Justin Mares

Co-author (with Gabriel Weinberg) of Traction — the most widely used framework for startup customer acquisition — and serial entrepreneur in the health tech space.

Traction as the startup growth manual: Mares and Weinberg's framework systematized startup customer acquisition into 19 'traction channels' (SEO, content marketing, paid ads, virality, sales, etc.) with a process ('Bullseye Framework') for identifying which channel to prioritize. The book became the default resource for founders trying to figure out how to get their first customers, filling a gap between product development and growth.
