I've been writing software since 5th grade. I cofounded Ride with GPS in 2007 and still write code every day. I've always got side projects going.

Stepwise came out of frustration. Keeping an agent on the rails through a complex multi-step flow is unreliable. Context management matters and gets messy fast. Validation and parallelism are hard to get right. And even when you nail all of that, the result is usually a black box, so debugging is painful. I kept solving these same problems by hand, so I built an engine that solves them structurally.

Most workflow tools also treat humans as an edge case. Real pipelines have people in them. Someone needs to approve something, review an output, make a judgment call. Stepwise treats human steps as first-class.

More broadly, I'm interested in coevolution between human and AI intelligence. Not the adversarial framing, but two forms of intelligence developing together, each compensating for the other's blind spots. Stepwise is one expression of that.
