Crevio vs IdeaBuddy
Two AI cofounders, side by side: which seats each one fills, what it really costs, and who should pick which.
Updated November 11, 2026
Crevio9.1Full AI cofounder, higher score
The only tool we reviewed that fills all four founder seats on its own and keeps working after launch. It researches the idea, builds the site and app, sells through checkout, email, social, ads and phone, and runs standing tasks on a schedule or when something happens, like a new order or a failed payment. Payments land in your own Stripe account, and anything risky can wait for your approval.
IdeaBuddy3.5AI idea and planning partner
A friendly, guided planner for first-time founders, with a free plan and a refund window. Like the other planners, it stops at the plan.
