The list, updated yearly, contains some of the UK’s most successful technology companies across a variety of industries – from internet retail and software development to social media and advertising.
“We are delighted to have been confirmed once again as one of the UK’s fastest growing technology companies and especially so after seeing the high standard of the other companies on the list,” Mike Thornhill, CEO of the online sports retailer, which was ranked 100th, says.
“It has been a very successful year for us and this in many ways is a crowning achievement.”
Entry to the list is only possible by demonstrating consistent high growth over a four-year period.
Activinstinct’s average growth of 42 per cent per year over the last four years was enough to see the company make the grade for the second time in three years, having previously gained the award for the first time in 2010.
As well as its successful retail operation, Activinstinct also runs websites for the likes of Gatorade and MBT.
In 2012 sales were £15.5 million, according to The Sunday Times.
