Europe’s 10 fastest-growing B2B SaaS startups by revenue

B2B SaaS — defined by Sifted as proprietary software (excluding financial, healthcare and climate software) developed and sold by one business to another — was the most represented vertical on the recent Sifted 250, a ranking of the 250 fastest-growing startups in Europe by revenue.

It led with 75 of the 250 companies featured, and was followed by fintech (64) and climate tech (41). B2B SaaS did, however, have the lowest average three-year compound annual growth rate (CAGR) of all the verticals at 178.7%.

Only one B2B SaaS startup ranked in the top 10: Paris-based mobile app publisher Kovalee (#7), which achieved a CAGR of 626%. It finished top of the Sifted 50: France Leaderboard published in November.

The B2B SaaS industry has had somewhat of a resurgence in Europe in H2. It was the only vertical tracked by Sifted that saw equity funding levels increase, from €4.8bn to €4.9bn, putting it top of the tree ahead of healthtech and climate tech according to Sifted data published in its H2 report.
