On a quest to make 1,000 millionaires.

Legion Capital

Legion Capital is a different type of early stage investor. History is riddled with great ideas that never made it to market. We believe this happens when operators, the source of the best ideas to solve real problems, struggle to raise the right early stage money and aren't given the right set of investment objectives. Legion Capital writes angel- and seed-sized checks but maintains the ability to help raise and personally invest in Series A rounds. As an early stage investor, we insist on being an active investor and helping founders make smart technology and go-to-market decisions. The managing partners of Legion Capital are operators at heart. We understand the start-up roller coaster environment and want to help you navigate your endeavor armed with our knowledge of the minefield. If you have an idea and you’re ready for the rigors of the startup grind, contact us about joining the Legion.
