David Kooi – a one-person, AI-native product studioI run Skylark Creations, a one-person, AI-native product studio in Colorado. I design, build, and ship software, and I measure success by one thing: whether someone would tell a friend about it. In 2026 the same studio system started running client engagements end to end.Previously I co-founded and led Jointly (2018-2025), where I wrote the Theory of Purposeful Cannabis Consumption and launched the industry's first AI-powered product-recommendation assistant. Before that I founded and sold Santa Monica Mountains Cyclery to Trek Bicycle.I hold an MBA from the University of Chicago Booth School of Business, a B.A. from Northwestern University, and a B.S. in Computer Science from Oregon State University.
