How to validate it in an afternoon
Before committing build time or a thesis memo to multi-channel marketplace uploaders, run three cheap checks against public engineering activity. Each takes minutes and none require access to private data.
- Count active builders. Search GitHub for repositories matching this category, then check how many accepted commits in the last 14 days. More than a handful of active teams means the category has energy, not just mentions.
- Look for the steady, one deal per month pattern in funding. If funded companies keep appearing here, a round closes somewhere in this category most quarters, neither hot nor dead. Cross-check the e-commerce infrastructure leaderboard to see whether any of the accelerators sit adjacent to this niche.
- Test the team-sized build cost assumption honestly: only makes sense as a team bet, multiple quarters of salary before any revenue, the kind of project incumbents are better positioned to start. If your calendar cannot absorb that, the opportunity is real but not yours yet.
