Clari vs. People.ai Comparison

If you are comparing Clari vs. People.ai, you are asking one question: how do we stop guessing about our pipeline and start knowing?

Both platforms replace spreadsheet forecasting with AI-powered revenue intelligence. Both capture sales activity automatically and flag deal risks before they become missed quarters. But the differences in how they work, and what they leave out, matter more than most comparisons admit.

The real questions you should ask:

• Do you need a platform that orchestrates seller workflows and consolidates forecasting with sales engagement, or one that answers specific revenue questions on demand from a deep activity graph?

• Is your priority the most mature forecasting engine in the market, or an activity-grounded intelligence layer that reduces dependence on rep self-reports?

• How important is it that your revenue intelligence rests on verified contact and company data, not just the activity your reps happen to log?

• Are you willing to wait months for full platform integration as two major vendors unify after a merger, or do you need results in two to four weeks?

• Does your team need AI that acts on deals, or AI that explains deals?

In short, here is what we recommend:

Clari serves enterprise revenue teams that want to consolidate forecasting, deal inspection, sales engagement, and conversation intelligence in one platform. After its December 2025 merger with Salesloft, Clari calls itself a Predictive Revenue System that ingests more than 10 billion revenue interactions and 1 trillion data signals. However, users consistently report an unintuitive interface, and the Salesloft integration remains a work in progress, with the joint roadmap still in development as of early 2026.

People.ai serves enterprise sales organizations that want to understand what is actually happening in their deals based on engagement data rather than rep self-reports. The platform (rebranding to Backstory in 2026) automatically captures every email, call, and meeting and matches each to accounts and opportunities, then uses AI to answer specific pipeline questions. But People.ai's high cost and long full-deployment timelines can delay results, and the platform does not publish pricing.

Both platforms make sense of revenue data inside your CRM and communication tools. But neither generates the data that revenue intelligence depends on: verified contacts, direct dials, org charts, company intelligence, and buying signals. That is the layer underneath, and it determines whether your AI has complete information or is working from gaps.

ZoomInfo is an all-in-one AI GTM Platform built on 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails. Its GTM Context Graph processes 1.5B+ data points daily, connecting this data with your CRM records, conversation transcripts, and behavioral signals to show the full context of your accounts. That context lets AI show not just what happened, but why, and what to do next. Your team accesses this through GTM Workspace for sellers, GTM Studio for marketers and RevOps, or through Enterprise API and ZoomInfo MCP in any other front-end. For teams evaluating revenue intelligence platforms, ZoomInfo addresses a question the others do not: where does the data come from, and is it complete?

Clari vs. People.ai vs. ZoomInfo at a glance

Forecasting: Clari's deepest strength, People.ai's newest bet

Forecasting is where Clari has invested the most and where the gap between these platforms is clearest.

Clari built its reputation on replacing manual forecasting. Its Revenue Database (RevDB) captures historical snapshots of every pipeline change, and the forecasting engine uses this time-series data to project outcomes. The platform reports 98% forecast accuracy by week two of the quarter and supports multiple revenue models -- subscription, consumption, and hybrid. RevOps teams using Clari report 90% less time spent on forecasting.

The forecasting workflow is mature. Managers get automated forecast roll-ups from rep to VP to CRO, scenario modeling, and AI deal-risk detection that flags slipping deals before they show up in stage changes. For organizations running layered forecasting across business units and revenue models, this depth is hard to match. 75,000+ teams trust Clari Forecast, making it the most established standalone forecasting product in the revenue intelligence category.

People.ai launched its AI-native forecasting solution in October 2025. Its approach differs from Clari's: rather than building a forecasting engine from historical pipeline snapshots, People.ai grounds forecasts in automatically captured activity data.

The logic is straightforward. If the platform knows every email, call, and meeting on a deal, it can assess deal health more accurately than a system relying on CRM stage updates that reps may or may not keep current. People.ai reports 20-30% improvement in forecast accuracy from customers using the activity-grounded approach. The platform's Top Stories feature aggregates forecast risks across the pipeline, and Forecast Waterfall Charts show how forecasts changed over time. This solution is newer and less proven at scale than Clari's, but the nine-year activity dataset underlying it -- billions of touchpoints, 160M+ business contacts -- represents a differentiated data moat for the forecast model.

