US founder buying checklist
Launch surface
Decide whether the launch needs web only, mobile only, or web plus mobile.
Billing
Ask how Stripe, subscriptions, customer portals and plan logic are generated or integrated.
Ownership
A founder should own the repo, domain, store accounts and customer data path.
Iteration speed
The best tool is the one that can ship version 2 after customer feedback, not only version 1.

FAQ
What should US founders look for in an AI app builder?
Look for launch speed, backend/auth/database support, billing path, code export, mobile publishing support if needed, and a workflow that can handle version 2 after customer feedback.
Is web-first enough for a US MVP?
Sometimes. If the customer acquisition path is SEO, ads or B2B sales, web-first may be enough. If the product depends on push notifications, camera, location, consumer retention or marketplaces, native mobile becomes more important.
