About
Sublime Security is a Washington D.C.-based AI-powered email security platform — backed with $240+ million in total funding including a $150 million Series C in November 2025 led by Georgian with Avenir and 01A — providing enterprise security teams with adaptive email threat detection and autonomous AI agents that protect organizations from phishing, business email compromise (BEC), and advanced email-based attacks. The platform's two autonomous AI agents — ASA (Autonomous Security Analyst) that investigates and triages threats in seconds, and ADÉ (Autonomous Detection Engineer) that deploys tailored detection rules for novel threats in hours — drove 100% ARR growth in the first half of 2025 with 100% enterprise customer retention since inception. Serving Spotify, Snowflake, Zscaler, Anduril, and SentinelOne, Sublime is built on a detection-as-code philosophy using MQL (Message Query Language) for auditable, customizable detection rules. Founded in 2019 by Josh Kamdjou (10 years DoD and private sector red team, where phishing was consistently the fastest network access vector) and Ian Thiel.
