Founding Product Growth
Briefcase
Why this role matters
We’re growing incredibly quickly. Today we work with 75+ UK-based accounting firms and serve thousands of their clients. Demand for Briefcase is outpacing what our small team can handle.
That’s where you come in. As Founding Product Growth, you’ll sit at the intersection of growth, sales and product. You’ll be part of a small, ambitious team obsessed with execution - helping us scale every part of the business while keeping us close to our customers.
What you’ll do
🚀 Marketing & Growth → You’ll build our go-to-market motion from scratch, experimenting with new channels and refining our pitch.
🤝 Full-stack Sales & CS → You’ll be doing outbound, demoing the product, closing deals, onboarding, customer success and upselling.
🤖 Product → You’ll gather customer feedback, influence roadmap decisions and ship improvements yourself (everyone codes at Briefcase, including non-technical people - don’t worry if you haven’t written code before, we’ll show you how).
About you
- You’ve consistently outperformed your peers
- You thrive in highly autonomous environments and like to own projects end-to-end
- You learn fast and are passionate about exploring new domains and technologies
- You’re commercially minded and excited to own the full customer journey
- You are product minded and enjoy problem solving from first principles
- You thrive in high pace environments, have a strong bias to action, and a high bar for quality
This is a unique opportunity to play a key role in shaping our GTM motion while influencing the product direction of a generational company.
