Clerk helps developers ship authentication in minutes, and the sales motion lives and dies by fast follow-up. When a developer calls, they expect an answer now.
The challenge
With a self-serve product and a lean sales team, Clerk found that inbound calls came in bursts — product launches, weekends, and late nights. Missed calls meant missed trials, and slow follow-up meant lost momentum.
Rayz AI picks up every call, answers our docs-level questions, and books a demo the moment a trial is running. It turned our voicemail into a meeting booker.
The solution
Clerk pointed inbound voice at Rayz AI, trained on the product docs and pricing. Callers get immediate answers, interested developers get a demo booked, and every interaction is logged to the CRM alongside their account.
The results
| Metric | Result | | --- | --- | | Trial-to-paid conversion | +38% | | Time to close | 24% faster | | Calls answered after hours | All of them |
The bottom line
Clerk's team went from playing catch-up to closing deals. Rayz AI answers when developers call, so momentum never dies waiting on a callback.
