The 7 Newest Unicorns in June 2025

The end of the first half of 2025 saw a steady addition of startups to the unicorn hall of fame, with seven businesses earning the title in June. From AI tech companies to blockchain startups, these businesses are taking serious strides in terms of professional success, notoriety and financial valuation.

Becoming a unicorn is no easy feat, mind you. It requires not only reaching a valuation of at least $1 billion, but companies also need to be privately owned in order to qualify. Of course, $1 billion for a privately-owned (non-IPO’d) company is a lot of money, so getting to this milestone is a big deal.

Another factor to consider is that for many startups, June marks the close of the fiscal year, a key period when companies are assessed on performance, growth and investment potential. Securing unicorn status just before the year ends can offer a powerful signal to investors, stakeholders and the wider market, reflecting a company’s strength and momentum at a critical reporting juncture. It also places the startup in a stronger position when planning budgets, setting financial goals or raising additional funding for the new fiscal year starting in July.

In Europe’s competitive startup ecosystem, timing matters, and June is often a month when deals are finalised, funding rounds close and market activity peaks before the quieter summer months. Hitting a billion-dollar valuation during this window not only helps a startup stand out in end-of-year reports, but also sets the tone for future expansion, recruitment and partnerships. In short, becoming a unicorn in June carries both strategic and symbolic weight – a bold finish and an even bolder beginning.
