Your business stays yours
The database checks on every request that a business belongs to you. Over 70 automated checks make sure one founder can't see or change another's data.
Fy can only touch your business
Fy works with your own sign-in, so the same rules apply to it. It can't read another founder's business even if asked.
Layer by layer
Nothing goes out without youPosts, emails and ads start as drafts. Only you can approve them, and only the server can send them.
Keys kept secretOur keys for AI, the database and payments live on the server, never in your browser.
Encrypted connectionsAccess to your social accounts is stored encrypted and only the server can read it.
Limits on every sendDaily caps on emails and on Fy's work, so a mistake can't run away.
Payments by StripeStripe hosts the payment forms. Founderfy never sees card numbers.
Credits only change on the serverNobody can add credits or start a plan without paying, and each payment counts once.
