Dr. Igor Ryabenkiy, Founder and Managing Partner at AltaIR Capital, came to venture investing through an unusually technical and hands-on path, from programming underwater robots to building and splitting up his own company, and his core belief that founders need relentless focus grew out of watching his own startup lose direction after it strayed from its core product. He invests like a builder rather than a pure financier, judging founders by whether they can explain their idea clearly in 30 seconds, mentoring people like Miro's Andrey Khusid well before formally investing, and personally putting his own money into every fund he raises.
