Weâre excited to double down for @arenaâs $200M Series B. As AI models multiply, knowing how they actually perform in the real world is becoming increasingly important. Arena is also launching its Alignment Index, which measures how closely AI behavior aligns with human values in real-world settings, contributing to Arena's mission to measure AI through the experience of people who use it. We first partnered with the team at the seed. Since their Series A, Arena has exceeded $100M in annualized revenue, with millions of people helping evaluate frontier models through real-world use. That growth reinforces our original investment thesis that the more models there are, the more valuable independent signals about their performance become. Congratulations to co-founders @ml_angelopoulos, @infwinston, and @istoica05. As the model race gets more crowded, Arenaâs work has been getting even more interesting.
