Leon Ostrež is a software entrepreneur and co-founder of Pythagora, an artificial intelligence startup that develops an all-in-one AI development platform. The company participated in Y Combinator's Winter 2024 batch.[1] Ostrež co-founded Pythagora in 2023 alongside Zvonimir Sabljić.
Career
Ostrež and Sabljić founded Pythagora in 2023 with the goal of building an AI-powered platform capable of generating full, production-ready web applications from natural language descriptions. The platform is built on top of GPT Pilot, an open-source tool developed by the team that has accumulated over 32,000 stars on GitHub.[2]
Pythagora's platform uses large language models (LLMs) to automate developer workflows, including debugging and refactoring. The development process is designed to be conversational: a user begins with a prompt describing their idea, and the platform generates application specifications, builds the frontend and backend iteratively, and solicits user feedback at each stage. Once complete, the application can be deployed and shared through the platform. The company describes itself as operating in the fields of artificial intelligence, developer tools, security, and web development.[1]
Pythagora was accepted into Y Combinator's Winter 2024 cohort. In 2024, the company raised $4 million in seed funding to further develop its platform. By mid-2024, Pythagora had reportedly accumulated approximately 30,000 active users. As of 2023, the company had seven employees.
The platform functions as an IDE extension, integrating into existing development environments such as Visual Studio Code. Rather than serving as a code autocomplete or snippet-generation tool, Pythagora is designed to manage the entire application development lifecycle — from initial concept through deployment — distinguishing it from many other AI coding assistants on the market.
Pythagora has received media coverage from outlets including Forbes and other technology publications, as indicated by press logos featured on the company's website.[2]
