wisetax.frInvestment thesis
Impact where the economics work.
1
Early stage
Pre-seed and seed, occasionally a first follow-on. We are comfortable before the metrics are clean.
2
Real-world impact
Health outcomes, resource efficiency, ageing well, waste reduction — measurable effects, not labels.
3
Technology with a moat
Deep tech, proprietary processes or applied AI where the product is hard to copy.
4
European roots
France and neighbouring markets, with teams we can meet in person.
How we work
Patient capital
No fund lifetime, no forced exit. We can wait for the right milestone and re-invest when it counts.
Operating experience
We have built companies ourselves — hiring, industrialisation, first commercial contracts, financing rounds.
An open network
Introductions to customers, co-investors, advisors and specialists across our sectors.
A fast, honest process
A first answer within days, a clear no when it is a no, and no surprises in the term sheet.
