About
Pythagora is a Zagreb, Croatia-based AI software development platform — backed by Y Combinator (W24) with $4 million in seed funding from 500 Global, YC, UpHonest Capital, Moonfire Ventures, Inovo, and Rebel Fund — providing 80,000+ software developers and development teams with an all-in-one AI software engineer that autonomously generates, debugs, tests, and deploys complete web applications from natural language prompts, supporting 20+ programming languages and frameworks including Node.js, React, Python, and Django. Founded in 2023 by Stjepan Golemac and Mario Stipetic, Pythagora's platform can build full-stack web applications (database schema, API routes, frontend components, authentication, testing) from a single conversation-style specification — positioning as the AI that writes the entire application rather than just completing individual code snippets within a developer's existing file.
