VERDICT: BUILDBERG SCORE 79/100

01 THE IDEA

Millions of non-technical founders and creators are now building apps with AI coding tools like Cursor, Replit, and V0, but consistently hit walls they can't debug alone. Last 20 is a 'phone-a-friend' service where a stuck builder uploads their code, describes the problem, and gets matched with an expert for a short screen-share session. Sessions are priced at $15–$50 each, with agency annual plans at $100–$500/year, and the platform takes 5–15% of expert earnings.

The go-to-market is a value ladder: a free AI project roadblock guide to capture emails, a low-cost Chrome extension to capture and submit issues, pay-per-session expert access, and eventually annual subscriptions and enterprise packages. The natural starting point is to dominate one platform (e.g., Cursor, V0) before expanding to cover the full vibe coding ecosystem.

03 THE VERDICT

This idea has excellent timing, a clear and emotionally resonant pain point, a proven adjacent model (Replit Bounties), and a massive and rapidly growing TAM of non-technical builders. The 'start with one platform' strategy is smart — CursorHelp.com or V0Bounties.com as a focused beachhead is very executable for a solo founder. The 15-minute session format is clever and lowers the friction barrier significantly versus traditional freelance platforms.
