Julien Martin — Founder

Building Offmarket, a community and newsletter connecting top designers with the best opportunities. Writing The Playbook, a newsletter on design, startups, and building. I’ve spent 17 years in digital product design, shipping over 100 projects across Behance, Zenly, amo, and other ambitious teams. From launching apps loved by millions to advising early founders, I’ve seen how design shapes not just products, but entire companies. What drives me now is helping the next generation of startups and designers connect: 1. Hiring differently: matching world-class talent with the right founders and ideas. 2. Sharing openly through The Playbook and writing on design, growth, and product building. 3. Advising and Investing selectively backing founders and great ambitious products through Source Ventures. If you’re building, designing, or hiring, my work likely overlaps with yours.
