Cardinal — Startup ProfileAI Platform for Precision OutboundHQ: San Francisco, CA, United States | Founded: 2025 | Employees: 2-10 | Stage: Seed | Website: https://trycardinal.aiAboutCardinal is the AI platform for precision outbound. We run outbound for 40+ YC companies, including Mintlify, Greptile, and Luminai. 'Spray and pray' outbound is dead. The best sales teams operate with extreme precision—finding things in common with customers, monitoring their content, mapping inbound signals, and tracking website visitors. But doing this well means stringing together 10+ tools and hiring a GTM engineer. Cardinal replaces all of that. Our AI agents find hyper-targeted leads, continuously monitor what prospects are posting and engaging with on social media, generate personalized snippets based on shared context, and orchestrate end-to-end outbound workflows across email and LinkedIn.Key Metrics
