About the project: the product is a Y Combinator-backed startup building the next-generation internal developer platform (IDP) - a unified interface powered by AI agents that automates all the annoying engineering tasks outside the code editor: deployment, performance, incidents, and bugs. The product is already being tested by engineers at OpenAI, Google, and NASA.
