An underrated freelance niche: AI-assisted QA testing for solo developers
A freelancer spotted a gap: solo developers shipping apps (one had 11k users) get buried by bad reviews because they only test manually on their own phone. The pitch is AI-assisted regression testing across devices, sold to indie devs and tiny agencies. No income figures yet — it's a niche idea from a single case — but the pain point is concrete and the buyer is easy to find.
