The 12 European tech startups that are most likely to be worth $1 billion next

Roughly three European tech companies a year have been sold or floated on the stock exchange, or otherwise valued by investors, at $1 billion or more since 2000, according to $4.

But in the last 12 months, Europe has $4 to its list of "unicorns." GP Bullhound's report also sets out which tech firms are likely to see reach billion-dollar valuations next.

Food delivery startup HelloFresh made it onto $4 and has already reached billion-dollar status. German credit scoring firm Kreditech, which has just raised another $92 million in Series C funding, could be next.
