About Lunos
Most B2B companies are owed millions and chase it with spreadsheets, sticky notes and politely worded reminder emails. The money is sitting right there, trapped, while finance teams burn nights and weekends trying to pull it in by hand. We think that is a job for an agent, not a person.
Lunos started with the AI partner for accounts receivable. Our first agent ran collections the way an experienced AR pro would, only it never sleeps, never forgets a follow-up and gets sharper with every invoice. Finance leaders choose how much rope to give it through autonomy modes: Monitor, Suggest or Act. We’re building an agent-to-agent network for B2B payments, where the buyer's and seller's AIs settle invoices between themselves.
We are headquartered in New York and backed by General Catalyst and Cherry Ventures, plus angels including current and former CFOs from the likes of Eli Lilly and Deliveroo. Our founder Duncan Barrigan was Chief Product Officer at GoCardless, where he spent a decade building a $2.2bn B2B payments company..
Our values are simple and we mean them: we are curious, courageous and relentless.
About the role
This is the founding SDR hire. You will be one of the first people whose full-time job is to find the companies that need Lunos and get them in the room. You will report to our Head of Growth and work shoulder to shoulder with the team on the outbound engine that takes us from early traction to real scale.
Here is the part most SDR roles cannot offer. You will sell an AI agent, and you will use AI to do your own job. We are AI-native inside the building, not just in the product. You will research accounts, personalize at volume and run more outreach experiments in a week than a traditional SDR runs in a month, because the busywork is handled by tooling instead of by you. The SDR role is changing fast. Here you get to be on the front edge of what it becomes rather than the version that is being automated away.
You will be talking to CFOs, Controllers and Heads of AR at midmarket B2B companies who are quietly losing money to a broken process. Your job is to make them feel that pain clearly and show them there is a better way.
What you'll do
- Build pipeline through every channel that works: LinkedIn, email, phone, events and community. We care about booked, qualified meetings, not activity for its own sake.
- Become genuinely expert in receivables, the B2B cash cycle and how the Lunos agent changes the math for a finance team.
- Use our AI tooling to research target accounts, tailor outreach to each prospect and test messaging at a pace a manual SDR cannot match.
- Partner with growth and the founder to write, test and sharpen the outbound playbook from close to scratch. What you learn becomes how we sell.
- Hand the founding sales team a steady flow of high-quality, qualified opportunities.
- Bring the field back inside. You will hear the real objections and buying signals first, and we want you shaping strategy with them.
What we're looking for
We care more about drive and raw ability than a specific resume. Prior SDR experience is a plus, not a requirement.
- A relentless and sharp communicator in writing and on the phone who can make a busy CFO stop scrolling.
- Organized and calm under a high volume of activity, with a real instinct for priorities.
- Hungry to build a sales career and energized rather than rattled by a pre-seed startup that is still figuring things out.
- Curious by default. You want to understand finance, the buyer and the product, not just read a script.
- Comfortable with AI tools and excited to push them further. If your first instinct is "can software do this for me", you will fit right in.
- Tenacious. You follow up, you stay in the game and you do not take a quiet inbox personally.
- Bonus points for exposure to B2B SaaS, fintech or finance buyers.
Compensation and benefits
- Compensation: Base salary of $60-75K plus uncapped commission, for on-target earnings of roughly $95-115K. Final offer depends on experience.
- Equity: Meaningful early-stage equity. You are a founding commercial hire and you will own a real piece of the upside.
- Growth: A clear path to Account Executive, typically within 6 months for people who hit their numbers.
- Flexibility: Hybrid model based out of our New York office, balancing in-person momentum with room to breathe.
- Culture: A small, ambitious team that ships, backed by serious investors and a founder who has built in this space before.
