and ZoomInfo MCP expose ZoomInfo data and intelligence to any custom application or AI agent, including Claude and ChatGPT, without custom coding.

BDO Canada's Senior Marketing Intelligence Analyst described the integration: "The plug-and-play aspect of the API means I can integrate it very easily into any process and get information at a moment's notice," reporting an 87% reduction in time spent on data dashboard updates.

Pricing tells you who each platform is built for

HubSpot uses a hybrid model combining per-seat, per-contact, and flat-fee pricing depending on the Hub. Sales Hub starts at $9/seat/month (Starter, annual) and reaches $150/seat/month (Enterprise). Marketing Hub Professional starts at $800/month (annual) with a mandatory $1,500 onboarding fee. The Starter Customer Platform bundles all Hubs at $15/seat/month.

One cost trap to watch: when subscribing to multiple Hubs at different tiers, all Core Seats are billed at the rate of the highest tier. Teams that start with Sales Hub Starter and add Marketing Hub Professional will see their Sales Hub seats repriced upward to match Marketing Hub pricing.

Salesforce uses per-user pricing that escalates across editions. Sales Cloud starts at $25/user/month (Starter Suite) and reaches $550/user/month (Agentforce 1 Sales). Marketing Cloud starts at $1,500/org/month and scales to $30,000/org/month for enterprise engagement. Agentforce AI costs $0.10 per action via Flex Credits. Premier Support adds 30% of net license fees. Most implementations are partner-led, adding cost that doesn't appear in the per-seat number.

ZoomInfo uses consumption-based pricing with a free entry point: ZoomInfo Lite provides access to the B2B database with 10 monthly export credits at no cost. Paid plans are free to start with consumption credits based on usage, scaling with data consumption and use case. For detailed pricing context, see the ZoomInfo pricing guide.

The pricing contrast reflects different buyers. HubSpot's lower entry point attracts growing companies watching their spend. Salesforce's higher cost targets organizations with dedicated procurement budgets. ZoomInfo's consumption-based model reflects the variable nature of data usage, but its CRM integrations mean the investment compounds the value of whichever CRM you're already paying for.

Ecosystem and integrations

HubSpot has grown its App Marketplace to 2,000+ integrations with 2.5 million active installs. The platform provides a REST API covering the full CRM data model and developer tools for building custom integrations. For most mid-market companies, 2,000 integrations cover the standard tech stack.

Salesforce operates on a different scale. AppExchange offers 9,000+ apps with 14+ million installs, and 91% of customers use at least one AppExchange app. MuleSoft adds hundreds of pre-built connectors for complex enterprise integrations. The Trailblazer Community spans 20 million members. For large organizations running dozens of enterprise tools, Salesforce's integration depth is a real advantage.

ZoomInfo takes a different approach. Rather than building a marketplace, it integrates with the platforms go-to-market teams already use: Salesforce, HubSpot, Microsoft Dynamics 365, Snowflake, Outreach, Salesloft, and 120+ others. The Enterprise API and ZoomInfo MCP server extend ZoomInfo's data and intelligence into any custom application or AI agent, including Claude and ChatGPT. ZoomInfo works inside your CRM rather than replacing anything in your stack.

BDO Canada's experience illustrates the integration model: the plug-and-play API connects to any process and delivers data at the moment it's needed, without a new interface to learn or a system migration to manage.

Support and learning resources

HubSpot offers tiered support: community-only for free users, email and chat for Starter, phone support for Professional and Enterprise. HubSpot Academy has certified over 200,000 professionals with free courses and exams. The knowledge base spans 17+ languages.

Salesforce provides three Success Plan tiers: Standard (free, community-based), Premier (30% of net license fees, with 1-hour response time for business-impacting issues), and Signature (custom, with a dedicated Customer Success Manager and 15-minute response for critical issues). Trailhead's 6+ million learners and the Trailblazer Community's 1,300+ local groups in 90 countries form one of the deepest learning ecosystems in enterprise software.

ZoomInfo provides support through its Help Center, ZoomInfo University with role-specific learning paths and certifications, and direct support via phone and web. Enterprise customers receive a dedicated customer success manager. ZoomInfo redesigned its onboarding to a 90-day structured program, producing a 25% improvement in satisfaction and winning Rocketlane's Golden Comet award for implementation excellence.

HubSpot vs. Salesforce vs. ZoomInfo: Which should you choose?

The right answer depends on where you are as a business and what problem you're solving first.

Choose HubSpot if:

• You want marketing, sales, and service on one platform with minimal setup

• Your team is under 500 people and you don't have a dedicated CRM admin

• Time to value matters more than depth of customization

• You're consolidating disconnected tools toward a unified system

• You want a free CRM to start with and room to grow into paid tiers

Choose Salesforce if:

• You need enterprise-grade customization across complex workflows

• You operate in a regulated industry with specific compliance requirements

• You have (or plan to hire) dedicated Salesforce administrators

• You need industry-specific data models and processes

• AppExchange integrations are critical to your tech stack

Use ZoomInfo with either CRM if:

• Your CRM data is incomplete, outdated, or missing key buyer information

• You need to know which accounts are in-market before they contact you

• You want AI that understands why deals move, not just that they moved

• Your sales team spends too much time researching accounts instead of selling

• You want one intelligence layer that works regardless of which CRM you choose

The HubSpot vs. Salesforce decision is about choosing the right system of record for your business. But the quality of what's inside that system determines whether your team spends time selling or searching. ZoomInfo integrates with both platforms, enriches both databases, and provides the buyer intelligence that neither CRM generates on its own. Choose your CRM based on your organizational needs. Then power it with the data and context that makes every team more effective.

