Arena has crossed $100M in annualized revenue run rate, eight months after launching our evaluation product. With our recent release of Agent Mode, millions of users on Arena are doing real work with agents, from coding to document analysis, in long-running, multi-turn sessions with hundreds of tool calls. Arena now evaluates objective criteria like task completion rates, hallucination rates, and more, far beyond our original human preference voting model. This expansion has taken us from a student project at Berkeley to one of the fastest growing companies in history. Go Bears! 🐻 Our core thesis is simple: to align AI with human values, we must directly measure its impact on people in the real world. Today's milestone is proof that Arena’s platform is the de-facto standard for post-deployment evaluation of AI.

🔒 LOCKED IN: Eliott Lindberg (@robiot) left @Lovable at 18 to start his own company.

8 months ago, we shipped the first Pocket. Today, 100,000 people use it to be present in their most important conversations. Grateful to have @Accel, @peakxvpartners, @ycombinator, @rauchg, @mati, and @nejatian behind us for what comes next.
