Summary List PlacementA rolodex of Silicon Valley contacts is key to picking top European startups, according to an early-stage investor who backed three unicorns going public this year. Hussein Kanji is a partner at London-based venture capital firm Hoxton Ventures, which was founded in 2013 and wrote early checks for food-delivery firm Deliveroo, cybersecurity company Darktrace, and health-tech startup Babylon. It's a potential return that bigger operators in Europe could be proud of. Deliveroo and Darktrace completed multibillion-dollar IPOs in London this year, while Babylon has unveiled its intention to list through a $4.2 billion SPAC deal in the US.
