Clari vs. Outreach (vs. ZoomInfo): Full 2026 Comparison

Choosing between Clari and Outreach for your revenue operations often comes down to five questions:

• Do you need a platform that tells you what's happening in your pipeline, or one that also moves deals forward?

• Is forecasting accuracy your primary challenge, or is it getting reps to execute consistently?

• Do you want to consolidate multiple tools into one platform, or layer specialized solutions together?

• How important is having accurate, verified contact data and buying signals feeding your revenue workflows?

• Are you looking for AI that surfaces insights, or AI that takes action on those insights?

Here's what we recommend:

Clari is the choice for revenue leaders who need to see everything happening across their pipeline and forecast with precision. Its Revenue Database (RevDB) captures historical snapshots of every deal change, powering AI forecasting that helps teams land within 4% of their sales forecasts. Following its December 2025 merger with Salesloft, Clari is building toward a full revenue system spanning forecasting, deal inspection, sales engagement, and conversation intelligence. The platform manages $5 trillion in revenue for 1,500+ customers, but users consistently note a complex, unintuitive interface and ongoing integration challenges from its acquisition strategy.

Outreach is built for revenue teams that need their reps doing the right things, not just seeing the right data. As the self-described "only end-to-end sales solution", Outreach covers prospecting sequences, deal management, conversation intelligence, forecasting, and customer success in a single platform. Its AI Agents go beyond surfacing insights to researching accounts, generating personalized outreach, and updating CRM fields on their own. Outreach processes $765 billion in pipeline annually, but its breadth creates a real learning curve, and pricing remains opaque with no published tiers.

Both platforms orchestrate revenue workflows. But every workflow depends on the quality of data flowing through it. Incomplete contacts, stale company data, and missed buying signals create blind spots that no amount of forecasting or sequencing can fix. That data foundation is where ZoomInfo enters the picture.

ZoomInfo is an AI GTM platform built on the industry's largest data foundation: 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails. Its GTM Context Graph processes 1.5B+ data points daily, unifying this data with your CRM records, conversation transcripts, and behavioral signals to reveal the full context behind every deal. Teams access this intelligence through GTM Workspace for sellers, GTM Studio for marketers and RevOps, or APIs and MCP inside any third-party tool, including Clari and Outreach themselves.

If accurate data powering every revenue decision sounds like the foundation you're missing, see how ZoomInfo works.

Clari vs. Outreach vs. ZoomInfo at a glance

Revenue visibility vs. revenue execution vs. revenue intelligence

The fundamental difference between these three platforms is what they do when they find a problem in your pipeline.

Clari shows you the problem. Its RevDB captures every change to every deal, surfacing patterns that manual inspection would miss.

When a $200K deal slips from Commit to Best Case, Clari highlights the change in red. When activity on a key account drops, AI health scores flag the risk. The 4-point deal inspection methodology gives managers a structured way to review deals faster, spending less time interrogating reps and more time coaching. RevOps teams report 90% less time spent on forecasting.

Outreach fixes the problem. When deal health declines, Outreach doesn't just flag it.

The Deal Agent analyzes call transcripts and updates CRM fields.

Smart Deal Assist surfaces specific next actions. If a rep needs to re-engage a stalled prospect, they can launch a sequence from the same interface where they spotted the issue. Outreach explicitly contrasts itself against Clari on this point: "Clari shows you pipeline risk, but it doesn't help your team fix it."

ZoomInfo ensures you're working the right problems in the first place. Before you can inspect a deal or execute a sequence, you need to know whether you're targeting the right accounts, reaching the right people, and timing your outreach to actual buying signals.

ZoomInfo's Buyer Intent data, drawn from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings monthly, identifies which companies are actively researching solutions like yours.

The GTM Context Graph then combines that signal data with conversation intelligence, CRM history, and behavioral patterns to explain what's actually driving deal outcomes.

Forecasting approaches differ at the foundation

Forecasting is where Clari built its reputation and where Outreach is making its strongest competitive push.

Clari Forecast is the most mature offering of the three. Built on a proprietary Time Series Data Hub, it snapshots every CRM change over time, creating a historical record that machine learning models use to predict quarter-end outcomes.

