The Problem

Business email compromise (BEC) attacks cost $50B annually. Traditional email security relies on signatures and reputation — useless against novel, targeted attacks with no prior history.

The Solution

LLM-based semantic analysis of email intent combined with behavioral baselines for every sender-recipient pair, detecting manipulation tactics that signature-based tools miss entirely.

Traction

14 enterprise pilots, $180K ARR, 99.2% detection rate with 0.01% false positive rate

Target Customer

CFOs and CISOs at companies with high BEC exposure — financial services, legal, real estate, and healthcare
