Cardinal: AI Platform for Precision Outbound

Powering outbound for 40+ YC companies.

The Problem

"Spray and Pray" outbound is dead. The best teams at outbound do it with extreme precision. Finding things in common with your customers, staying in touch with them through their content, mapping inbound from signups and ads, tracking website visitors, monitoring various signals—this sounds great in theory, but in reality involves stringing together 10+ tools and hiring a GTM engineer.

What You Can Do with Cardinal

Cardinal is an AI platform for precision outbound. Its agents can create workflows that normally require the work of fulltime GTM engineers.

• Find the perfect leads: Whether you need to map your entire TAM, enrich folks going to a conference, invite leads to a dinner you're hosting, or more, Cardinal finds the most precise leads for you to reach out to.
• Monitor content from your customers: Agents continuously track what your prospects are posting, sharing, and engaging with on social media, so you can stay up to date on what they are doing.
• Snippets that write themselves: Cardinal generates hyper-specific snippets based on things you and your team have in common with your customers.
• Build full workflows: Design end-to-end outbound workflows across email and LinkedIn.
• Capture inbound too: Set up website visitors, product signups, social media likes and comments, ad impressions, and more—qualify it and add them to your sequences.