ZoomInfo approaches forecasting from a different angle. Rather than building a standalone forecasting module, ZoomInfo enriches the signals that feed forecasting decisions. The GTM Context Graph captures why deals move or stall by combining CRM data with conversation intelligence from Chorus, intent signals, and behavioral data. When a target account's CFO joins a call and asks about ROI, the Context Graph does not just record the stage change. It identifies the pattern. That intelligence flows into GTM Workspace, where sellers see deal health signals alongside verified account data and buying committee maps.

This is why ZoomInfo integrates naturally with both forecasting platforms: ZoomInfo provides the data accuracy layer that determines whether Clari or People.ai is reasoning on complete information. Thomson Reuters increased closed-won deals by 40% using ZoomInfo's GTM Workspace.

Activity capture and CRM data quality

People.ai is built around this problem. The Backstory Revenue Answers Platform automatically captures every email, call, and meeting across a customer's GTM tools and matches each interaction to the right Salesforce, Dynamics, or Oracle account and opportunity. This is not a simple activity-sync -- People.ai holds 49 patents on its activity-to-deal matching accuracy, and the platform simultaneously supports Salesforce, Microsoft Dynamics, and Oracle in one deployment, which is unusual at enterprise scale.

The result: CRM records reflect what actually happened, not what reps remembered to log. Ping Identity noted that People.ai is "fully integrated with our CRM and took just a few clicks to set up." Five9 saved 1,000+ hours annually with People.ai handling automated activity logging. Forcepoint reduced manual CRM entry time by 75-85%.

Most implementations go live in 2-4 weeks. People.ai also analyzes two years of historical activity on day one, which means teams get immediate context on existing deals rather than starting from zero.

Clari addresses CRM data quality through its Capture product, which auto-logs seller activity into the CRM as the foundational layer for the rest of the platform. Clari's approach is integrated: Capture feeds Inspect (opportunity management), which feeds Forecast, which feeds the broader Revenue Orchestration Platform. The tradeoff is that each module adds implementation surface area.

ZoomInfo approaches CRM data quality from the third-party side. Where People.ai and Clari capture what your reps do, ZoomInfo enriches your CRM with verified contact data, company firmographics, org charts, and technographics that your team never had. ZoomInfo Operations handles this waterfall enrichment, drawing from approximately 60 verified data vendors. The GTM Context Graph then fuses this third-party foundation with the first-party activity layer -- connecting what your reps said with who the buyer actually is, who else is on the buying committee, and what signals suggest they are ready to move.

The practical difference: People.ai and Clari make it easier to see what happened with contacts already in your CRM. ZoomInfo makes sure those contacts are complete, accurate, and connected to the right buying signals in the first place.

The data foundation gap

This is the structural difference that separates ZoomInfo from both Clari and People.ai.

Clari and People.ai are intelligence layers that sit on top of your CRM. They capture what your reps do, analyze it, and surface insights. This is valuable. But the quality of those insights depends entirely on what is already in your CRM and your reps' outboxes.

Consider a common scenario: a deal is stuck because the economic buyer has not been engaged. Clari's Inspect will show low activity on the deal. People.ai's Backstory will flag the missing stakeholder in the MEDDPICC scorecard. But neither platform can tell you who that economic buyer is, what their direct phone number is, or whether the company is actively researching solutions right now.

ZoomInfo can. The platform provides 120M direct-dial phone numbers, 200M+ verified business emails, department org charts with decision-makers identified, and Buyer Intent signals tracking research activity across 210 million IP-to-Organization pairings. When a target company starts researching your category, ZoomInfo detects it. When you need the CFO's direct line, ZoomInfo has it.

This is why ZoomInfo integrates natively with both Clari and People.ai. Clari lists ZoomInfo as an integration partner for data enrichment. People.ai lists ZoomInfo with Relationship Maps visualization. Both platforms recognize they need a data foundation underneath them, and ZoomInfo is the one most enterprise teams choose.

But ZoomInfo is not just a data provider feeding other tools. The GTM Context Graph fuses ZoomInfo's verified B2B data with your CRM records, conversation intelligence from Chorus, and behavioral signals, then connects all of it into one picture. A CRM records that a deal moved forward. Chorus captures what the VP said on the call. Intent data shows the company is hiring three new VPs and researching competitors. The Context Graph connects these signals to show why the deal is moving and what to do next.

