Alumni Q&A

How did your company get started? (i.e., How did the founders meet? How did you come up with the idea? How did you decide to be a founder?): Senko and Zvonimir met at a 2016 startup event, built a side project into a company, and sold it to Miro in 2021. Zvonimir and Leon, friends since starting college in 2009, learned ML together after the acquisition and in 2023 released an open-source AI test-generation tool that reached 1.4k GitHub stars, later pivoting to the fast-growing GPT Pilot project. In October 2023 the three combined their overlapping efforts to build Pythagora together.

Summarized from the founders' answers on their Y Combinator profile.