Source: Clari

Clari claims 98% forecast accuracy by week two of the quarter. The platform supports subscription, consumption, and hybrid revenue models in a single view, a capability Clari positions as an industry first. Automated rollups eliminate manual aggregation from rep to manager to VP to CRO.

Outreach Forecasting takes a different approach. Rather than building a separate data warehouse, Outreach layers forecast models on top of real-time engagement data. Its AI Projection generates an independent model that accounts for won business, remaining pipeline, and intraquarter deals.

The Scenario Planner runs 10,000 simulations per scenario set to produce probability distributions.

ZoomInfo doesn't compete directly on forecast modeling. Instead, it strengthens the inputs that make any forecast accurate. When 67% of enterprise leaders don't trust their revenue data (a statistic Clari itself cites), the issue isn't the algorithm. It's incomplete CRM data, missing contacts, and buying signals that never made it into the system.

ZoomInfo's Capture and enrichment capabilities fill those gaps, while its intent signals and the GTM Context Graph add predictive context that neither Clari nor Outreach can generate on their own.

Sales engagement is the new battleground

Both Clari and Outreach now offer sales engagement, but they arrived at it from opposite directions.

Outreach started here. Sequences are the product's backbone: structured multi-step campaigns across email, phone, LinkedIn, SMS, and generic tasks.

Reps live inside Outreach daily. Smart Email Assist drafts contextual emails that achieve 10% higher open rates and 2x higher reply rates.

Source: Outreach

The Revenue Agent can identify accounts, source contacts, and generate personalized outreach on its own, with early results showing 15-20% increases in reply rates. This depth in engagement is Outreach's core advantage.

Source: Outreach

Clari acquired its way into engagement. Groove joined in 2023, adding a Salesforce-native sales engagement platform with multi-channel flows and AI-powered email generation.

Source: Clari

Then the Salesloft merger closed in December 2025, bringing one of the category's other leaders into the fold. The vision is compelling: one platform for engagement and forecasting.

The reality is that the joint roadmap is still in development, and the Groove integration (two years after acquisition) remained incomplete before the Salesloft deal closed. Buyers should evaluate where the integration stands today, not where the roadmap promises it will be.

ZoomInfo approaches engagement through intelligence-first execution. GTM Workspace gives sellers an Action Feed of in-market buyers matched to their target criteria, with pre-drafted outreach on every signal. The AI doesn't just know a contact's name and title.

It knows the company is researching your competitor, just hired three VPs, and raised a funding round, and it drafts messaging that addresses those specific conditions.

For teams using Outreach or Salesloft as their sequencing tool, ZoomInfo feeds that intelligence directly into those platforms through native integrations. Thomson Reuters increased closed-won deals by 40% using GTM Workspace.

Conversation intelligence shows three different priorities

All three platforms record and analyze sales conversations, but each emphasizes a different outcome.

Clari Copilot (acquired as Wingman in 2022) focuses on real-time coaching. When a buyer says "too expensive," battlecards surface automatically with pricing responses. Sellers using real-time battlecards see 10% more wins on average.

CRM Suggestions capture meeting insights and create one-click update recommendations. The tool ties into Clari's broader deal inspection workflow, feeding conversation data into forecast models.

Outreach Kaia emphasizes the full meeting lifecycle. Before the call, a Meeting Prep Agent (currently in beta) assembles talking points and attendee context. During the call, Content Cards trigger on competitor names and objections.

After the call, Smart Meeting Assist generates summaries and action items, and the Deal Agent updates CRM fields without rep intervention. Outreach reports that Kaia increases follow-up meeting probability by 36%.

ZoomInfo Chorus prioritizes intelligence extraction. Backed by 14 technology patents, Chorus captures calls, meetings, and emails, then feeds the extracted context into the GTM Context Graph.

The critical difference is Connected Intelligence: when a manager reviews a call recording, they see ZoomInfo's full profile for every participant (contact details, company insights, and buying signals) without switching systems.

That conversation data doesn't just improve the next call. It enriches the intelligence available to every team, in every tool, across every deal.

