Product Lead

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 hiring a Product Lead to own and build out one of our most strategically important product areas from the ground up.

This isn't a traditional PM role. We're looking for someone who thinks and operates like a founder — someone who will take full ownership of a product area, drive it to product-market fit, and create the commercial momentum to get it to its first million in revenue.

You'll be the connective tissue across GTM, engineering, design, customer success, and external stakeholders. You'll go deep on customer problems, set the strategic direction, and move with pace and urgency to make it happen.

We're looking for a hyper-ambitious builder with sharp product instincts, first-principles thinking, and the commercial chops to put themselves in front of senior enterprise stakeholders and win.

🧱 What You'll Do

Own Your Product Area End-to-End

• Take full ownership of a core product area (e.g. Accounts Receivable) — from strategy through to delivery and commercial outcomes

• Define product vision and roadmap grounded in deep customer insight and first-principles thinking

• Drive urgency and business impact, with a clear line of sight to product-market fit and revenue

• Set the direction, prioritise ruthlessly, and hold the bar high across everything you touch

Be the Founder of Your Product

• Think and operate like a co-founder: take initiative, unblock yourself, and own outcomes regardless of what's in your job spec

• Build selling processes and GTM motion around your product area from scratch

• Put yourself in front of senior enterprise stakeholders — run the meetings, bring the narrative, and close the loop

• Work through ambiguity and complexity, breaking hard problems into clear, actionable pieces

Connect the Company Around Your Product

• Act as the hub connecting engineering, design, GTM, CS, and external domain experts

• Partner closely with engineering to define what to build and why — without needing to be managed

• Bring structure, focus, and pace to a cross-functional team working on something genuinely new

• Create alignment and energy across the organisation around your product area

Drive Customer Obsession

• Get deep on customer problems: uncover insights, challenge assumptions, and keep the customer at the centre of every decision

• Build relationships with customers and domain experts who can sharpen your thinking

• Translate complex workflow challenges into elegant, scalable product solutions

🧩 What You Need

• A genuine builder mindset — high ownership, relentless follow-through, and a track record of creating things from scratch

• Strong product fundamentals: you know how to uncover customer insights, translate them into strategy, and ship products people actually use

• First-principles thinking: you break problems down to their roots, challenge the status quo, and bring clarity to complex challenges

• B2B chops: you're comfortable in front of enterprise stakeholders — you can run a senior meeting, build a narrative, and command the room

• Evidence of zero-to-one experience — whether founding your own company, building a product area early at a high-growth startup, or launching something new inside a larger business

• STEM degree (or equivalent intellectual horsepower demonstrated through your work)

• The ambition and hunger to operate at a pace most environments don't allow

🌟 Bonus points if you have:

• Experience building in fintech, accounting, or enterprise finance software

• Prior founding experience or time at YC-backed / top-tier VC-backed startups

• Product experience at a commercially-driven, high-bar company like Stripe, Plaid, or similar

🚀 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 that is scaling rapidly, 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 🎶
