We’re thrilled to announce that Summize has been named as one of Europe’s fastest-growing startups, ranking #157 in the Sifted 250 for 2025!

About the Sifted 250

Now in its second year, the Sifted 250 recognizes Europe’s fastest-growing startups by tracking their compound annual revenue growth over the last three financial years.

2025’s list includes 85 UK-based startups, more than any other country in Europe, with fintech and B2B SaaS being the leading sectors.

This year’s report shows a resilient and evolving startup landscape, with total revenues across the cohort increasing by 48% and average revenue per employee rising by 54%. The report also reveals a more efficient and resilient ecosystem, as companies are increasingly harnessing AI and automation to scale smartly.

This is the first time Summize appears on Sifted’s 250 European list. In March 2025, we made the Sifted Top 100 list for the UK and Ireland, so we’re thrilled to see our recognition on the continent too.

We’d like to extend our congratulations to the top three businesses on this year’s list – Finn, Yazen and tl;dv for their remarkable growth stories. We’re also proud to be in the company of other standout B2B innovators like Vertice, Nelly and Lindus Health, all of whom are helping shape the future of European tech.
