Job description

This role is based out of our London office
We are an office-first company & believe great products are made when we are together.

About Stacks

Stacks is building an AI-native platform that reinvents how modern finance teams run the monthly close. The opportunity is massive: every growing company depends on accurate, timely financial data, yet most are still operating with tools and workflows built for a different era.

In just two years, we’ve grown from a team of 2 to 30+ and are on a rapid trajectory. We’ve raised a $23m Series A led by Lightspeed Venture Partners, and we were recently recognised as one of Harmonic’s Hottest Startups of 2026.

We’re already trusted by leading European scale-ups including Pleo, Freetrade, and Motorway. Our team is a blend of finance, product, and technical experts from top-tier companies like Uber, Plaid, Miro, Mollie, and Bunq, united by the drive to create a game-changing solution.

We’re a team that is deeply customer-obsessed, plays to win, and isn’t afraid to take big, bold bets. We move fast, hold a high bar, and are committed to growing together as we scale.

About the Role

Stacks is looking for a fiercely ambitious, entrepreneurial, and commercially driven Business Development Representative / Commercial Associate to join as one of our initial GTM hires!

In this high-impact role, you’ll collaborate closely with our Sales team to create and execute our GTM strategy at Stacks. If you’re excited by the idea of limitless growth and fast-paced challenges, this is a unique opportunity to accelerate your career as you help shape the future of Stacks.

What You'll Do

• Prospecting & Pipeline Generation: Own outbound into Mid-Market and Enterprise companies across the UK.
• Outbound Strategy: Run multi-channel campaigns across email, phone, and LinkedIn. You'll be writing, testing, and iterating constantly.
• Discovery & Qualification: Hold sharp, insight-led conversations with finance leaders. Your consulting instincts for asking the right questions will show up here.
• Product Mastery: Get deep on the close process fast, so you can speak credibly about debits, credits, reconciliations, and the pain of a 10-day close.
• Cross-functional Partnership: Work directly with our Sales team to shape messaging and build a repeatable outbound motion.
• Growth Path: Clear track to AE. This is the launchpad role. You're looking at an 8-12 month trajectory into a mid-market deal-making role.

What You Need

• Brilliant Background: 1–3 years in a top-tier environment like MBB, VC, PE or Early-stage
• Analytical Horsepower: You think in frameworks, get to the "so what" quickly, and can break down a prospect's business in a first call.
• Commercial Instinct: You want to be closer to revenue. You're motivated by tangible, measurable outcomes, not slide decks read by three people.
• Hunger & Grit: You're competitive, coachable, and don't flinch at a cold call.
• Clear Communicator: Written, spoken, and on the phone, you can be concise, direct, and persuasive.

What’s in It for You

• Foundational role: Help shape a category-defining company from an early stage, working directly with founders and a small, high-agency team.
• Meaningful ownership: Competitive equity in a company scaling rapidly towards $10m ARR, where your impact will directly shape the outcome.
• Cutting-edge product and tech: Work at the intersection of AI and finance, building systems that fundamentally change how companies run their financial close.
• High-calibre team: Collaborate with people from companies like Uber, Plaid, Miro, and Mollie.
• Exceptional workspace: Our London HQ is based in Fora — a modern, design-led space in the heart of the city with access to a gym, classes, and an environment built for focused, in-person building
• Strong team culture: We run regular socials and off-sites that bring the team together properly, we recently have our 2-year anniversary party in Amsterdam, with board games, a tarot card reader and live music

• Solutions Engineer: Run technical discovery and demo behind the close.
• BD Lead: Hire and coach the next wave of BDRs as the team scales.
• Product: Shape what we build with everything you hear on the front line.
