6sense vs. HockeyStack (vs. ZoomInfo): Which B2B Revenue Intelligence Platform Fits Your GTM Strategy in 2026?

Choosing between 6sense and HockeyStack for your B2B revenue intelligence often comes down to five questions:

• Do you need a platform that orchestrates campaigns across channels, or one that tells you which campaigns worked?

• Is your priority predicting which accounts are in-market, or proving the ROI of the marketing that brought them there?

• Are you building an ABM program from scratch, or trying to unify analytics across an existing tech stack?

• Do you need AI agents that execute outreach on their own, or an AI analyst that answers ad-hoc revenue questions?

• How important is it that your intelligence layer connects not just to marketing tools, but to your sellers' daily workflow?

In short, here's what we recommend:

6sense is built for B2B marketing and sales teams that want to find anonymous buyers before they raise their hand. Its Signalverse processes over one trillion buying signals daily across intent, web activity, technographics, and CRM data to predict which accounts are in-market. With five consecutive years as a Gartner MQ Leader for ABM Platforms, 6sense excels at account-based orchestration, predictive scoring, and programmatic advertising. However, its enterprise pricing is opaque, implementation requires dedicated RevOps resources, and the platform can overwhelm teams without a clear ABM strategy.

HockeyStack is built for revenue teams that need to prove what's working. Its multi-touch attribution engine tracks the buyer journey from the first anonymous ad impression to closed-won revenue, using cookieless tracking that survives when browsers block third-party cookies. The Odin AI analyst lets users ask plain-English questions about the pipeline and get answers immediately. While HockeyStack's analytics are strong, it starts at $1,400/month, carries a steep learning curve, and its campaign execution is limited compared to full ABM platforms.

Both platforms solve real problems for revenue teams. But they each focus on one side of the equation: 6sense on predicting and orchestrating, HockeyStack on measuring and attributing. Neither provides the foundational layer that makes both prediction and measurement more effective: verified B2B data. That's where ZoomInfo enters.

ZoomInfo is an AI GTM platform built on the largest B2B dataset in the industry: 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails. That data fuels ZoomInfo's GTM Context Graph, an intelligence layer that unifies your CRM records, conversation transcripts, and behavioral signals with the 1.5B+ data points ZoomInfo processes daily. The result: the AI drafting your next email follow-up understands the concern behind the conversation, your next GTM play targets accounts matching your actual win patterns, and your next forecast reflects buying evidence rather than rep optimism. Your team can use this intelligence through the dedicated GTM Workspace for sellers, GTM Studio for marketers, RevOps, and GTM engineers, or APIs and MCP in any front-end.

If broad data, contextual intelligence, and access across tools sound like what your GTM team needs, see ZoomInfo in action.

Relationship to ZoomInfo

Before diving into the comparison, it's worth clarifying how each platform relates to ZoomInfo:

6sense is a direct competitor in the ABM and revenue intelligence space. Both platforms offer intent data, predictive scoring, and campaign orchestration.

The difference is architectural: 6sense built its platform around intent signal processing and predictive models, while ZoomInfo built its around verified B2B data and an intelligence layer (the GTM Context Graph) that connects first-party and third-party data. 6sense lists ZoomInfo as a native integration partner, and many teams use both, but ZoomInfo's data breadth, seller-facing tools, and access via APIs and MCP make it a broader platform.

HockeyStack is a complementary tool.

It focuses on revenue attribution and analytics, not on providing B2B contact data or executing outbound campaigns. HockeyStack tells you which marketing activities drove revenue. ZoomInfo provides the data, signals, and execution layer to act on those insights. Teams can reasonably use both: HockeyStack to measure what worked, ZoomInfo to power what happens next.

6sense vs. HockeyStack vs. ZoomInfo at a glance

Intent data: different sources, different purposes

Both 6sense and ZoomInfo invest heavily in intent data, but the architectures differ.

6sense's Signalverse processes over one trillion buying signals daily from its proprietary B2B Network (keyword tracking across millions of B2B content pages), six third-party intent partners (Bombora, G2, TrustRadius, TechTarget, PeerSpot, and Gartner Digital Markets), website engagement via WebTag, and CRM/MAP activity.

The platform tracks intent in over 40 languages, and Forrester gave it the highest scores possible in accuracy and noise filtering among intent data providers in Q1 2025. The bring-your-own-data model (customers can layer in their existing intent subscriptions) is a real advantage for teams already invested in third-party intent sources.

Source: 6sense

ZoomInfo's Buyer Intent tracks signals from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings sourced monthly.

What sets ZoomInfo apart is Guided Intent, which identifies topics historically correlated with deal success rather than requiring manual topic selection. ZoomInfo was also named a Leader in the Forrester Wave for Intent Data Providers B2B, Q1 2025, receiving the highest possible scores across eight criteria.

