Founders & team

Julian Frumar

Founder/User Experience Director

2 x YC technical founder (with 1 exit to Google). A mix of leadership and IC work over my career, dominated by zero-to-one product design & development in startups. Entrepreneurship has crafted me into a resourceful generalist, with a specialization in the Frontend stack & user-facing features. I'm continually excited to learn and delve deep into new technologies, and do what's required to help find product traction and achieve success.
