On September 17, 2025, Irregular (formerly known as Pattern Labs), an AI frontier security lab, announced that it has closed an $80 million round of Seed and Series A funding. The round was led by Sequoia Capital and Redpoint Ventures, with participation from Swish Ventures and angels such as Wiz Co founder and CEO Assaf Rappaport. Wilson Sonsini Goodrich & Rosati advised Irregular on the transaction.

The company runs controlled simulations on frontier AI models to test both their potential for misuse in cyber operations and their resilience when targeted by attackers. The company gives AI creators and deployers such as OpenAI, Anthropic, and Google DeepMind a secure way to uncover vulnerabilities early and build the safeguards needed. 

The Wilson Sonsini team that advised Irregular on the transaction included Mark Baudler, Lauren Lichtblau, Sunny Kumar, Peter Bratton, and Kate Secrest.
