Career
A Web Whiteboard and early ventures
Prior to founding Pythagora, Sabljić co-founded A Web Whiteboard (AWW), an online whiteboard platform for real-time visual collaboration. Under his leadership as CEO, the product grew to 1.5 million monthly active users before being acquired by Miro.[3] He also served as an advisor at Sheetgo, a Madrid-based SaaS company that automates workflows from spreadsheets.
Pythagora
Sabljić co-founded Pythagora in 2023 alongside Leon Ostrez and Senko Rašić. The platform is described as an all-in-one AI development tool that allows users to go from an idea to a production-ready application by conversing with the system in natural language. Pythagora uses large language models to automate developer workflows such as debugging and refactoring, and iteratively requests user feedback throughout the development process. It generates full application specifications from a prompt, then builds the frontend and backend in stages, allowing users to review and refine each component before deployment.[4]
The platform is built on top of GPT Pilot, an open-source AI coding tool also created by the Pythagora team, which has accumulated over 32,000 stars on GitHub.[1]
In May 2024, Pythagora closed a $4 million seed funding round co-led by Y Combinator and Polish venture capital firm Inovo VC.[5] In June 2025, the company launched its full platform with specialized AI agent teams designed to unite front-end, back-end, and debugging capabilities in a single environment.[6]
Pythagora has received coverage from outlets including Forbes, DevOps.com, ZDNet, and SiliconANGLE.
