What our customers are saying
Devi and Jianna are the best! They have been helping us with full-stack outbound engine building + strategy. We just got started a couple of weeks ago and have been a joy getting to work with them (especially directly within Slack).
I’ve tried a couple of different options previously (agencies, AI SDR, myself, etc.), which didn’t work well. They were in my batch, and I love that I can interface with founders who just get it.

Cardinal has ran our outbound for almost 2 months now. Setting up sequences is super intuitive and its allowed us to 4x our outbound volume. The team also works fast to ship new features/bug fixes. Excited for the full launch!

Cardinal transformed our business! We met them during the YC batch, and setting up outbound with them immediately helped us talk to tons of customers, book over $70,000 in revenue, and was the jumpstart we needed.

We’ve loved working with the Cardinal team. We had tried email as a channel several times and always felt the overhead of setup and management was a big challenge. It’s been long overdue to take a service approach to this problem, and Devi and Jianna are crushing it 💪

Cardinal is literally game changing. We’ve been working with them for months, and are the No 1 driver of our top-of-funnel. The product is built for founder led sales, is far more straightforward than any other option, and yet is as powerful as a whole suite of 7 tools (list building and prospecting, email and Linkedin infra, drip campaign sequencing, etc. etc.)
Also, Devi and Jianna are a true joy to work with - they take extreme action on every bit of feedback and are shipping at an insane velocity. Feel extremely cared for as a customer.
