What AICofounder Does Well
AICofounder is a useful early-stage brainstorm tool. If you have no domain in mind and want to riff on possibilities, a prompt-first AI cofounder is fine for opening doors. The output is a curated list of business ideas at speed.
The honest limit: every idea AICofounder generates still needs the same validation work you would do without it — reading 100+ real user complaints, scoring competition, checking if the buyer is reachable. That is the work BigIdeasDB automates.
