The company runs security assessments and red-team evaluations against advanced frontier AI models, works to set security standards for the frontier AI industry, and is trusted by major AI labs to evaluate model risk. Irregular raised $80M co-led by Sequoia Capital and Redpoint Ventures at a $450M valuation.
