Funding Round Highlights

Irregular disclosed an $80 million financing round that was led by Sequoia Capital and Redpoint Ventures. Wiz CEO Assaf Rappaport also participated in the round, which values the company at $450 million. The investment is intended to expand Irregular’s capabilities in identifying and mitigating emergent risks associated with frontier AI models before they appear in real‑world deployments.

Company Evolution and Core Technology

Formerly operating as Pattern Labs, Irregular has become a prominent player in AI security evaluations. Its work is cited in security assessments for models such as Claude 3.7 Sonnet and OpenAI’s upcoming releases, including the o3 and o4‑mini models. Central to Irregular’s offering is the SOLVE framework, a scoring system that measures a model’s ability to detect vulnerabilities. The company also runs elaborate simulated network environments where AI agents act as both attackers and defenders, allowing the team to observe where defenses succeed or fail when new models are introduced.

Industry Context and Outlook

Co‑founder Dan Lahav noted that the coming wave of economic activity will revolve around human‑on‑AI and AI‑on‑AI interactions, which will stress existing security stacks. Co‑founder Omer Nevo added that Irregular’s simulations enable intensive testing of models before they are released, providing insight into potential security gaps. This focus aligns with broader industry movements, as major AI firms have upgraded internal security measures to guard against corporate espionage and the increasing ability of AI models to discover software vulnerabilities. The funding round positions Irregular to continue its mission of securing increasingly sophisticated frontier models, a challenge Lahav described as a “moving target” that will require ongoing effort.
