Summary

Harvey said the round was co-led by Lightspeed and Diffusion and would support proprietary model development and enterprise expansion. The company also introduced a post-trained open-weight model and Harvey LAB benchmark, while reporting coverage said it acquired agent-security startup Guardrails AI.

Why it matters

Vertical AI companies are increasingly combining domain data, models, evaluations and security rather than relying entirely on general-purpose providers. Harvey’s valuation and customer penetration indicate how quickly specialised AI platforms are becoming strategic infrastructure for professional services.
