Kees Jan Koster

Technology advisor for impact investors and their portfolios

Kees Jan Koster works at the intersection of technology and impact: helping investors make better decisions, and helping funded projects and organisations actually build what they set out to build.

On the investor side, he provides independent technical due diligence for venture capital and impact funds, family offices, and philanthropic investors: assessing software viability, evaluating technical teams, and pressure-testing roadmaps before capital is committed.

On the portfolio side, he provides post-investment technical support and capacity building, working directly with funded companies and impact projects to strengthen their technology, close capability gaps, and deliver on their original promise.

Known for his independent and transparent approach, Kees Jan works on high-impact, short-term engagements: the expert perspective you need, without the overhead of a full-time hire.
