Used this approach for a project management tool I launched earlier this year. Went in skeptical but the actual experience was different from what I expected. The biggest win was moving from idea to working prototype in weeks without spending months finding a technical partner. Working with an ai cofounder let me cover architecture decisions, feature scoping, and code structure without needing someone in the room for every call. There are limits when things get complex, but for an early-stage solo founder it removes the single biggest blocker most people run into
