About Stef

If you're leading a business that wants to compete on values — not just price — I can help you make that real.

I work with UK B Corps, SMEs, and organisations serving public sector and regulated markets to turn ESG commitments and social purpose into genuine commercial advantage. That means strategy that wins tenders, business models built around impact, and governance frameworks that hold up to scrutiny.

My background spans 15+ years across the private sector, government, and international organisations. I've led B Corp transformations, SBTi-aligned decarbonisation strategies, and public sector go-to-market repositioning — including achieving perfect social value scores across 90% of tenders and contributing to £4m+ in new revenue.

I bring together organisational strategy, service design, and systems thinking. I work at senior level, and I'm comfortable advising Boards and Executive teams as well as rolling my sleeves up on delivery.

I typically work on: ESG and sustainability strategy (B Corp, Net Zero, SBTi, social value), corporate and business unit strategy, public sector go-to-market and procurement positioning, purpose-led transformation and change programmes, and service design and operating model redesign.
