Harvey has announced its acquisition of San Francisco-based Guardrails AI, an AI security platform for agents. Guardrails is a pioneer of AI reliability and simulation infrastructure, creating the first open-source AI guardrails that help teams find where their agents stray from intended behavior and manage agent risk in real time. Guardrails’ co-founders, Shreya Rajpal and Zayd Simjee, and their team will join Harvey’s product and engineering organization. This marks Harvey’s fourth acquisition of 2026.
Latham & Watkins LLP advised Harvey in the transaction with a corporate team led by partners Tessa Bernhardt, with associates Tim Plummer and Min Oh; and an Emerging Companies & Growth team led by partner Alex Kassai, with associates Tori Hu and Rachel Oh. Advice was also provided on executive compensation, employment, and benefits matters by partner Maj Vaseghi, with associate Jennifer Lin; and on tax matters by Bay Area partner Grace Lee.
