Riverbank

Riverbank is a San Francisco, California-based cybersecurity company that develops AI-native red teaming and offensive security solutions for enterprise organizations. The platform targets the commercial penetration testing sector by deploying coordinated swarms of artificial intelligence agents alongside human operators to identify complex network vulnerabilities that standard automated security scanners do not detect. The organization utilizes the specialized background of its core team members, who previously served in high-level cyber operations at the National Security Agency (NSA) and the United States Department of Defense (DoD). Operating as an early-stage business-to-business enterprise software provider, Riverbank currently maintains an official employee count of one while actively developing its core technological infrastructure. The company is currently backed by Y Combinator as a participant in its upcoming Summer 2025 startup batch and was originally founded by former government intelligence professionals.