Thomson Reuters increased closed-won deals by 40% and achieved 115% average quota attainment each month using ZoomInfo's GTM Workspace alongside their CRM.

HubSpot vs. Salesforce vs. ZoomInfo FAQ

What is the core difference between HubSpot and Salesforce?

HubSpot is a unified CRM built on a single codebase for growing companies that want marketing, sales, and service connected with minimal configuration. All six Hubs share the same contact database, which means marketers, sellers, and service teams work from a single source of truth without data duplication or integration overhead.

Salesforce is a customizable CRM with deeper functionality, a larger app ecosystem of 9,000+ apps, and 17 industry-specific clouds, built for organizations willing to invest in dedicated administration and implementation partners. Its Agentforce platform extends Salesforce into an AI agent layer for building, deploying, and managing autonomous agents across sales, service, marketing, and commerce.

Which CRM is cheaper: HubSpot or Salesforce?

HubSpot has a lower entry point. Its Starter Customer Platform bundles all Hubs at $15/seat/month, while Salesforce Starter Suite begins at $25/user/month. At enterprise tiers, the gap widens: HubSpot Sales Hub Enterprise is $150/seat/month, while Salesforce Sales Cloud ranges from $175 to $550/user/month.

However, HubSpot's mandatory onboarding fees (up to $3,500 for Enterprise) and its mixed-tier seat pricing rule (all seats billed at the highest Hub tier) can push total costs above the listed per-seat price. Salesforce implementations are typically partner-led, adding consulting costs that don't appear in the per-seat number. Both platforms reward early planning around true total cost of ownership rather than list price comparison.

Do I need ZoomInfo if I already have HubSpot or Salesforce?

CRMs store and organize customer data, but they don't generate B2B intelligence. ZoomInfo provides verified contact data, company insights, org charts, technographics, and buyer intent signals that CRMs were not built to maintain.

ZoomInfo integrates with both HubSpot and Salesforce, enriching records and surfacing in-market buyers. Snowflake feeds 70+ ZoomInfo data fields into their account scoring model. Smartsheet calls ZoomInfo their "one source of truth for account data." The CRM is the system of record; ZoomInfo is the intelligence layer that makes those records actionable.

Which platform has better AI capabilities?

HubSpot's Breeze AI is easier to activate and works across all Hubs, with agents for customer service, prospecting, content, and data queries. Breeze runs on HubSpot CRM data, which means agents have deep context within the platform but are bounded by what's already in the system.

Salesforce's Agentforce is more configurable, with autonomous agents, custom agent building via Agent Builder, and the Atlas Reasoning Engine for complex reasoning tasks. Agentforce is similarly bounded: it reasons on Salesforce CRM data and relies on partners for verified contacts and external intent signals.

ZoomInfo's GTM Context Graph provides a different kind of AI: an intelligence layer that understands deal context by fusing CRM data with conversation transcripts, intent signals from 210M IP-to-Organization pairings, and behavioral data, then surfaces that context to sellers in real time. The difference is less about which agent is more capable within its platform and more about whether the AI has access to what's happening outside your CRM.

How long does implementation take for each platform?

HubSpot targets 90 days to meaningful value for most deployments. Salesforce implementations range from weeks for simple Sales Cloud setups to 3-12 months for multi-cloud enterprise deployments, with over 70% led by implementation partners. ZoomInfo deploys in weeks rather than months and integrates with your existing CRM without replacing anything in your stack.

Can I use ZoomInfo with both HubSpot and Salesforce?

Yes. ZoomInfo has native integrations with both platforms and supports Microsoft Dynamics 365, Snowflake, Outreach, Salesloft, and 120+ other tools. The same data and intelligence layer works regardless of your CRM choice. The Enterprise API is included in all relevant plans, and the ZoomInfo MCP server enables ZoomInfo data to flow into any AI agent or custom application.

Which platform is best for a company with under 200 employees?

HubSpot is generally the better CRM choice for companies under 200 employees. Its unified platform, lower entry cost, free CRM tier, and minimal admin requirements make it practical for teams without dedicated CRM staff. The time-to-value advantage compounds quickly when you don't have a Salesforce admin on staff.

Salesforce's depth becomes more valuable as organizational complexity increases, particularly when you need custom objects, territory management, industry-specific data models, or deep AppExchange integrations.

ZoomInfo complements either choice by providing the verified B2B data and buyer intelligence that accelerate pipeline regardless of company size. ZoomInfo Lite offers a permanent free tier with 10 monthly export credits to start.

How do the platforms handle data quality?

HubSpot's Smart CRM offers AI-powered data enrichment from emails, calls, and web activity, plus automatic duplicate detection. Breeze Intelligence (the Clearbit acquisition) adds a B2B data enrichment layer for company attributes.

Salesforce provides Data Cloud for unifying data across sources, with Informatica's data management capabilities added through the 2025 acquisition. Both are useful for unifying internal data sources.

ZoomInfo maintains the largest independently verified B2B database, with 500M contacts verified through a multi-source pipeline backed by 300+ human researchers, achieving up to 95% accuracy on first-party data. In a Fortune 500 competitive evaluation analyzing 25 million contacts, an independent consultant concluded that "no other competitor came even close." This is the data layer that HubSpot and Salesforce customers rely on to fill what their CRM cannot generate on its own.
