Pros
This is the kind of role where you actually get to shape things, not just execute someone else's playbook. The product is genuinely differentiated (not another wrapper on top of an LLM), leadership is accessible and sharp, and the team is small enough that your work matters on day one. I've learned more in a few months here than I did in years at a large tech company. The caliber of people they've assembled for this stage is rare.
Cons
It's early. Really early. Processes are still being built, roles blur together, and there are days where you're context-switching between five completely different things before lunch. If you need clearly defined swim lanes and a mature org chart to feel comfortable, this isn't the move yet. The ambiguity is real, but that's also kind of the point.
