BrainGrid

The product is a plan-first app-building platform that addresses AI-generated software that breaks as features are added by writing a specification with acceptance criteria and readiness checks, then building and verifying the application before delivery. It is for developers and executives in businesses that need SaaS products, internal tools, AI-powered apps, or marketing sites. Unlike tools that jump straight to code, it requires spec sign-off first and proves each requirement works with evidence before shipping a live product the customer owns.
