In this episode of the Progression Project, Erik sits down with Alex Aguera, founder of GoFoil and one of the true originators of modern foiling, to put the real beginning of the sport on record. From hand-building the first high-lift foil for Kai Lenny in 2015 to the now-legendary sessions that sparked surf, downwind, and everything that followed, Alex shares the firsthand story behind the viral moment that changed watersports forever. The conversation traces foiling’s Maui roots, the early experiments with Kai, Laird Hamilton, and Dave Kalama, and how curiosity, engineering intuition, and the right environment collided to create an entirely new way of riding waves. Along the way, Alex dives into para-winging, Foil Drive, modern foil design, and what it feels like to watch something you helped invent reshape lives and ocean culture around the world.
