About Cardinal

Cardinal is an AI-powered outbound and go-to-market platform founded by Devi Jha and Jianna Liu, both experienced entrepreneurs who have previously built and sold a company to Johnson Controls and participated in Y Combinator twice. Based in San Francisco, Cardinal operates as a small, founder-led team that works in-person five days a week, combining deep technical expertise—Jha studied computer science at Harvard while Liu is an MIT CS graduate with prior experience at Meta, Nvidia, and DoorDash—with a commitment to building enterprise-grade infrastructure. The company has constructed its platform on multi-tenant infrastructure with SOC 2-ready audit logging, positioning it to serve demanding enterprise customers from the ground up.
