Irregular Secures $80M to Advance AI Security and Model Risk Evaluation
By James Dargan · · 1 min read
Irregular, an AI security company formerly known as Pattern Labs, has secured $80 million in new funding in a round led by Sequoia Capital and Redpoint Ventures, with participation from Wiz CEO Assaf Rappaport. The funding values the company at $450 million.
Irregular has become a key player in model risk evaluation, with its frameworks cited in security assessments for Claude 3.7 Sonnet and OpenAI’s o3 and o4-mini models. Its SOLVE scoring system is widely adopted to measure models’ vulnerability-detection capabilities.
The company is expanding beyond analyzing existing risks to predicting emergent behaviors through simulated environments, where AI systems act as both attacker and defender. The investment will accelerate its mission to safeguard increasingly powerful AI models.
