Cardinal

@mit @trycardinalai

Cardinal is an AI platform for precision outbound aimed at B2B sales and go-to-market teams who want to run outreach, follow-up, research, scheduling, and CRM syncing through configurable agents rather than a stack of point tools. The workflow starts with defining a target list, then deploying revenue agents that each run a distinct motion, plugging in data to see what is landing and with whom, and doubling down on what works . The pitch behind this launch is that as products get easier to build, the durable edge shifts to how teams sell, and the fastest-growing companies are the ones already putting agents to work on real sales tasks instead of experimenting around the edges. The company launches with a real customer base rather than a waitlist. Its site lists 40+ YC companies including Mintlify, Greptile, and Luminai running outbound on the platform, and the launch tweet adds Deepgram and Giga to that group. The stated philosophy is that generic "spray and pray" sequences are burning out, and that precision, finding common ground with prospects, tracking their content, and routing signals from website visits, product signups, and ad impressions into the right sequences, is what actually books meetings now. Cardinal is built by Devi Jha and Jianna Liu, founders based in San Francisco , who are 2x YC founders (S23, W26) and Harvard/MIT CS alums . Their previous company, Leafpress, was an energy software company where they closed customers like Lindt and Honeywell from cold outbound , experience that shows up directly in how the product is designed for founder-led sales motions before a full GTM team is in place.
