Clari is usually the stronger choice for revenue forecasting, while Gong is better when sales leaders need call intelligence tied to deal risk. If the main problem is missed commits, poor pipeline hygiene, and weak board-level forecast confidence, Clari fits best. If the main problem is not knowing what buyers actually said, what changed in a deal, or why reps are overconfident, Gong adds sharper context.
TLDR: Clari is best for structured forecast management, rollups, pipeline inspection, and revenue process control. Gong is best for conversation intelligence, deal warnings, and coaching signals that improve forecast judgment. For example, a 60-person SaaS sales team might use Clari to raise forecast accuracy from 72% to 86%, while Gong reveals that 28% of “commit” deals have no confirmed next step. Many mature revenue teams use both, but smaller teams should buy the tool that fixes their biggest forecasting gap first.

Why AI sales forecasting still fails
AI forecasting tools promise cleaner numbers, but software alone does not fix a weak sales process. Bad CRM data, sandbagging, late-stage surprises, and loose stage definitions still ruin forecasts. The best platforms reduce noise. They do not make judgment optional.
Most forecast errors come from three places:
- Rep optimism: deals are called “likely” because the buyer sounded friendly.
- Data gaps: close dates, next steps, competitors, and stakeholders are missing.
- Manager bias: leaders adjust forecasts based on gut feel instead of evidence.
AI helps by spotting patterns humans miss. It can flag stalled deals, score pipeline quality, compare rep behavior, and detect buyer signals across calls, emails, CRM updates, and activity logs. Still, the output is only as good as the signals connected to it.
Clari: best for forecast control and revenue discipline
Clari is built for revenue operations and sales leadership. Its core strength is bringing forecast calls, pipeline inspection, deal scoring, and revenue analytics into one controlled system. It is less about coaching a single rep after a bad call. It is more about helping the company answer, “Will we hit the number?”
Clari works well when sales teams have multiple managers, territories, segments, or product lines. It gives leaders a clear view of commits, best case, upside, risks, and historical accuracy. Forecast submissions can be tracked by rep, manager, region, and quarter. That makes it easier to see who is consistently accurate and who is guessing.
Key strengths of Clari include:
- Strong forecast rollups for reps, managers, and executives.
- Pipeline health inspection across stages and time periods.
- Deal risk signals based on activity, stage movement, and close behavior.
- Historical forecast accuracy tracking.
- Useful revenue cadences for weekly and monthly business reviews.
The catch is that Clari needs process discipline. If CRM fields are messy, stage criteria are vague, or managers skip forecast hygiene, users may feel like they are staring at a prettier version of the same bad data. Setup also takes real effort. RevOps should plan field mapping, forecast category rules, user training, and executive reporting before rollout.
Gong: best for buyer truth and deal intelligence
Gong is strongest where forecasts depend on what buyers actually say and do. It records and analyzes calls, emails, meetings, and deal activity. That makes it valuable for detecting whether a deal has real momentum or only rep confidence.
Gong can show if pricing was discussed, if a competitor came up, if legal was mentioned, or if the economic buyer attended a meeting. These details matter. A deal marked “commit” looks very different when the last call had no decision maker, no timeline, and no agreed next step.
Gong is especially useful for:
- Understanding why deals slip.
- Finding missing stakeholders and weak next steps.
- Coaching reps on discovery, pricing, and objection handling.
- Comparing top-performer behavior against the rest of the team.
- Adding qualitative evidence to forecast reviews.
Honestly, it feels like Gong exposes the sales fiction that CRM alone lets people hide. A rep may say procurement is “almost done,” but Gong can show no procurement call has happened in 21 days. That is uncomfortable, but useful.
Its weakness is that it is not always the cleanest system for full revenue forecasting. It can support forecast accuracy, but Clari is usually stronger for formal forecast workflows, rollups, executive views, and revenue board reporting.
Clari vs Gong: which one predicts revenue more accurately?
The honest answer is that they predict different parts of the revenue story. Clari predicts the number. Gong explains the conversation behind the number.
| Category | Clari | Gong |
|---|---|---|
| Primary use | Forecast management and revenue inspection | Conversation intelligence and deal insight |
| Best user | CRO, VP Sales, RevOps, sales managers | Sales managers, reps, enablement, RevOps |
| Forecast strength | High for structured rollups and accuracy tracking | High for deal signal quality and risk context |
| Main risk | Depends on clean process and CRM data | Can create lots of insight without a tight forecast workflow |
If your company misses the quarter because leaders cannot trust rollups, choose Clari first. If your company misses because reps misread buyers, choose Gong first. If both problems are real, the combination can be powerful.
Other AI tools for sales forecasting
Clari and Gong get much of the attention, but they are not the only options. The right pick depends on company size, CRM stack, budget, and how much change the team can absorb.
Salesforce Einstein
Salesforce Einstein makes sense for teams already committed to Salesforce. It can score opportunities, suggest next actions, and provide forecasting analytics inside the CRM. This reduces tool switching. The downside is that results depend heavily on Salesforce discipline. If reps treat CRM as admin work from last Friday, Einstein will struggle.
Microsoft Dynamics 365 Sales Insights
Microsoft Dynamics 365 Sales Insights fits companies using Microsoft’s sales and productivity tools. It brings predictive scoring, relationship insights, and activity intelligence into the Microsoft environment. It can be a practical choice for enterprises that want fewer vendors.
People.ai
People.ai focuses on activity capture and revenue intelligence. It helps connect seller actions to pipeline outcomes. This is useful when leadership wants to know which activities move revenue, not just which close dates look promising.
BoostUp.ai
BoostUp.ai is another serious revenue intelligence and forecasting platform. It offers forecast rollups, pipeline risk scoring, deal inspection, and sales execution analytics. It can be a good fit for revenue teams that want Clari-like forecasting features with a different product feel or pricing model.
Aviso
Aviso combines predictive forecasting, deal intelligence, and revenue operations tools. It often appeals to teams that want AI-driven guidance across pipeline, renewals, and account growth. As with any platform, the main question is not whether the model is clever. It is whether managers will use it every week.
What to check before buying
Too many companies buy forecasting software after one impressive demo. Then reality hits. Integrations take longer than expected. Reps complain. Managers run parallel spreadsheets. Expect to waste time on cleanup if the sales process is not ready.
Before buying, check these points:
- Forecast process: Are commit, best case, and upside clearly defined?
- CRM quality: Are close dates, stages, amounts, and next steps reliable?
- Leadership rhythm: Will managers use the tool in every forecast meeting?
- Data sources: Do you need calls, emails, meetings, CRM, product usage, or billing data?
- Reporting needs: Is the main audience reps, managers, the CRO, finance, or the board?
- Adoption risk: Will the tool save time, or add another screen to babysit?
Practical recommendation
For mid-market and enterprise SaaS teams, Clari is the safer first choice when forecast accuracy is the board-level pain. It gives structure, accountability, and repeatable forecast inspection. It is built for the revenue operating cadence.
Gong is the better first choice when the sales conversation is the blind spot. It helps leaders hear customer reality at scale. It also gives managers better coaching evidence and clearer deal risk signals.
The strongest setup is often Clari plus Gong, with CRM as the system of record. In that model, Clari manages the forecast, Gong supplies buyer evidence, and CRM stores core account and opportunity data. That stack is not cheap, so smaller teams should avoid buying both unless the forecast problem is costing more than the software.
A simple rule works well: if executives ask, “What number can we trust?” start with Clari. If managers ask, “Why do our deals keep slipping?” start with Gong. If both questions come up every Monday, your forecasting issue is not just a tool problem. It is a revenue process problem that AI can help expose, measure, and improve.
