Founding Account Executive, UK

About Solvimon

Solvimon is a payments-native, billing and metering platform built for modern and AI-native pricing models. We cover the full quote-to-cash lifecycle: CPQ, usage metering, wallets and credits, payment orchestration and e-invoicing. Our founders previously built Adyen's internal billing engine, and we're backed by Northzone.

We're a team of around 20 based in Utrecht, working with fintech, marketplace, SaaS and AI companies across Europe. The UK is one of the most important markets for what we do, and we want someone on the ground in London to own it.

About the role

As our first sales hire in the UK, you'll own the full sales cycle: finding the right accounts, running discovery with finance, product and engineering leaders, shaping commercial proposals and closing. You'll work directly with the founders, and what you learn in the market will shape our positioning, pricing and product roadmap.

This is a builder role. There's no existing UK playbook, pipeline or team to lean on yet, so you'll create them. Do it well and you'll be the person who grows the UK team.

What you'll do

• Own UK new business end to end, from outbound prospecting and events to negotiation and signature.

• Build and run a pipeline of scale-ups and enterprises with complex billing needs: usage-based and hybrid pricing, multi-entity, multi-currency and multi-PSP setups.

• Run consultative, multi-stakeholder deals with CFOs, Heads of Finance, CPOs and CTOs, often replacing in-house billing systems or legacy tools.

• Partner with our product and engineering team on demos, proofs of concept and RFPs.

• Build relationships with PSPs, consultancies and systems integrators in the UK ecosystem.

• Represent Solvimon in the London fintech and SaaS community.

• Bring market feedback back to the founders and product team, and help define our UK go-to-market playbook.

About you

• You have 5+ years of B2B SaaS closing experience, ideally selling technical, infrastructure-level products (billing, payments, fintech, data or developer tools).

• You have a track record of hitting and beating quota on complex, six-figure deals with long sales cycles and multiple stakeholders.

• You've worked at an early-stage company, or opened a new market, and you're comfortable building from zero.

• You know the UK fintech, SaaS or AI scene and have a network to match.

• You're commercially sharp and curious about technology. You can talk pricing strategy with a CFO and API architecture with a CTO.

• You're self-directed and happy working as the first person in a location, with regular trips to our team in Utrecht.

• You have the right to work in the UK.

Nice to have

• Experience selling billing, payments, revenue or finance-ops software (for example PSPs, billing platforms or ERP-adjacent tools).

• An understanding of usage-based and AI-native pricing models.

• Experience with partner or channel sales.

What we offer

• A founding role with real ownership of the UK market and a direct line to the founders.

• Competitive base salary, commission and equity.

• The chance to build and lead the UK team as we grow.

• A product that solves a problem every scaling company runs into, in a market being reshaped by AI and usage-based pricing.

• A small, ambitious team with deep payments and billing expertise.
