Investing
I have been investing in early-stage companies for over ten years across the United Kingdom, Europe and New Zealand. What began as backing interesting ideas has gradually become a more focused interest in a few sectors and a more active role in supporting the companies I believe in.
FintechClimateHealthEducationAI-enabled platforms
Early investments were driven by broad curiosity across products, founders and markets.
Over time, my focus has been on improving outcomes for people and the planet: fintech, climate, health and education.
The next phase is more active participation through follow-on investment, practical support and deeper involvement where there is strong conviction.
Advisory

Advisory

Fractional and Interim Leadership
