Backing people who
move knowledge forward.
I invest my own capital, experience and network in early-stage companies that rethink how knowledge is created, shared and used.
Investment perspective
Founder first. Purposeful by design. Built for substance.
I am most useful where a strong idea meets a complex market. I look for founders with unusual insight, intellectual honesty and the resilience to turn a clear conviction into a real business.
Content & workflow
Tools and platforms that improve how expert content is created, evaluated, distributed and discovered.
Vertical B2B technology
Focused solutions for overlooked markets, built on genuine domain understanding and customer proximity.
How I work
Capital is useful. A candid conversation at the right moment can be just as valuable.
Early & engaged
I prefer to get involved when the product and the story are still taking shape.
Direct & constructive
Founders get an honest perspective, practical help and no unnecessary theatre.
Long-term minded
I value resilient companies, thoughtful growth and relationships built on trust.
A good fit
What I look for
My perspective is shaped by more than two decades in publishing, research and education — as a business leader, founder and investor.
- 01A founder with a distinctive insight
- 02A painful and well-understood customer problem
- 03A focused entry point into a meaningful market
- 04A product that gets stronger as its community grows
- 05A team open to debate, learning and change
Selected investments
A portfolio built around knowledge, workflow and focused technology.
I have invested across different stages and geographies. What connects these companies is a clear problem, strong domain insight and founders prepared to learn quickly.