Sales engagement and workflow execution

This is where Clari, People.ai, and ZoomInfo diverge most sharply on scope.

Clari now covers sales engagement through Groove (acquired) and, following the December 2025 merger with Salesloft, the full Salesloft cadence and engagement stack. The combined Clari + Salesloft platform is positioned as a Predictive Revenue System. The strategic value is clear: one vendor for forecasting, deal inspection, conversation intelligence, and sales engagement. The practical consideration is that the integration is still in progress -- the joint roadmap was still in development as of early 2026, and teams evaluating this path should confirm which Salesloft capabilities are fully unified with Clari before committing.

People.ai is explicitly not built for rep productivity or outbound sequencing. The platform is designed for revenue leaders -- CROs, VPs of Sales, RevOps -- not individual SDRs or AEs running sequences. TrustRadius reviewers note that People.ai does not have cadence or sequence functionality and is a complement to engagement vendors, not a replacement. If your priority is seller workflow and outbound execution, People.ai requires a separate engagement tool alongside it.

ZoomInfo covers sales engagement through GTM Workspace, where AI agents handle account research, outreach drafting, CRM updates, and signal monitoring in one interface. ZoomInfo also has a partnership with Salesloft that syncs ZoomInfo Buying Signals to Salesloft Rhythm for AI-prioritized engagement, connecting intent data directly to sales sequences. Seismic's sales team boosted productivity by 54% and saved 11.5 hours per week using GTM Workspace.

For RevOps teams evaluating vendor consolidation, the question is: does Clari's post-merger platform reduce your stack count, or does it require running Clari and a parallel integration for twelve to eighteen months while the roadmap matures?

Conversation intelligence and call coaching

Clari Copilot is Clari's conversation intelligence and coaching product -- from the Wingman acquisition -- and provides real-time in-call analysis, deal momentum signals, and coaching dashboards. A key differentiator: real-time battlecards during live calls, not just post-call analysis. Clari Copilot's CI signals feed directly into Clari Forecast for unified deal context, which is a stronger integration than most standalone CI vendors offer.

People.ai does not include native conversation intelligence. The platform captures activity from Zoom, Teams, and other meeting tools, but it is not a call-recording or CI platform. People.ai frames this deliberately: "Call recording tools capture transcripts of what was said on calls. Backstory captures everything -- calls, emails, meetings, and chat -- matches it all to the right deals." The positioning is breadth of activity capture over call-recording depth.

ZoomInfo Chorus is a standalone conversation intelligence product that feeds into the GTM Context Graph. This is a meaningful architectural difference: Chorus transcripts do not sit in a silo. They become part of the unified reasoning layer that connects what was said in meetings with verified contact data, intent signals, and deal history. When CI signals are part of the Context Graph, AI agents in GTM Workspace can reason across the full picture -- not just what happened on one call. The broader question of how AI agents consume and act on go-to-market data is explored in depth in the post on fueling AI agents with go-to-market intelligence.

User experience and implementation

Enterprise platforms live or die by adoption. Features do not matter if teams will not use them.

Clari receives mixed feedback on usability. Users praise it for real-time insights, but others consistently report that the interface is "not very intuitive and feels clunky." Some users maintain separate spreadsheets to track deals alongside Clari. The platform recommends persona-based training over module-by-module approaches, and new users typically need weeks to become proficient. Initial setup can be complex, and users often need to go through support or Customer Success for configuration changes.

People.ai faces similar usability challenges. Multiple reviewers note the user interface was "not very intuitive for the end user" and requires additional logins. The mobile app is underdeveloped. However, People.ai's PeopleGlass interface is a bright spot: a spreadsheet-like view for CRM data that most users find familiar and fast. Most implementations go live in 2-4 weeks, though full deployment can run longer. The Backstory rebrand (in progress) means some product URLs and documentation are currently in transition.

ZoomInfo has invested in onboarding, redesigning its program across planning, technical implementation, education, and adoption phases. This produced a 25% improvement in customer satisfaction scores. ZoomInfo University provides role-specific learning paths, certifications, and live webinars. GTM Workspace is designed to deploy in weeks. For teams that want to start before committing, ZoomInfo Lite provides permanent free access to the B2B database with 10 monthly export credits and no time limit.