Source: ZoomInfo

HockeyStack approaches intent differently.

Rather than operating its own signal network, HockeyStack deanonymizes website traffic at the account level using IP-based identification, integrates G2 buyer intent, and tracks ad impressions (including LinkedIn) to build account-level engagement scores. The intent data serves attribution and scoring, not outbound targeting at scale.

The practical difference: 6sense and ZoomInfo can tell your team which companies are researching solutions like yours across the open web. HockeyStack tells you which companies are engaging with your own properties and content.

Attribution is where HockeyStack pulls ahead

HockeyStack was built for attribution from the ground up, and it shows.

The platform tracks the buyer journey using cookieless fingerprinting technology that doesn't rely on third-party cookies. Because B2B sales cycles often exceed the 90-to-120-day lifespan of a standard cookie, HockeyStack captures touchpoints that cookie-based tools miss. In head-to-head comparisons, HockeyStack claims its cookieless tracking matched up to 40% more closed deals to website activity than cookie-based competitors.

The attribution models are thorough.

Users can apply first-touch, last-touch, linear, time-decay, U-shaped, W-shaped, or custom-weighted models, and toggle between them retroactively without reprocessing data. The Odin AI analyst lets users ask questions like "Which blog posts influenced the most closed-won deals last quarter?" and get structured answers in seconds. HockeyStack can also run lift analysis, comparing treatment and control groups to isolate incremental marketing impact from correlation.

For companies with hybrid Product-Led Growth and sales-led motions, HockeyStack bridges both worlds. It connects in-product user behavior (feature adoption, free-trial engagement) directly to CRM revenue data, showing how product usage patterns influence enterprise upgrades.

6sense provides campaign influence reporting and can attribute pipeline to ABM programs, but its attribution is a supporting feature, not the core product. The focus is on predicting and orchestrating, not measuring.

ZoomInfo's analytics capabilities live in GTM Studio, which provides dashboards tracking engagement, funnel progression, and top-performing segments. While not a dedicated attribution platform, ZoomInfo's analytics benefit from the GTM Context Graph, which connects signals to outcomes across the deal lifecycle.

If proving marketing ROI and understanding which channels drive revenue is the primary need, HockeyStack is the strongest option of the three.

Campaign orchestration favors 6sense

6sense's Intelligent Workflows (launched March 2025) provide a visual, drag-and-drop canvas for building omnichannel ABM campaigns.

Source: 6sense

Decision nodes can reference buying stage, intent keywords, 6QA status, contact engagement grade, and ad engagement. Action nodes push audiences to 6sense's native display ads, LinkedIn, Google Ads, Meta, Salesloft, Outreach, and marketing automation platforms.

The advertising capabilities are native and included with the platform subscription.

6sense operates a proprietary DSP that bids on real-time inventory across major exchanges, including banner, HTML5, native, video, and Connected TV formats. The LinkedIn integration lets customers target by buying stage, a capability unavailable through LinkedIn's native Campaign Manager.

6sense also launched AI Email Agents in August 2025: agents that write, send, follow up, read replies, and route qualified conversations to sales. These agents draw from the Signalverse and CRM data to personalize every message.

HockeyStack's orchestration is limited by comparison. It can sync audiences to ad platforms and trigger workflows based on intent scores, but it doesn't operate a native ad network or send emails. Its strength is telling you what to do with your budget, not executing the campaigns.

ZoomInfo's orchestration lives in GTM Studio, which combines audience building, multi-channel campaign execution (email, calls, ads, direct mail), and waterfall enrichment from 25+ data sources. ZoomInfo also operates a native DSP for display advertising and offers signal-triggered workflows that route accounts to sellers in GTM Workspace. Expansion plays that previously took weeks now launch in 30 minutes.

For teams that need to build and run ABM campaigns from a single platform, 6sense and ZoomInfo both deliver. HockeyStack informs campaign strategy but relies on other tools to execute it.

The data foundation determines everything else

This is where the comparison exposes a structural difference.

6sense maintains a contact and company database of 415M+ profiles and 65M+ companies.

Its Sales Intelligence product offers over 390 million people profiles with email and phone data, accessible through the web app, Chrome extension, and CRM widgets. The data is credit-gated: one credit unlocks one person's email or phone data, and credits don't roll over between periods. A free tier offers 50 credits/month but excludes intent data, predictive scoring, and CRM integration.

HockeyStack has no proprietary contact database. It's an analytics and intelligence layer, not a data provider. If you need contact information, org charts, or verified phone numbers to act on the insights HockeyStack surfaces, you need another tool.

