[niche professional vertical] in my response was a stand-in for the specific vertical my startup targets, which is light years from computer security. Computer security is a vertical where the practitioners are often developers or developer-adjacent. You're building tools for people like yourself. That's exactly the "scratch your own itch" dynamic I'm describing.

The vertical I'm in has zero overlap with the developer population. The end users aren't technical, don't participate on HN, and aren't going to "manage an agentic coding project." There's no equivalent of a developer who moonlights on OSS tooling because they're passionate about the problem space, because the problem space requires domain expertise that developers have no reason to acquire.
