AI Benchmarking Startup Vals Raises $40M Series A
Vals, a startup founded in 2024, aims to become the gold standard for AI benchmarking. The company has raised a $40 million Series A led by Andreessen Horowitz, following a seed round led by 8VC and Bloomberg Beta. Vals differentiates itself by keeping its test materials private to prevent companies from gaming the system, and by evaluating models on industry-specific tasks in law, finance, and coding, as well as emerging areas like cybersecurity and biosecurity. The company's revenue is eight times what it was last year, and its team has grown from eight to 25 employees. Vals also launched a program to provide model evaluations to federal agencies. Founder Rayan Krishnan believes that as AI companies go public, rigorous benchmarking will become essential for public trust and corporate governance.
