When it comes to deep tech, from AI to big data and AR, Europe is neck and neck with Asia and Silicon Valley.

European deep-tech start-ups demonstrate the best opportunities for scaling up.

And, according to the recent State of European Tech report, Europe’s tech industry is growing five times faster than the rest of the European economy in terms of gross value added, a level that has accelerated in recent years.

Last year, our Europe Start-up 100 2018 list looked at various players demonstrating how Europe is gathering momentum in areas such as artificial intelligence (AI), autonomous vehicles (AVs), augmented reality (AR), virtual reality (VR), robotics, big data and more.

This listing is part of our Europe Start-up 100 series for 2019, which every day this week is focusing on a different list, including fintech and e-commerce, hardware and the internet of things (IoT), and medtech and life sciences start-ups. On Friday (25 January), we will publish our full Europe Start-up 100 list of the ones to watch.

Remember, these lists are not absolute because they are only a dip in the ocean of European innovation. As such, they are devised to give you a flavour of the kind of activity that is happening.

And so, in the realm of deep tech, here are 25 European start-ups to watch in 2019.
