Overview

Hey YC! We're Devi and Jianna - the founders of Cardinal.

Hey guys! We’re launching Cardinal publicly today - co’s like Mintlify, Deepgram, Giga, etc. use us to build revenue agents & design how they sell.

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, etc. This sounds great in theory, but in reality involves stringing together 10+ tools and hiring a GTM engineer.

That’s where Cardinal comes in.

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

If you're a founder or sales leader looking to bring AI into your sales org, would love to chat!
