Crevio vs Polsia
Two AI cofounders, side by side: which seats each one fills, what it really costs, and who should pick which.
Updated November 11, 2026
Full 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.
Full AI cofounder
Polsia made the autonomous-company idea famous and does run tasks every night without prompting. It loses ground on cost and trust: its cut of payments and of ad budgets adds up fast once you have revenue, it doesn't do refunds, and reviewers often mention credits spent on fixes.
