BreachRx

BreachRx is a San Francisco-based SaaS company that pioneered Cybersecurity Incident Response Management (CIRM) - treating a breach as an enterprise-wide business crisis rather than a purely technical problem. Its Rex Platform gives security, legal, communications, and executive teams a single secure workspace to coordinate response, automatically track regulatory reporting obligations, and preserve a defensible audit trail. Founded in 2017 by Andy Lunsford and Matt Hartley, the company raised a $15M Series A in 2025 and serves 100+ customers including Coinbase, American Express, and Commvault.
