Early conviction, held for the long run.
We lead seed and Series A rounds for technical founders in Europe and North America, and stay with them through every round that follows.
A small partnership, built for the long climb.
Six partners, one fund at a time, and a handful of new companies a year, so every founder works with the person who made the decision to back them.

Essays
The case for the long first cheque
Why we write fewer, larger first cheques, hold back more than half of each fund for follow-ons, and accept the slower pace that comes with both.
