For the fifth year in a row Adyen and TNW teamed up to find the fastest growing companies in Europe’s six hottest startup ecosystems: the United Kingdom, The Netherlands, Germany, France, Spain, and Sweden. The winner, mattress business Emma (Germany), was announced tonight at TNW Conference Founders Dinner in Amsterdam, The Netherlands.

To search for the fastest-growing startup, TNW reached out to hundreds of companies identified as fast-growing based on their research and asked them to sign up for the Tech5 competition from January to March. Since TNW needed to verify that the growth rates were legit, all the companies who signed up were asked to confirm their growth rates by signing an affidavit.
