Head of SME Growth in London

Flagstone is an online savings platform, reinventing how individuals, businesses, and charities manage, protect, and grow their cash. We are a diverse group of people, bound by a collaborative spirit and shared purpose, with a thriving, profitable business where smart people do their best work. Our unique culture is our pride and joy and competitive advantage.

To revolutionise the savings market, we need to be at our best. High performance takes more than talent; it takes a culture of kindness, respect, and growth. That’s why we’re building a diverse, inclusive community where your voice is heard and valued, and where you can surpass even your own expectations.

The Opportunity: Flagstone is the UK's leading cash savings platform, helping businesses and individuals put their money to work across a marketplace of banks and savings products. We manage over £19bn in Assets under Administration and are growing fast. Our SME Tribe is under 12 months old, sitting at £5bn in Assets under Administration, with a mandate to reach £15bn in under three years. This is a rare opportunity to be the primary commercial force behind one of the most significant growth ambitions in the business.

As Head of SME Growth, you will own full commercial leadership of the SME Tribe: driving client acquisition and activation, setting squad-level priorities, and taking direct accountability for performance against a £15bn AuA ambition. You will work in close partnership with the CGO, acting as the connective tissue between strategic direction and commercial execution.

What You'll Own

• Tribe Strategy & Commercial Ownership: Lead the SME Tribe across two squads focused on client acquisition and client activation, creating the conditions for high performance and scale. Own the commercial strategy for SME client acquisition and activation, translating a significant growth ambition into squad-level priorities and measurable outcomes. Define and own tribe OKRs, ensuring squad-level goals are clearly connected to Flagstone's broader growth targets and business strategy.
• Delivery & Performance: Drive the Tribe towards high performance — building ways of working, clarity of mission, and a culture of accountability and pace. Own the tribe roadmap across both squads, ensuring priorities are well-sequenced and dependencies are actively managed.
• People & Culture: Provide operational leadership to Squad Leads within the tribe, building their capability and holding them accountable for squad execution. Build a high-performance tribe culture — one that moves with pace, operates with discipline, and learns continuously.
• Cross-Functional Leadership & Proposition Influence: Partner closely with the Engagement Tribe to ensure the SME client experience extends beyond acquisition and activation. Act as the senior commercial sponsor for the SME proposition across Flagstone, ensuring that platform investment and propositional development across tribes reflects the needs and priorities of the SME customer.

• Experience leading squads or agile product/commercial teams in a digital environment.
