A16Z, a venture capital firm, and UC Investment, an investment office, led a $100m seed funding round in LMArena, an open community platform, with participation from Lightspeed, Laude Ventures, Felicis, Kleiner Perkins, and The House Fund. "AI evaluation has often lagged behind model development. LMArena closes that gap by putting rigorous, community-driven science at the center. It's refreshing to be part of a team that leads with long-term integrity in a space moving this fast," Ion Stoica, LMArena Co-Founder.