Pricing comparison

None of these platforms publish specific pricing, which is standard for enterprise revenue software.

Clari directs buyers to a "Get a quote" form rather than listing prices. The company states there are no platform fees for integrations or ongoing support. Clari offers two free entry points: a Copilot free trial with limited duration and five free Align licenses with no time limit.

People.ai uses subscription-based pricing with fees specified in individual order forms. Fees are based on subscriptions purchased, not actual usage. Subscriptions automatically renew with up to 5% increases unless cancelled 30 days before term end. Multiple users cite high cost as a barrier. Third-party data from Vendr shows a median of approximately $23,100 per year based on 47 purchases, though this is not officially published pricing.

ZoomInfo is free to start with consumption credits based on usage. The practical advantage for evaluating teams: ZoomInfo Lite is a permanent free tier with no credit card or time limit, plus a 7-day free trial of the full platform. Neither Clari nor People.ai offers comparable free access to their core products.

Integrations and ecosystem

All three platforms exist within a broader GTM stack.

Clari maintains native integrations across communication tools (Slack, Google Workspace, Microsoft Teams, Zoom, Webex), CRM platforms (Salesforce, Pipedrive, HubSpot), data providers (ZoomInfo, Clearbit, 6Sense), and conversation intelligence tools (Gong, Chorus). The Clari Platform API enables data extraction for forecast calls, adjustments, and quota history. Clari's joint Salesloft Forecasting Execution MCP Server connects the combined platform to external AI tools.

People.ai integrates natively with Salesforce, Microsoft Dynamics, and Oracle Fusion Sales for CRM; Gmail, Google Calendar, Microsoft 365, and LinkedIn for communication; and ZoomInfo, 6sense, and Clearbit for data intelligence. The MCP integration (announced February 2026) connects to Claude, Copilot, and ChatGPT for natural language queries against deal data. Data warehouse support includes Snowflake, Tableau, PowerBI, AWS, and Azure.

ZoomInfo's App Marketplace lists 120+ partner integrations. Beyond standard CRM and marketing automation connectors, ZoomInfo's Enterprise API provides programmatic access to its data and intelligence, and the ZoomInfo MCP server connects AI models directly to ZoomInfo's B2B data. API access is included in all relevant plans, and Cloud Partners enable direct data ingestion into AWS, Google Cloud, Snowflake, and Databricks. The same intelligence powering ZoomInfo's own products is accessible in any tool.

Clari vs. People.ai vs. ZoomInfo: Which should you choose?

The right platform depends on which problem is most urgent for your revenue team.

Choose Clari if:

• Forecast accuracy is your top priority and you need the most mature forecasting engine available

• You want to consolidate sales engagement, conversation intelligence, and pipeline management into one vendor, and you are comfortable with an eighteen-month integration timeline as Clari unifies its acquisitions

• You have a dedicated RevOps team that can manage a complex implementation and ongoing configuration

• Your sales process requires layered forecasting across multiple revenue models and business units

• You want real-time CI battlecards during live calls alongside forecast roll-up in a single platform

Choose People.ai if:

• Deal qualification and methodology enforcement (MEDDPICC, BANT) are your primary challenges

• You need accurate activity capture and automatic CRM data enrichment from engagement history across multiple CRM systems simultaneously

• Relationship mapping based on actual buyer engagement patterns matters more than static org charts

• Your team's biggest pain point is forecast calls spent chasing reps for updates instead of coaching deals

• You are a large enterprise with multi-stakeholder deals where understanding buying committees based on actual engagement (not just org charts) is critical

Choose ZoomInfo if:

• Your revenue intelligence is limited by incomplete contact data, missing org charts, or lack of buyer intent signals

• You need a data foundation that powers prospecting, pipeline generation, and deal intelligence in one platform

• You want AI that acts on deals -- drafting outreach, surfacing buying signals, identifying hidden stakeholders -- rather than just reporting on them

• You want your data and intelligence available in any tool, whether through ZoomInfo's native products, APIs, or MCP connections to AI agents

• You value an accessible entry point: a permanent free tier and a trial before committing

Start with ZoomInfo free, or explore the full platform to see the intelligence layer in action.