The data question neither Clari nor Outreach can answer

Here's the gap in both Clari and Outreach: neither platform generates its own contact data, company intelligence, or buying signals. Both depend on what's already in your CRM and what their users create through activity.

Clari's RevDB captures changes to CRM records, but if the records are incomplete or stale, the historical snapshots are incomplete and stale too.

Outreach's AI trains on 3 billion+ signals, but those signals come from engagement within the platform. Neither can tell you that a target company just hired a new VP of Engineering, is actively researching your competitor's product category, or has three decision-makers you haven't identified yet.

ZoomInfo fills this gap. Its data platform covers 500M contacts and 100M companies, verified through a pipeline backed by 300+ human researchers with up to 95% accuracy on first-party data. In a Fortune 500 competitive RFP analyzing 25 million contacts across vendors, an independent consultant concluded that "no other competitor came even close."

This matters practically.

A Clari forecast is only as good as the deals in the pipeline. If your team is missing half the buying committee because no one identified the right contacts, the forecast reflects an incomplete picture.

An Outreach sequence performs only as well as the data behind it. If the email bounces or the phone number is wrong, the most sophisticated AI-drafted message achieves nothing.

ZoomInfo's GTM Context Graph goes further by unifying this third-party intelligence with your first-party CRM data, conversation transcripts, and behavioral signals. The result is a layer that captures why deals move or stall, not just that they did.

As ZoomInfo CPO Dominik Facher wrote: "The CRM recorded the state change. It has no record of why it happened."

Platform consolidation versus best-in-class layering

Both Clari and Outreach are pursuing a consolidation strategy: replace multiple point solutions with one platform.

Clari's approach is acquisition-driven. Wingman for conversation intelligence (2022). Groove for sales engagement (2023). Salesloft for a broader engagement footprint (2025). The promise is a single system for the entire revenue lifecycle.

A customer quote on Clari's pricing page captures the appeal: "I can combine three technology solutions into one single platform." The risk is integration speed. The Groove acquisition took over two years without full integration, and the Salesloft merger's joint roadmap was still in development as of early 2026.

Outreach's approach is organic. Every capability was built in-house: sequences, deal management, Kaia, forecasting, AI agents. This produces a more consistent user experience, but the platform must compete on depth against specialists in each domain.

Outreach calls this out directly, positioning Gong as limited to insights, Clari as limited to visibility, and Salesloft as limited to engagement.

ZoomInfo takes a third path: be the intelligence layer that powers any architecture. Through APIs and MCP, ZoomInfo's data and GTM Context Graph flow into Clari, Outreach, Salesforce, HubSpot, or any custom application.

Teams that choose Clari for forecasting and Outreach for engagement can layer ZoomInfo underneath both. Teams that prefer a consolidated approach can use GTM Workspace and GTM Studio as their primary workspaces, powered by the same intelligence.

CEO Henry Schuck described this as enabling a large financial services firm to build an internal app using ZoomInfo's MCP server: "That's a surface area we would never see before."

This flexibility means ZoomInfo doesn't force a choice between platforms. It makes whichever platform you choose work better.

AI capabilities at different stages of maturity

All three platforms are investing heavily in AI, but their approaches and maturity levels differ.

Clari focuses AI on forecasting and deal inspection. Revenue AI Agents inspect deals around the clock, surfacing risks and recommending actions.

Source: Clari

Smart Deal Summaries aggregate emails, transcripts, and notes into a single view, saving reps 30 minutes per deal on reviews. Usage of AI Deal Summaries increased 572% in six months.

The AI is strongest where Clari's data runs deepest: historical pipeline patterns and forecast modeling.

Outreach is pushing toward autonomous agents. Between December 2024 and February 2026, it shipped AI Prospecting Agents, Research Agent, Deal Agent, Personalization Agent, Revenue Agent, Call Agent, and a Meeting Prep Agent (still in beta).

The Revenue Agent handles the full prospecting workflow on its own.

The Deal Agent applies CRM updates without rep intervention. Several capabilities remain in beta or are labeled "Coming Soon" (Reply Agent, Meeting Prep Agent), so buyers should evaluate current production capabilities against their timeline.

