About Abnormal AI
Behavioral-AI threat protection platform that uses artificial intelligence to prevent email attacks and business email compromise. Its latest primary round, a $250M Series D, closed in August 2024 at a $5.1B valuation; annual recurring revenue has surpassed $200M, growing over 100%.
Abnormal AI is a behavioral cybersecurity platform that protects corporate email and user accounts, founded in April 2018 in San Francisco. The system builds a behavioral profile of every employee and business contact, and stops what looks normal to an email gateway but abnormal for that specific person. More than 4,500 organizations use the platform, including over 25% of the Fortune 500; annual revenue exceeds $200M growing more than 100% year over year, with 99% subscription renewals. Current valuation is $5.1B (August 2024, a $250M Series D), with roughly $520M raised in total. In August 2026 the company moved beyond email, launching account protection, corporate AI governance, and candidate screening; it holds GovRAMP and FedRAMP Moderate authorizations.

Key highlights
- The valuation has barely moved in almost two years while the business grew several times over. The last deal closed in August 2024 at a $5.1B valuation; since then the customer base has grown from 2,400 organizations to 4,500, and the Fortune 500 share has risen from 17% to more than 25%.
- Attackers have moved to artificial intelligence, and that breaks the old defenses. By the company's April 2026 report, the number of sophisticated attacks passing through traditional email gateways grew 97% in half a year.
- The company stopped being a single-product business exactly now. August 2026 opens sales of three new products — account protection, corporate AI governance, and candidate screening — plus an app store with one-click integration.
- Industry recognition is settled and government authorizations are in hand. The company has been a Gartner Magic Quadrant leader two years running and on CNBC's Disruptor 50 list for a third year; in 2025-2026 it obtained GovRAMP, FedRAMP Moderate, and ISO 42001 certification.
- The hiring reads like preparation for public markets. In April 2026 John Slavitt became general counsel, having led legal for twenty years at publicly traded Check Point Software and, before that, served as chief legal officer of Gong.
