Debug Something Interesting.
Build with Us.

We're a Silicon Valley startup, building open-source AI tools, and we're looking for talented developers to join the journey.

Who We Are

Zvonimir Sabljic

Co-founder & CEO
Show bio

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.

Show bio

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.

Life at Pythagora: Builing the Future Together

Here at Pythagora, we like to think of ourselves as a team of builders. Not just builders of code, but of ideas, connections, and possibilities.

We're a small group of problem-solvers and creators, working together to transform how apps are built. Our "band" isn't made up of guitars and drums but of 14 AI agents collaborating with developers to create production-ready apps faster than ever before.

Like any great team, we depend on each other—humans and AI alike—to make something incredible.

We've built Pythagora on the foundation of collaboration and curiosity. It's more than just an AI-powered development tool; it's a culture of innovation. Whether it's our open-source roots with GPT Pilot (32k GitHub stars and counting!) or our commitment to the Functional Source License, everything we do is about redefining what's possible while staying open, transparent, and thoughtful about the impact we create.

Ego blocks innovation. Always.

Lets build the future together.
