AI評価プラットフォーム「Arena」が設立から8ヶ月で資金調達1億ドル達成

Arena has crossed $100M annualized revenue run rate within eight months of launching our enterprise offering. We never could have imagined that our student project at UC Berkeley would become one of the fastest-growing companies of all time. Thank you to our community — all 10M+ of you — for contributing the hundreds of millions of conversations and tens of millions of votes that allow us to evaluate real-world AI capabilities.

By contributing your votes, you are not only helping us sustain a free and independent platform, but also guiding AI towards your values. Arena works with AI labs to evaluate their models transparently and openly, ensuring they benefit humanity. Much like democracy, participation is critical, because voting is the mechanism that allows us to represent people.

This revenue milestone signifies that we have built a durable business around our mission. We plan on continuing to invest in arena.ai, building better features, more tools, and new ways to work with AI. Agent Arena is already a huge step in this direction, enabling evaluation of objective task completion and hallucination rates for long-running agentic tasks, even where static benchmarks fail. We launched Agent Mode just a month ago, and it's already seeing 5M+ turns per month and growing 10% week over week. We would love your feedback on what to build next.

We’re only accelerating from here. The Arena platform has 700M+ total conversations, 82M+ total votes, and over 10M+ monthly visitors. If you want to be part of our growth as a customer, partner, investor, or anything else, please reach out directly to me on X: @ml_angelopoulos. And if our mission inspires you, apply for a job at arena.ai/jobs. We are excited to shape the future of AI through frontier evaluation research together.

Warmly,

Anastasios CEO and co-founder
