Vals AI Raises $40M Series A at $400M Valuation — AI Evaluation as Legal Infrastructure

Vals AI announced on August 13, 2026 a $40 million Series A at a $400 million valuation, led by Andreessen Horowitz (a16z), with participation from 8VC, Pear VC, BloombergBeta, HRT Ventures, and Next Ladder Ventures — bringing total funding to $45 million. Vals builds independent benchmarks and evaluations that measure how AI models perform on real-world professional tasks for lawyers, bankers, engineers, and doctors. The September 1 Legaltech.com Funds Flow report confirmed the round. The strategic signal is that the legal AI market has matured to the point where evaluation infrastructure is venture-scale: as firms and legal departments deploy multiple AI systems across practice areas, independent benchmarking and auditability of model performance has become a procurement requirement rather than a nice-to-have. For law firms building AI-native workflows, Vals addresses a critical governance gap — enabling systematic comparison of model outputs on real legal work before deployment.
