Job Description

Founder's Associate

Department: Account Management and Implementation

Employment Type: Full Time

Location: London, UK

We’re looking for a Founder’s Associate to join us. We need someone sharp, ambitious, and hungry to learn As a Founder’s Associate, you’ll report to our founder, and work directly with our CEO and leadership team on the financial, legal, and strategic priorities that drive the business forward.

You’ll be in the room where the biggest decisions are made. This role is varied and ever-changing: from building the financial models that guide our strategy, to managing the legal frameworks that keep us moving, to leading special projects that could shape the next phase of Stint’s growth.

We’re looking for someone with a background in i nvestment banking, consulting, or similarly fast-paced environments who’s ready to swap client decks for building an actual business. This is a high-exposure, high-impact role where you’ll wear many hats, learn at speed, and help scale a product that’s genuinely changing an industry.

We are an office-first, collaborative team and this role is based in Camden 5 days a week.

What you will be doing:

• Build and maintain the financial models that inform our fundraising, strategy, and growth decisions.
• Contribute to high-stakes projects like fundraising, due diligence and product partnerships providing the analytical backbone for success.
• Act as a trusted partner to the CEO and Chief of Staff, bringing clear, data-driven recommendations on critical initiatives.
• Foster alignment across departments to ensure operational efficiency as we scale.
• Support financial and legal operations – from contracts and compliance filings to working with external counsel.
• Embrace the scrappy startup mindset: hands-on, fast-moving, and unafraid to dive into challenges big or small.
• Help shape and champion Stint’s startup culture of transparency, fast-pace and ambition.

This position might suit you, if:

• You’ve got an entrepreneurial mindset - curious, proactive, and motivated by building something new from the ground up.
• You thrive in fast-moving, ever-changing environments, and see ambiguity as an opportunity rather than a blocker.
• You have 1+ years of experience in investment banking, consulting, private equity, or a similar role, ideally with exposure to startups or high-growth environments.
• You’re fluent in financial modelling and analysis, and you know how to translate numbers into clear, strategic decisions.
• You can run with big responsibilities autonomously, prioritising what matters most and delivering quickly without dropping the detail.
• You’re a clear communicator who can break down complex problems and get buy-in from different stakeholders.
• You will be comfortable with the basics of legal and compliance for scaling companies, and aren’t fazed by contracts or filings.

What we can offer you:

• Private medical insurance
• A social, friendly and welcoming team based in the heart of Camden
• Office gym membership
• Ownership shares in a well-funded, growing start-up
• Dog friendly office!
• Free office fruit and snacks
• Office dinner if working late
• Regular office breakfasts and lunches
