In 1969, we landed on the moon and flew Concorde. Half a century later, we could do neither.
Blake Scholl founded Boom Supersonic (YC W16), the startup building America’s first supersonic airliner, to change that. At Startup School 2026, he shares how a cardboard mockup with Office Depot seats became XB-1, the first independently developed jet to break the sound barrier, and why founders have to build for both the worst day and the best day.
He also answers founder questions about teaching yourself hard things, breaking into hardware without the right resume, and finding work-life harmony while building something ambitious.
