Our Cofounders


Leon Ostrez
I've always been passionate about technology, culminating in a Master's degree in computer science. My career has spanned freelancing for tech startups and working as a contractor for Ericsson Nikola Tesla, fueled by my love for problem-solving and programming.

At college, I met Zvonimir, and at Faze Clan as a lead engineer, we explored using AI and Machine Learning to craft pixel-perfect websites. Beyond work, I'm an avid board game player, nature enthusiast, and have competed in sailing for seven years. My life is also enriched by my two 1-year-old Croatian Shepherds, Ria and Luna, adding joy and energy to my daily routine.
Zvonimir Sabljic
I graduated with a Master's degree in engineering at University of Zagreb after which I ventured into the tech world with big dreams and a knack for solving problems. In 2016 I started leading a project called A Web Whiteboard, and 5 years later, after reaching 1.5 MAU, we sold the company to Miro. After the acquisition, I started learning ML with Leon and playing with different ideas.

In 2023. we created our first open-source project for making automated tests autonomous which got early success and quickly reached 1.4k Github stars. After talking to users and seeing how AI is evolving, we decided to build GPT Pilot, which quickly became one of the fastest-growing open-source projects. Finally, in October 2023. we decided to build Pythagora, an AI system that helps you build fully functional Web Apps.
