Each year, Viva Technology publishes its "Top 100 Next Unicorns", a list of the 100 most promising scaleups in Europe. Those named are fast-growing tech companies with the potential to reach a valuation of $1 billion or more in the near future. So far, a third of the companies on VivaTech's top list for 2019 to 2023 have already become unicorns. One notable example is Pennylane, last year's winner in the FinTech category, which has achieved unicorn status this year.