ZoomInfo's data is the largest of the three: 500M contacts, 100M companies, 135M+ verified phone numbers, 120M direct dials, and 200M+ verified business emails. The verification infrastructure combines automated ML scanning of 28 million site domains daily, third-party data covering 95 million businesses, a community of 200,000+ ZoomInfo Lite users who share data back, and 300+ human researchers. In a Fortune 500 competitive RFP analyzing 25 million contacts across vendors, an independent consultant concluded that "no other competitor came even close."

Why does data breadth matter for intent and attribution platforms? Because signals without contacts are insights without action. Knowing an account is in the Decision stage means nothing if you can't reach the buying committee. Knowing a blog post influenced a deal is interesting but useless unless you can identify and contact the people who read it.

AI approaches reflect different philosophies

Each platform uses AI, but for different ends.

6sense launched RevvyAI in November 2025 as a conversational command center.

Users can configure signals, build audiences, launch campaigns, and generate reports through natural language. Three pre-built agents (6QA Analyst, Ad Campaign Companion, Keyword Advisor) handle specific tasks on their own. The AI Email Agents handle end-to-end outbound: writing, sending, following up, reading replies, and routing qualified conversations. The AI draws from the Signalverse, so messages are timed to observed buying behavior rather than fixed cadences.

Source: 6sense

HockeyStack's AI lives in Odin, a conversational analyst powered by a proprietary LLM called NEX-LM.

Odin does one job well: answering business questions about pipeline and attribution. Ask "Why are MQLs down this quarter?" and Odin doesn't just show the metric. It explains the contributing factors and recommends actions. It also works in Slack, so teams can query data without logging into a dashboard. HockeyStack reports an 89% autonomy/accuracy rate for Odin's automated reporting.

ZoomInfo's AI is embedded throughout the GTM Context Graph, which processes 1.5B+ data points daily.

In GTM Workspace, AI agents research accounts, draft outreach, monitor signals, and update CRM fields. The AI doesn't just know that a CFO joined the last call. It identifies that executive sponsorship entering at this stage, combined with specific questions asked, matches patterns behind closed-won deals. In GTM Studio, users describe audiences in natural language and the AI builds, enriches, and activates them.

The distinction: 6sense's AI executes marketing and outbound campaigns. HockeyStack's AI analyzes and explains revenue data. ZoomInfo's AI operates across the deal lifecycle and powers action at every surface.

Seller experience sets ZoomInfo apart

Neither 6sense nor HockeyStack was designed as a primary tool for individual sellers.

6sense's Sales Intelligence includes an account dashboard, discovery filters, Persona MAP, and a Chrome extension. Sellers can see which accounts are in-market and access AI-generated insights. But the product's center of gravity is marketing. The ABM orchestration, predictive models, and advertising capabilities are where 6sense invests most.

Source: 6sense

HockeyStack provides account scoring and intent alerts that sales teams can use, and the Nova AI assistant offers next-best-action suggestions. But it's an analytics platform at its core. Sellers benefit from the intelligence, but they don't live in HockeyStack the way they live in a CRM or prospecting tool.

ZoomInfo's GTM Workspace was built as a seller's daily environment. It replaces the need to toggle between prospecting tools, CRMs, and engagement platforms by bringing the complete book of business, AI-drafted outreach, buying group intelligence, and deal execution into one place.

Seismic's sales team reported 54% productivity gains and 11.5 hours saved per week. Thomson Reuters increased closed-won deals by 40%.

For revenue teams where sales and marketing need to operate from shared intelligence, ZoomInfo's architecture serves both sides. 6sense tilts toward marketing. HockeyStack tilts toward analytics.

Pricing: transparency varies widely

6sense does not publish pricing. All paid plans require a sales conversation.

The credit system governs contact data access: one credit unlocks one contact's information, and credits don't carry over. The free tier provides 50 credits/month but excludes core ABM features. The full suite (predictive models, Intelligent Workflows, advertising, AI Email Agents) is an enterprise-level investment. Advertising is included with platform subscriptions but carries 15-18% data/service fees on campaign spend.

Source: 6sense

HockeyStack doesn't publish exact prices either, but publicly references two tiers: GTM Intelligence (reporting, Odin, scoring, workflows) and GTM Execution (everything in Intelligence plus all AI agents and 250,000 credits). Industry estimates place the starting price around $1,400/month, scaling with company size and data volume. There's no free tier for the core platform.

Source: HockeyStack

ZoomInfo uses custom-quoted, seat-and-credit-based pricing across three product lines (Sales, Marketing, Operations), each with multiple tiers.

The key differentiator is ZoomInfo Lite: a permanent free tier (not a trial) with access to the B2B database, 10 monthly export credits, individual and company searches, the Chrome extension, and WebSights Lite. A separate 7-day free trial provides access to core paid features.

