Product Lead

This role is based out of our London office

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.

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

• 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

• 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 a modern, design led space in the heart of the city with 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. We recently celebrated our 2 year anniversary in Amsterdam, with board games and live music.
