Gong vs Sybill (2026)
The decision is whether the team needs a conversation platform for the whole revenue organization or an assistant that takes admin off each seller. Gong records calls and runs them through its Revenue Graph into forecasting, engagement, enablement and agents, priced per user with a platform fee and no published rates. Sybill records meetings, writes summaries and pre meeting briefs, drafts follow up email in the rep's own voice and fills CRM fields after each call, with published plans at $30 and $90 per user a month on annual billing and AI credits for anything a user asks it to do. The two can also run together, since Sybill can pull recordings from Gong rather than replace the recorder. Gong documents far more about data handling, from US or EU storage to a 30 day export window after termination, while Sybill's agreement ends service at termination with no export terms. Sybill's contract also lets it train its own models, its expression recognition and speech to text engines among them, on customer recordings in anonymized form, with no opt out. Sybill suits sellers who want follow up and CRM updates handled after every call. Gong suits a team putting call data at the center of forecasting and coaching.
- Revenue leaders want call evidence inside forecast and pipeline reviews through Gong Forecast.
- Recordings must stay in the EU. New Gong customers choose US or EU storage on AWS.
- Procurement needs written exit terms. Gong's terms give 30 days after termination to export recordings before deletion.
- Sellers lose hours to follow up email and CRM entry. Sybill drafts the email and fills CRM fields after each call.
- The team wants to start small on a published rate, from a free plan to $30 per user a month on Pro.
- Gong already records the calls. Sybill can pull those recordings in and add its assistant on top.

The short version of each
Gong
Gong sells conversation intelligence as the base of a wider revenue system. Calls, meetings, email and messages feed its Revenue Graph, which also carries third party account and contact data, and Gong Forecast, Engage, Enable and a set of agents act on it, from flagging deal risk to drafting the next email. The platform connects to more than 300 tools, syncs both ways with Salesforce, Dynamics and HubSpot, and offers open APIs, webhooks, an MCP server and warehouse delivery through Gong Data Cloud, and the GTM Tech Index grades it A on ecosystem and integration depth. Customers decide at sign up whether their data lives in a US or EU data center on AWS. A buyer gets no number before a sales conversation, since the pricing page lists per user licenses and a platform fee without rates.

Sybill
Sybill is an AI assistant for sellers that works from calls, email, dialers, Slack and the CRM. It records meetings, including through an invisible recorder and a mobile app for in person meetings, writes summaries and pre meeting briefs, drafts follow up email in the rep's tone, and answers questions across deals in Ask Sybill. On the $90 Business plan it also fills ten CRM fields after every call and opens API and MCP access for Claude and other tools, and the GTM Tech Index grades it B on commercial transparency because every plan except Enterprise carries a published rate. AI credits reset weekly and are spent only on requested work such as pipeline analysis, decks or MCP calls, while summaries, briefs, follow ups and CRM updates cost nothing. Pro costs $30 per user a month on annual billing.

Common questions
Can Sybill work alongside Gong instead of replacing it?
Yes. Sybill's pricing page offers two paths for teams already on Gong, Chorus or Fireflies: replace the recorder entirely, or connect it and pull its recordings into Sybill for answers across calls and deals. Running both means paying Gong's per user licenses and platform fee alongside Sybill's seats, and Sybill's cross deal answers and CRM Autofill sit on its $90 Business plan. Graded by GTM Tech Index against seventeen capability axes from each vendor's own published materials, verified October 14, 2026. No vendor pays for placement.
How do Gong and Sybill charge for AI usage?
Sybill gives each plan a weekly credit allowance, 500 on Free, 2,500 on Pro and 5,000 per user on Business, and spends credits only when someone asks for work such as a pipeline analysis, a deck or an MCP call. Summaries, briefs, follow up emails and CRM Autofill cost nothing. Gong's terms allow usage based fees alongside subscription fees as each order form sets out, with no rates on its pricing page. The GTM Tech Index grades Gong C and Sybill B on commercial transparency.
Does the Sybill free plan record calls?
Sybill's own page disagrees with itself. The Free plan card lists unlimited call recordings and an invisible recorder, while the pricing FAQ says free licenses can use Ask Sybill, view summaries and watch recordings but not record meetings, and a lapsed trial moves to a collaborator license that cannot record. Pro at $30 per user a month on annual billing records without limits. Gong lists no free plan on its pricing page. Graded by GTM Tech Index against seventeen capability axes from each vendor's own published materials, verified October 14, 2026. No vendor pays for placement.
Where does Gong or Sybill keep recordings and deal data?
Gong lets new customers pick a US or an EU data center on AWS, with 24 hour recovery objectives, and the GTM Tech Index grades it A on deployment and data residency. Sybill also runs on AWS, inside a virtual private cloud with a recovery time objective of 24 to 48 hours, but its agreement allows hosting in the United States or other locations with no region choice, and the GTM Tech Index grades it C on the same row.
What happens to Gong and Sybill data at the end of a contract?
Gong's terms give 30 days after termination to request data, recorded calls included, for export before deletion, and its renewal notice of 60 days can go by email. Sybill's agreement renews yearly unless notice arrives 30 days before the end by courier or mail, and it ends all services at termination with no export window. The GTM Tech Index grades Gong B and Sybill C on exit and data portability. During the term, Sybill's paid plans store data without limit.
