The best-funded generative AI startups in Europe have something in common: Big Tech experience

Most of the top-funded generative artificial intelligence companies in Europe were founded by entrepreneurs with experience at U.S. technology giants, according to a new report from venture capital firm Accel.

The report, produced in partnership with Dealroom, found a quarter of the 221 generative AI companies across Europe and Israel previously worked at Apple, Amazon, DeepMind, Meta, Google and Microsoft.

That figure rose to more than a third (38%) for the top 40 European and Israeli generative AI companies in terms of venture funding raised, and 60% for the top 10 generative AI companies for funding levels.

Harry Nelis, general partner at Accel, told CNBC tech giants are natural catalysts for new generative AI firms, as those companies "have been leaning forward in AI the most and … have the capabilities when it comes to compute, when it comes to data, when it comes to money."

"They are really smart in the sense that they have seen how an early lead in this field can lead to a massive competitive advantage," he said, adding there's a "golden opportunity" for people with "entrepreneurial mindsets" to make their own genAI ventures.

In its research, Accel defines generative AI as "an emerging AI frontier that uses models trained on a large data set of content medium ... to create something new instead of just analysing existing things."

Nelis noted many of the largest U.S. tech firms have already made early moves in AI — and Europe is an increasing focus.

Google bought British AI lab DeepMind in 2014, and the firm's tech is now key to AI products including its Gemini generative AI tools.

Meta, the parent company of Facebook, opened the European arm of Fair, or Facebook AI Research, in Paris in 2015.