Source: ZoomInfo

None of these platforms are cheap. All three target mid-market and enterprise B2B companies with complex sales cycles.

The real cost comparison requires evaluating total stack cost: a team using HockeyStack still needs a data provider and an execution platform. A team using 6sense may still need a dedicated attribution tool and supplementary contact data. ZoomInfo combines data, intelligence, and execution, with API and MCP access included in all relevant plans.

Implementation and learning curve

6sense requires significant setup.

The onboarding process involves role-specific tracks for administrators, marketing, sales, and AI Email, spanning data standardization, predictive model taxonomy, credit distribution, and SSO configuration. Predictive models are trained on each customer's historical won/lost data, which means time to value depends on CRM data quality.

Beta customers of Intelligent Workflows reported saving 5-10 hours per week in manual oversight that the platform previously required, which tells you something about the effort before that feature launched.

HockeyStack markets itself as no-code and quick to implement.

Installing the tracking script is straightforward, and CRM integrations use one-click OAuth. But users consistently report a steep learning curve. Building custom attribution models, defining funnel stages, and structuring reports takes weeks to months. The platform's flexibility is both its strength and its challenge: there's no rigid out-of-the-box model, so teams must build their own measurement framework.

ZoomInfo offers the broadest product surface, which means onboarding scales with what you use.

The company redesigned onboarding from 30 to 90 days across planning, implementation, education, and adoption phases, producing a 25% improvement in customer satisfaction scores. GTM Workspace "deploys in weeks, not months". ZoomInfo University provides role-specific learning paths and certifications. And ZoomInfo Lite lets teams start using core search and export features immediately, for free.

Integration ecosystems

6sense integrates with the major CRM, MAP, and SEP platforms: Salesforce, HubSpot, Dynamics for CRM; Marketo, Eloqua, Pardot, HubSpot for MAP; Salesloft, Outreach, Gong for SEP.

It also integrates six third-party intent providers and advertising platforms (LinkedIn, Meta, Google, The Trade Desk). Forrester noted that other tech platforms prioritize integration with 6sense, an ecosystem advantage. Data can be exported via SFTP, S3, or Snowflake.

HockeyStack connects to CRMs (Salesforce, HubSpot, Pipedrive, Close), ad platforms (LinkedIn, Google, Facebook), marketing automation (HubSpot, ActiveCampaign, Customer.io), intent providers (G2, Vector.co, Clearbit), and tools like Slack, Calendly, Drift, and Gong.

The platform supports webhooks for custom data ingestion and outgoing triggers, plus a REST API. For an analytics tool, the integration depth is solid, though narrower than what the orchestration-focused platforms offer.

ZoomInfo's App Marketplace lists 120+ integrations across CRM, MAP, SEP, data warehouse, communications, and ATS categories.

Cloud Partners enable direct data ingestion into AWS, Google Cloud, Snowflake, and Databricks. The Enterprise API covers search, enrich, AI intelligence, audience management, and engagement data. The MCP server connects AI models directly to ZoomInfo data, currently supporting Claude and ChatGPT. API access is included in all relevant plans, not gated behind enterprise tiers.

Security and compliance

All three platforms maintain enterprise-grade security certifications:

6sense holds ISO/IEC 42001:2023 (AI governance), ISO/IEC 27001:2022, SOC 2 Type II, CSA STAR for AI, TRUSTe GDPR and CCPA validations, and EU-U.S., UK, and Swiss Data Privacy Framework certifications. The AI governance certification, among the first in B2B software, is notable for teams evaluating AI-heavy platforms.

HockeyStack holds SOC 2 Type II, ISO 27001, and complies with GDPR, CCPA, and CPRA. Its cookieless tracking reduces PII exposure by design, and its AI models operate under strict data isolation (customer data is never used to train shared models).

ZoomInfo maintains ISO 27001, ISO 27701 (privacy management), SOC 2 Type II, TRUSTe GDPR, and TRUSTe CCPA certifications, all renewed annually. ZoomInfo is a registered data broker in California and Vermont, and its compliance infrastructure is built into the data layer. For regulated industries, ZoomInfo's privacy certifications (particularly ISO 27701) provide added assurance.

The B2B revenue intelligence market is converging. Intent platforms are adding attribution. Attribution platforms are adding intent. Everyone is adding AI agents. But the factor that determines whether any of these capabilities work is data: how broad it is, how accurate it is, and how accessible it is across every tool your team uses.

6sense and HockeyStack each solve a specific piece of the puzzle well. ZoomInfo connects those pieces with the data to reach buyers, the intelligence to understand deals, and the access to power action across any workflow.