Clari and People.ai have made revenue forecasting and deal intelligence far more accessible than the spreadsheet era allowed. But the next step is not just understanding what happened in your pipeline. It is having the complete data, buying signals, and context to know what should happen next, and the execution tools to make it happen. That is the layer ZoomInfo provides, whether as the foundation underneath your existing tools or as the platform you run your entire GTM motion on. For teams thinking through how to build that execution layer, the best AI sales tools for GTM strategy covers how to evaluate and assemble the right stack for your revenue motion.

What is the main difference between Clari, People.ai, and ZoomInfo?

Clari is a revenue orchestration platform focused on forecasting, deal inspection, and sales engagement (now including Salesloft post-December 2025 merger). People.ai (rebranding to Backstory) is a revenue answers platform focused on automatic activity capture, deal qualification, and answering specific pipeline questions from a nine-year activity graph. ZoomInfo is an all-in-one AI GTM Platform that provides the foundational data layer (500M contacts, 100M companies, intent signals) along with GTM Workspace for sellers, GTM Studio for marketers and RevOps, and APIs and MCP access for any AI agent or workflow.

Which platform has the best forecasting capabilities?

Clari has the most mature forecasting engine, with reports of 98% forecast accuracy by week two of the quarter and support for subscription, consumption, and hybrid revenue models. 75,000+ teams use Clari Forecast. People.ai launched its AI-native forecasting solution in October 2025, grounding forecasts in automatically captured activity data rather than historical pipeline snapshots and reporting 20-30% improvement in forecast accuracy. ZoomInfo enriches forecasting decisions through its GTM Context Graph and buying signals rather than providing a standalone forecasting module.

Do Clari and People.ai integrate with ZoomInfo?

Yes. Both Clari and People.ai list ZoomInfo as a native integration partner. Clari integrates with ZoomInfo for data enrichment. People.ai integrates with ZoomInfo for data intelligence and Relationship Maps visualization. ZoomInfo's MCP server also makes it accessible to any AI agent or tool the team uses. Many enterprise teams run all three: ZoomInfo as the data and signals foundation, Clari or People.ai as the revenue intelligence and forecasting layer.

Which platform is best for improving CRM data quality?

All three address CRM data quality, but differently. Clari Capture and People.ai automatically log sales activities (emails, calls, meetings) to CRM, eliminating manual entry. People.ai captured and matched activity that saved Five9 1,000+ hours annually, and reduced manual CRM entry time by 75-85% at Forcepoint. ZoomInfo approaches the problem from the data side, enriching CRM records with verified contacts, firmographics, org charts, and technographics -- the records that often do not exist in your first-party data at all.

Which platform provides the best buyer intent signals?

ZoomInfo leads in intent data, tracking signals from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings sourced monthly. Its Guided Intent feature identifies topics historically correlated with deal success. ZoomInfo was named a Leader in the Forrester Wave for Intent Data Providers in Q1 2025. Clari and People.ai focus on internal deal signals (activity levels, engagement patterns, CRM changes) rather than external buying intent.

How does pricing compare across Clari, People.ai, and ZoomInfo?

None of the three publish specific prices. All use enterprise-only pricing models. ZoomInfo is free to start with consumption credits based on usage. ZoomInfo Lite is a permanent free tier with 10 monthly export credits and no time limit, plus a separate 7-day free trial of the full platform. Clari offers five free Align licenses and a limited Copilot free trial. People.ai offers demos but no publicly available free access to its core platform, and users on TrustRadius consistently cite high cost as a consideration.

Which platform is easiest to implement?

People.ai reports that most implementations go live in 2-4 weeks, with two years of historical activity analyzed on day one. ZoomInfo's GTM Workspace is designed to deploy in weeks, and ZoomInfo Lite requires no implementation at all. Clari's implementation complexity depends on how many of its products you adopt; the platform recommends persona-based enablement and users typically need weeks to become proficient. All three face the common enterprise challenge that full adoption requires change management, not just technical setup.

Can I use ZoomInfo alongside Clari or People.ai?

Yes, and many enterprise teams do. ZoomInfo provides the data and signals layer (verified contacts, company intelligence, intent data, conversation intelligence via Chorus) while Clari or People.ai provides the revenue operations and forecasting layer. The combination gives teams both complete market data and pipeline intelligence. ZoomInfo's APIs and MCP access make it straightforward to feed its data into any downstream platform, including both Clari and People.ai.
