The Opportunity

Problem

Remote workers bootstrapping web3 SaaS products can't acquire non-crypto paying customers and deal with constant gas fee complaints, making it impossible to gain traction.

Solution

FiatBridge integrates Stripe into your web3 app, converting fiat subs to crypto payouts while sponsoring all user gas fees. Non-crypto customers pay normally via card, and your app handles seamless web3 interactions behind the scenes. No more complaints—traction starts immediately.
