Profile

We partner with founders starting out, and established teams scaling their growth. We have raised €487m across multiple funds to support this goal. We invest for the long term. Our investments span technology sectors and investment stages ranging from seed to growth.

We look for companies with potentially cutting-edge, category-defining businesses in very large markets. We help founders build and scale leveraging the experience of backing over 200 founders before.

The teams and companies we back scale their investor base as they scale their business execution and ambition. We work closely with them in this process. Over the past 25 years have built a broad network of US and European VC firms that share our vision and approach.
