Description

Overwatch, a New York-based startup founded in 2022 by Arjun Bisen and Zara Perumal, has closed a $15 million Series A round led by Mouro Capital with participation from Visa Ventures and Capit. The company develops AI-powered technologies to help enterprises defend against interconnected digital threats including cyberattacks, fraud, and financial crime. Bisen, a former Australian diplomat who shaped the country's cyber engagement strategy, argues that AI has fundamentally transformed cybercrime by making it faster, cheaper, and more coordinated. The funding will enable Overwatch to scale its digital threat detection platform as organizations face increasingly sophisticated, AI-assisted attacks.