ZoomInfo powers AI with the richest underlying data. The GTM Context Graph doesn't just analyze internal engagement signals. It reasons across ZoomInfo's third-party data, your CRM, conversation intelligence, and behavioral signals to identify patterns behind actual wins.

GTM Workspace's AI agents draft outreach that addresses specific conditions the intelligence layer identified (a competitive evaluation underway, a new executive hire, an intent spike in your product category).

Seismic attributed 39% of active pipeline to ZoomInfo signals and reported 54% productivity gains.

Pricing requires homework for all three

None of these platforms publish straightforward pricing, which makes direct comparison difficult.

Clari directs buyers to a "Get a quote" form without listing per-seat or package prices. The company states there are no platform fees for integrations or support. A free tier exists for Clari Align (five licenses), and Copilot offers a limited free trial.

Outreach operates on a per-user, per-module subscription model with six separate packages: Engage, Call, Meet, Deal, Forecast, and Amplify (AI Agents). Each is priced independently, and the AI Agents tier uses a credit-based consumption model. Voice pricing is published: a Global Minutes Package at $300/month per organization covers 10,000 minutes across 50 countries.

Contracts automatically renew for 12-month periods and are non-cancelable and non-refundable.

ZoomInfo uses a custom-quoted, seat-and-credit-based model across Sales, Marketing, and Operations product lines, each with three tiers (Professional, Advanced, Enterprise).

The permanent free tier, ZoomInfo Lite, provides access to ZoomInfo's database with 10 monthly export credits, plus a separate 7-day free trial of the full platform. API access is included in all relevant plans.

For all three, actual cost depends on team size, modules selected, and negotiation. The meaningful comparison isn't sticker price but total cost of the revenue stack and the results it produces.

Security and compliance are table stakes at this level

Enterprise buyers in regulated industries need verified compliance, and all three platforms meet enterprise requirements.

Clari holds ISO 27001, SOC 2 Type II, ISO 27701, CSA, and GDPR certifications, with a public status page at trust.clari.com.

Outreach carries SOC 2 Type II, ISO 27001, ISO 27701, HIPAA, and CSA STAR, plus ISO 42001 for AI management, making it the first revenue tech company with certified responsible AI.

ZoomInfo maintains ISO 27001, SOC 2 Type II, ISO 27701, TRUSTe GDPR, and TRUSTe CCPA certifications, all renewed annually. As a B2B data company, ZoomInfo is also a registered data broker in California and Vermont, with compliance infrastructure built directly into the data layer.

Clari vs. Outreach vs. ZoomInfo: Which should you choose?

The right platform depends on where your biggest revenue gap is today.

Choose Clari if:

• Forecast accuracy is your most urgent problem

• You need deep pipeline visibility across complex sales organizations

• Your RevOps team wants a dedicated system for revenue inspection and cadences

• You're willing to invest in a platform that's still integrating major acquisitions

• Your team needs native sequences, deal management, and conversation intelligence in one tool

• You're comfortable with a platform that's still shipping key AI capabilities

• Enterprise-grade governance and compliance are non-negotiable

Choose ZoomInfo if:

• You need the most comprehensive, verified B2B data powering every revenue decision

• Your CRM has gaps in contacts, company attributes, or buying signals that undermine forecasting and outreach

• You want intelligence that explains why deals move, not just that they moved

• You need a platform that works inside your existing tools (including Clari and Outreach) through APIs and MCP

• You want native execution through GTM Workspace and GTM Studio, plus the flexibility to power any third-party tool

Start with ZoomInfo Lite for free, or get a full platform trial

Revenue platforms are only as good as the data flowing through them.

Clari can forecast precisely and Outreach can execute relentlessly, but both depend on accurate contacts, timely signals, and complete account intelligence to deliver on their potential.

ZoomInfo provides that foundation, whether your team uses it through GTM Workspace and GTM Studio or feeds it into Clari, Outreach, or any other tool in the stack. In a market where every vendor promises AI-powered revenue growth, the differentiator isn't the algorithm. It's the data the algorithm learns from.
