The Swedish company has grown by a massive 30,114 percent over the last four years, according to Deloitte.
The list was topped by Catawiki, a growing online auction house based in the Netherlands, which saw its turnover increasing by 45,000 percent.
“Achieving a position in the EMEA Fast 500 is always an impressive feat but the rates of growth for this year are particularly inspiring," said David Cobb, partner-in-charge of the Deloitte Technology Fast 500TM EMEA programme in a press statement.
"These results highlight the strength and determination of the Technology sector across this region with a clear indication of some of our business leaders of the future."
Swedish Software companies Kaustik AB and Inteleon AB also reached the top 50 on the list, with a total of 37 of the full list of 500 companies in the ranking coming from the Nordic nation. This made Sweden the fifth best represented country.
However, France dominated the rankings with the most entries, for the sixth year in a row, while Israel celebrated having two entries in the top five. Four entries in the top 10 came from the UK.
