UC Berkeley research project hits $1.7B valuation in 7 months

LMArena just closed a $150M Series A at $1.7B post-money valuation — tripling from $600M in May 2025. The AI model evaluation platform went from academic project to unicorn faster than most startups reach Series A.

• $150M Series A led by Felicis and UC Investments
• $250M total raised in 7 months
• 5M monthly users across 150 countries
• $30M ARR within 4 months of commercial launch

How it happened:
• Started as UC Berkeley "Chatbot Arena" research project (2023)
• Built crowdsourced AI model comparison platform
• Gained traction with model makers obsessing over rankings
• Partnered with OpenAI, Google, Anthropic for model access
• Launched commercial "AI Evaluations" service (Sept 2025)
• Hit $30M ARR in under 4 months

Takeaway: Academic research with real user traction can scale faster than pure startups when timing meets market need.
