Cardinal
Revenue Agents for GTM teams
Founding AE
About the role
About Cardinal
Cardinal is building the AI platform for precision outbound.
We help the best companies run world-class sales — combining data, AI, and execution into one system that actually drives revenue.
- $1M ARR run rate in ~2 months
- ~80k MRR and growing fast
- Backed by Y Combinator
- Built by 2x YC founders (Harvard + MIT + Prod)
We’re moving fast, closing top customers, and becoming the default outbound stack for the best teams.
The Role
This is not a normal AE role.
You’re not just selling - you’re:
- Helping define how modern outbound works
- Working directly with customers to win deals using Cardinal
- Turning insights into repeatable playbooks
- Acting as a bridge between product, customers, and revenue
This role is core to the company.
Cardinal is a sales company - this role directly determines how fast we grow.
What You’ll Do
- Run full-cycle sales (from first touch → close)
- Work closely with customers to launch and optimize outbound campaigns
- Get customers to their first response fast (this is everything)
- Develop creative outbound strategies (not just templates)
- Turn successful campaigns into repeatable systems
- Push product forward with real customer feedback
- Close high-value deals and expand accounts
Who You Are
We’re looking for scrappy, high-agency sellers who love the craft.
You might be:
- A former founder
- Someone who scaled a startup early
- A top AE who hates doing things the “normal way”
- Someone who has run outbound themselves
You:
- Love working directly with customers
- Are extremely hands-on
- Can figure things out without being told
- Are creative with outbound (not just following playbooks)
- Want to win — and are willing to hustle for it
About Cardinal
Cardinal 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. Cardinal also captures inbound from website visitors, product signups, ad impressions, and social engagement — qualifying and routing them into sequences automatically.
Cardinal is founded by Devi and Jianna, 2x YC founders (S23, W26) and Harvard/MIT CS alums. Their last company, Leafpress, was an energy software company where they closed customers like Lindt and Honeywell from cold outbound.
