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!

I've learned so much about outbound from this amazing team. They help with every step of the process. Like having a dedicated team of professional outbound consultants on your team.

Using cardinal has allowed our small team to automate outbound giving us more time to work on product. I've used it to warm my LinkedIn, send hundreds of emails, and find people in our ICP group. Highly recommend!

Cardinal’s been running all our outbound end to end. i tell them who we want to target and they handle the rest, plus i get a portal to respond to replies from all sources, stay on top of threads, and keep everything moving. i chat with the founders every week and it genuinely feels like having a fullstack outbound team on demand

"Easily the best outbound automation I've used"

Working with Cardinal feels like having an elite outbound team sitting right in your Slack.
Their speed of execution is insane, whether it’s tweaking copy, implementing sequences, or pivoting our lead list to hit higher-level executives. We’re already seeing the momentum with multiple meetings on the calendar from big-name accounts. It’s rare to find a team that is this responsive and tactically helpful.

We’ve launched precise outbound sequences that would have taken us 10 tools and an engineer to do without Cardinal. Cardinal is the new way to GTM.

Devi and Jianna have built a tool that allows me to snipe the perfect contact at an enterprise in just a few minutes. It’s one of the best AI tools I’ve used.

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.

Devi and Jianna are the best! Been working with them for a couple of months now and am incredibly impressed with the results. Previously, our outbound via email and LinkedIn was distributed across several tools, but having it consolidated in one platform has been valuable.

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.
