Headstart is built for people who want to think like founders. We work inside real enterprises ($100M+ ARR), shipping production AI systems that change how they operate. Every engagement is a different industry, a different problem, and a different set of constraints. You leave each one knowing that business deeply.
We are building our own platform, and have built our own coding agent Friday, which powers the majority of how we deliver. We're bootstrapped, cash-flow positive, and growing fast.
Engineers who thrive at Headstart are builders who want to understand both how businesses and code works. We take the work seriously and the culture deliberately. Pay is transparent, weekends are yours, and we don't confuse long hours with good work.
