Hi, I’m Julien. I am currently CPO at ByteRover. I love building AI products and developer tools in my free time. I previously co-founded Station (YC W18), which reached 1M+ downloads and 120K daily active users. We raised $4M from Accel and other investors. Before that, I scouted startups across 42 countries for Swiss investors and built a network of 150+ investors, accelerators, and ecosystem partners.
