When ChatGPT launched in November 2022, Evan Reiser’s first thought was how amazing the technology was. And then: “Oh, my God, the bad guys are going to get this too,” he recalls. Reiser cofounded Abnormal Security in 2018 with Sanjay Jeyakumar to help detect and prevent email cyberattacks. The company uses AI and machine learning for behavioral profiling, analyzing data from company platforms like Slack to help spot socially engineered email scams and determine whether messages were sent by an actual employee or by a hacker posing as one. Reiser says the explosion in popularity of ChatGPT and other chatbots has increased the sophistication of email attacks. But Abnormal is planning to be around for the long haul to combat them: Earlier this year, the firm integrated with workplace software including Slack, Zoom, and Microsoft Teams, and plans to add others, like Salesforce or ServiceNow. The company says its customers include 12% of Fortune 500 companies. And recently, the company announced it passed $100 million in annual recurring revenue. It’s also flush with funding: Abnormal has raised over $280 million from investors including Insight Partners, Greylock Partners, and Menlo Ventures, and is valued at $4 billion. Having teased IPO plans for years, Reiser says now the company is focusing on doing more to protect customers, and it could go public in a couple of years.
