We’re working with a fast-growing AI start-up building an AI workforce for dental practices. They’re growing quickly and organically, adding hundreds of thousands in new ARR every month with no marketing or outbound spend. They’re now looking for an exceptional founding growth hire to work directly with the founder and scale the business to $10M ARR as fast as possible.

The role

This is a high-ownership, high-impact role where you’ll build the growth engine from the ground up. You’ll work side by side with the founder, learn to close, open new channels, and take on whatever moves the business forward. It’s ideal for an ambitious early-career seller who wants a founding role.

• Building growth channels: Launch outbound campaigns, develop partnerships and create repeatable customer acquisition systems.
• Moving fast and building: Use AI tools to build internal tools, automate workflows and remove operational bottlenecks.
• Driving distribution: Attend conferences, travel frequently, build relationships and find creative ways to win customers.
• Owning outcomes: Spot the highest-leverage opportunities and act on them without waiting for direction.
• Expanding into wider growth: Take on other areas as the business scales, such as events and marketing.

What our client is looking for

• Up to 3 years’ experience as an SDR or recently promoted AE at a tech start-up
• Experience building strong pipeline through cold calling and converting inbound leads
• B2B SaaS start-up experience, ideally at a YC or other top-VC-backed company
• Top-tier interpersonal skills: persuasive, confident and quick to build relationships
• High agency: resourceful, scrappy and able to work things out independently
• Technical aptitude: comfortable with AI tools, building lightweight software and automating processes
• A founder mentality and drive, plus comfort with ambiguity, intense ownership and frequent travel
• Clear signs of excellence, such as top rankings (#1 rep, top 5 in office), President’s Club, or in-person sales experience
• Previous founder experience running founder-led sales
