Luke Zaientz
Luke Zaientz is the co-founder and CEO of OTTO SPORT AI, a Minneapolis-based startup building an AI-powered operating system for the messy, multi-billion-dollar world of youth sports. He has spent more than a decade turning the unglamorous back-office of clubs, leagues and tournaments into real businesses: he co-founded Reigning Champs (parent of NCSA College Recruiting), grew it past $200M in annual revenue through ten acquisitions, and saw it sell to IMG Academy and later to EQT in a deal valued at $1.2B. Before sports he co-founded RMG Networks and took it to IPO with Kleiner Perkins backing, and launched Match.com Events from zero to half a million attendees. In January 2026 OTTO SPORT AI launched with a $16.5M seed round co-led by Mamba Growth Equity and Rally Ventures, where Zaientz is also an operating partner.
Umut Isik
Umut Isik is the co-founder and CEO of Incept AI, a New York voice-AI company that takes drive-thru and phone orders in the noisiest places on earth. A former algebraic geometer turned Principal Applied Scientist at AWS, he spent years building neural networks that pull a single human voice out of acoustic chaos. He also makes mathematical art from simple functions. Incept AI raised a $3M pre-seed led by Rally Ventures in February 2025 and claims 95-97%+ order accuracy with no human in the loop.
