It’s getting increasingly easy for Europe’s startups to scale up — there’s more money going into later stage rounds, and more companies are securing the investment needed to grow. 

In 2014, $1.7bn was invested into European companies at Series B level. In 2019, it was $5.5bn — three times that — and, despite global pandemonium, 2020’s figure looks set to equal last year’s too.

Much of that capital gets funnelled straight into hiring — securing access to talent is cited as a top business priority by leaders of 100-person-plus companies. But behind the scenes, many of these high-growth businesses will also be investing in their back-end systems to help streamline their increasingly complicated core processes and ensure full visibility of them internally and for investors. 


Using data from European Startups, Sifted analysed the biggest scaleups at Series B in Europe this year, based on headcount growth across the last six months. 

Only startups with more than 50 employees and with a €150m valuation or more are included. 

Here’s which startups have grown the most:

The biggest scaleup of 2020 is London-based Hopin. Launched last year, its team has expanded by 294% in the past six months, to 193 employees. The online events platform has 3.5m users and has worked with organisations like the United Nations and NATO.

Earlier in November, Hopin secured a $125m Series B round, led by US investment firm IVP, and the company is currently valued at $2.1bn. 

“We wanted to be the fastest-growing company in the world — and we don’t want to ever stop doing that, at any stage,” Hopin’s founder, Johnny Boufarhat, told Sifted when its latest funding round was announced.

The next biggest scaleup is Primary Bid which has seen its staff numbers grow by 80% across the last six months. 

Like Hopin, Primary Bid is also based in London. Its platform aims to help individuals to invest in public companies on equal terms with institutional investors. 

Its £38.5m raise in October was the biggest European fintech round of the month. The funding came from, amongst others, London Stock Exchange Group, Draper Esprit and OMERS.

Swappie is currently valued at €145-218m. 


Vienna-based PlanRadar, founded in 2013, has scaled its staff numbers by 49% in the last six months, to 118. 

PlanRadar is a cloud-based SaaS (software-as-a-service) platform for construction — aiming to help companies with the documentation, task and defect management of their real estate projects.

Finnish computing startup IQM announced a breakthrough in October that should make quantum computers more accurate and easier to scale up.

The company will soon have one of Europe’s largest teams of quantum engineers: it’s scaled its staff by 48% over the last six months, to 59 employees. 

The startup secured €39m in November 2020, led by German VC MIG Fonds, bringing its total funding to date to €71m.

“Every successful company has once looked small against established players. I am glad that we are already being mentioned along with IBM or Google,” Jan Goetz, IQM’s chief executive, told Sifted on the announcement of its latest funding round.


Paris-based Livestorm, launched in 2016, makes software for companies to host webinars. 

The company saw a spike in interest after the coronavirus pandemic hit and has grown its staff by 46% across the last six months, to 54. Livestorm’s secured €31.9m in funding so far, and is worth between €109 and €164m.
