Become a design partner
We are looking for 5 to 8 engineering teams to use Belay on their own codebase, for debugging and onboarding, and to tell us what works.
Who it suits
- Product engineering teams of 10 to 200 developers.
- Teams that work on a large or legacy codebase.
- Teams that use TypeScript or Python, the two stacks the prototype supports.
What it involves
We aim to be working with the first three design partners by Q2 2027.
- You use Belay for legacy-code debugging and onboarding, on your own code.
- We measure the work against time-to-fix, together.
- You tell us what helped and what did not. That shapes what we build next.
Your code
How your code will be handledJoining means sharing access to code, so read the Security page first. Our data-handling policy is not yet published. Ask us anything about it in your application.
Apply
Tell us about your team. The founder reads every application and replies by email.
AI that climbs with you, not for you.
Work with us as a design partner: bring a large or legacy codebase, and help decide what Belay becomes.
