“We cut our QA cycle time by 70%. Instead of relying purely on human review, now we instantly know which prompts are failing and why.”
We embedded Composo into our AI Workers from day one - best decision we've made on testing. As an early stage start-up, we can't afford to waste time on manual evals or debugging. They provide peace of mind for us and our customers. No brainer.
For the first time, we can ship with complete confidence knowing exactly what our AI quality looks like at scale.
