Hummingbird Ventures is an agile investor in entrepreneurial genius. We value emotional intelligence as much as data, growing internal culture as much as growing revenue, and forming strong, personal bonds with founders. Often the first institutional investor, we’ve helped start-ups scale from zero to category-defining multi-billion dollar businesses across 3 continents. We work best with outsiders who challenge industry boundaries and conventions, transforming tiny miracles into impactful companies. Hummingbird Ventures teamed up with transformative companies, including Deliveroo, Showpad, Kraken, Peak Games, Amplidata, Gram Games, Shutl, Merlin, Billiontoone and many others.

After winning the Airbus Entrepreneurship Prize 2018, we decided to make our idea a real business and change the energy world for the better. Greenvest is an energy start-up that aims to apply artificial intelligence to satellite data in order to develop optimal renewable energy solutions for regional deployments. Our company prides itself in its analysis and optimization of the deployment of renewable energy infrastructures.
