Founder signal

“We shipped our MVP almost entirely with AI-assisted coding. We were proud of the velocity until Rapid Securities showed us API keys and a billing-related secret sitting in the client bundle. We had no idea they were reachable from the browser. They walked us through rotation and fixes, and we patched it all before a wider release.”
