What began as a UC Berkeley research project has become one of the fastest-growing and most trusted AI infrastructure companies in the world. This week, the vision set forth by Arena founders @infwinston and @ml_angelopoulos reached another remarkable milestone: @Arena announced it has surpassed $100M in annualized revenue run rate just eight months after launching its enterprise offering, while growing to a community of more than 10 million users helping shape how frontier AI models are evaluated. In the @Felicis profile on the company, Wei-Lin and Anastasios shared how they approached building a platform rooted in scientific rigor, neutrality, and community trust; principles that have become even more important as AI capabilities accelerate. We've been true believers in Arena since Seed.
