Company Description

Abnormal AI is a cybersecurity company that provides an AI-native platform focused on human behavior security. The system analyzes business processes and communication patterns to detect and prevent sophisticated cyber-attacks, primarily targeting email and connected cloud applications. Its key products offer inbound email security, protection against account takeovers, and security posture management. Founded in 2018 by CEO Evan Reiser and CTO Sanjay Jeyakumar, the company was previously known as Abnormal Security. It has grown through multiple funding stages, including a Series A in 2019, Series B in 2020, Series C in 2022, and a $250 million Series D round in 2024.

The company is expanding its reach into the public sector after recently achieving GovRAMP Authorization, a move sponsored by The University of Texas at Austin that allows it to serve state, local, and education entities. Abnormal AI continues to develop its platform, with plans to introduce new features such as an AI Phishing Coach and AI Data Analyst. The effectiveness of its service has been highlighted by customers like Landmark Group, which reported preventing $1 million in vendor fraud losses and saving over 1,320 hours of manual work within the first year. The significant capital raised in its 2024 funding round is poised to support further product development and market expansion.
