Meet the founders
In 2011, two developers, Darko Fabijan and Marko Anastasov, grew tired of slow continuous integration tools. They dreamed of creating projects without the customary beads of sweat, and releasing updates without hours of waiting. They knew they could do better, so they did. A year later, they released Semaphore, a product that enabled any developer to have a working CI/CD process in minutes.
What drives us
At the heart of Semaphore is a maker mindset: we care deeply about craft, learning, and doing meaningful work with kind people.
Create value
Focus on what matters most to users.
Collaborate openly
Build with trust and respect.
Continuously improve
Learn, ship, reflect, repeat.
Why open source
We believe developers should understand, shape, and trust the tools they use.
By open-sourcing Semaphore, we’ve opened up the same platform that runs millions of jobs every day, with full access to inspect, contribute and extend it under the Apache 2.0 license. Whether you use Semaphore as a hosted service or run it yourself, the code is yours to explore and improve.
