Scaling past 20 devs, our release QA cost exploded. The fix was moving the verify step into the agent loop
When our team went from a handful of people to 20+, the cost that scaled worst was release QA. More devs shipping more AI-generated code meant more flows to re-verify before each release, and it was eating real hours. And my weekends. Throwing people at it doesn't scale; the verification work grows faster than the team.
What moved the needle was changing who does the verifying. Instead of people confirming each change works in the live app, the coding agent does it inside its own loop. It runs a real session against the live app (through the TestSprite CLI), and when something regresses it gets a self-contained failure bundle it can act on and rerun. Passing checks pile up into a durable suite, so coverage compounds as we ship instead of decaying. People moved up to the judgment calls and the genuinely ambiguous cases.
Not a cure-all. It needs an account for the cloud side, and no tool replaces human judgment on the hard stuff. But shifting the routine verify-and-fix work off people and into the loop is what kept release QA from scaling linearly with headcount. How are other founders keeping QA cost flat as the team grows?
