About Overwatch Data
Arjun Bisen and Zara Perumal spent their careers inside the problem at Stripe, Google and Twitter. Overwatch is the system they wanted when they were the ones holding the line.
Why we built this
At Stripe, Google and Twitter, we worked on the teams that sit between attackers and the business. The job was always the same: find the signal, investigate it, decide. Every year the volume went up and the team stayed the same size.
Then attackers started using AI. A convincing phishing email went from a day's work to a few minutes. No amount of hiring keeps pace with that, so we set out to build a system that could.
Overwatch runs cyber, fraud, brand and merchant risk on one system. AI agents handle collection and the first pass of every investigation. Our analysts take the hard cases and teach the agents what to look for next. Every customer's detections make the platform sharper for the rest.
We’ve raised a $15 million Series A, led by Mouro Capital with Visa Ventures and Capital One Ventures. It lets us extend our agents across more of the risk lifecycle, from monitoring and investigations in the criminal underground to merchant onboarding and due diligence, and grow the team across engineering, investigations and sales.
