Clari Forecast vs Gong (2026)
This is an adjacent pair more than a rivalry, and plenty of revenue teams run both: Clari's merger commitments list its Gong integration among those left unaffected. The decision is which record the forecast is built on, and what the vendor has said about training on it. Gong started from the recorded conversation and states on its trust page that customer data is never used to train generative models, backed by audited certification against the international standard for artificial intelligence management systems and nine named certifications. Clari started from the forecast, sells it to finance as well as sales, and holds the first A on outcome evidence in the GTM Tech Index, including a Leader placement in Gartner's first Magic Quadrant for Revenue Action Orchestration in December 2025. Where each is weakest mirrors that. Salesloft, which now sells Clari Forecast, states that customer data is never used to train models for other customers, though its MSA allows aggregated, anonymized use. Gong now feeds third party account and contact data into the Revenue Graph through Gong Enrich, which names ten data partners including Apollo, Lusha and ZoomInfo, without publishing the license terms behind them.
- Finance owns your number. Clari addresses finance as a named buyer alongside revenue operations, sales, marketing, post sales and sales engineering, and a strategic partnership with Workday carries its forecast into financial planning, a buyer almost nothing else in this index serves.
- You want independent evaluation before you shortlist. The GTM Tech Index awarded its first A on outcome evidence to Clari: a Leader in Gartner's first Magic Quadrant for Revenue Action Orchestration in December 2025, a Leader in Forrester's Revenue Orchestration Platforms evaluation in 2024, and third party economic studies with figures attached.
- You want to read the contract before the sales process starts. Clari's master subscription agreement, shared with Salesloft since February 2026, is published in full at a dated address, and the same agreement covers Salesloft's cadence and engagement products, so forecasting and sequencing sit with one vendor.
- The training question is the one your security team will ask first. Gong states on its trust page that customer data is never used to train generative models, without hedging, and backs it with audited certification against the international standard for artificial intelligence management systems and a governance team with a published remit.
- Integration should not be a line item. Gong's pricing page states the existing technology stack can be integrated at no extra cost, beside a partner marketplace, two way sync with the system of record and a warehouse export product that pushes enriched data into your own data platform continuously.
- Your security review wants breadth. Gong publishes nine certifications and attestations on its own page, each named and explained, including two privacy certifications, one of them specific to a processor holding personal data in public clouds, and it lets customers bring their own encryption key.

The short version of each
Clari Forecast
Clari Forecast is Salesloft's forecasting product, formerly the Clari platform, and it projects the quarter and inspects deals from a data layer that captures activity from the system of record, calendar, email and conversations. Clari merged with Salesloft on 3 December 2025, and the conversation intelligence and deal management Clari once sold now continue as part of Salesloft, with Groove under its own sign in. The GTM Tech Index grades it A on operational and outcome evidence, the first A on that axis in the index, citing Leader placements from Gartner and Forrester, and A on security certifications, ecosystem depth and segment coverage. It holds the privacy information management certification and publishes its master service agreement at a dated public address. It grades D on commercial transparency, with no price published anywhere, and its stewardship now rests on a stated rule that customer data never trains models for other customers.

Gong
Gong created the revenue intelligence category and sells what it calls a Revenue AI Operating System, built on a data layer connecting calls, emails, meetings and records from the customer's system of record, with sequencing, forecasting, enablement, warehouse export and an agent layer around the founding conversation product. The company reports annual recurring revenue above five hundred million dollars and more than five thousand customers. The GTM Tech Index grades it A on six axes: artificial intelligence safety and data stewardship, where its trust page states customer data is never used to train generative models, data privacy, security certifications, ecosystem depth, outcome evidence and deployment. It holds audited certification against the international standard for artificial intelligence management systems and publishes nine certifications by name. It grades C on commercial transparency, publishing the pricing model without a number, and B on recipient disclosure for recorded calls.

Common questions
Is Clari better than Gong?
They answer different first questions. Gong is built from the recorded conversation outward and holds the stronger compliance record, with fourteen axes at A or B against Clari's ten in the GTM Tech Index, including an unhedged statement that customer data never trains generative models. Clari is built from the forecast outward, serves finance as a named buyer and holds the index's first A on outcome evidence. Many enterprises run both, and Clari's merger commitments keep its Gong integration in place.
Does Clari or Gong train AI on my data?
Gong states on its trust page that customer data is never used to train generative models, and the GTM Tech Index grades it A on stewardship for saying so plainly. Salesloft, which now sells Clari Forecast, states that customer data is never used to train models for other customers, and its AI subprocessors may use customer data only with the customer's permission. Its MSA still allows aggregated, anonymized use of customer data, and an admin can switch all generative AI off.
Can I use Clari and Gong together?
Yes, and many revenue teams do. Clari names Gong among its integrations alongside Salesforce and HubSpot, and the frequently asked questions it published on the Salesloft merger commit that existing integrations are unaffected. Gong states that customers can integrate their existing stack at no extra cost. The practical question is which system holds the forecast of record, since both now sell forecasting, and which one your recorded calls live in. Graded by GTM Tech Index against seventeen capability axes from each vendor's own published materials, verified September 21, 2026. No vendor pays for placement.
How do Clari and Gong price?
Neither publishes a number. Gong grades C on commercial transparency and Clari grades D. Gong states the model: per user licenses plus a platform fee that scales with the number of users, integrations included, behind a form that asks for your team size band before it loads. Clari publishes no price, tier or term and is now quoted through Salesloft's sales team. Graded by GTM Tech Index against seventeen capability axes from each vendor's own published materials, verified September 21, 2026. No vendor pays for placement.
How does the GTM Tech Index grade Clari and Gong?
Both are graded on the same seventeen capability and compliance axes from public sources, at a documented depth of sixteen each. Gong takes A on stewardship, data privacy, security certifications, ecosystem depth, outcome evidence and deployment, and B on eight more. Clari takes A on outcome evidence, security certifications, ecosystem depth and segment coverage, and B on data licensing, privacy, platform terms and deployment. On commercial transparency Gong grades C and Clari D. The index publishes no composite score and declares no winner.

Two silences are shared, and one sits at the center of what both companies sell. Neither publishes an accuracy or error figure for its forecast: Clari for the projected forecast that is its founding product, Gong for the deal scoring and forecast validation it now sells beside conversation capture. Both publish customer outcomes, and neither says how often the number is right. The second silence is the other party on a recorded call.
Gong's recorder, and the Clari Copilot recorder that now continues as part of Salesloft, capture conversations with prospects and customers who never contracted with either vendor. Gong documents consent pages that an administrator can require before recording and an audio announcement to external participants, while the Clari side states no position on whether its recorder announces itself.
Two party consent statutes apply across many jurisdictions, and neither vendor states a position on article 50 of the European artificial intelligence regulation. The benign reading is that both leave consent to customer configuration. On training, Salesloft now states that Clari customer data never trains models for other customers. Ask both in writing for forecast accuracy against actuals, recorder behavior on joining a call, and whether any model is trained across customers.
