Softcat has been ranked 23rd in The Sunday Times' 11th annual Grant Thornton Top Track ranking of the UK's mid-market growth private companies with the biggest sales - a jump of 29 places from its ranking in 2014.
The league table ranks companies according to their growth, with businesses needing to achieve either sales or profit growth of at least 10% to enter.
Colin Brown, Softcat's MD, has previously tied the company's growth to its employee engagement, and maintains that this is still the case.
He said: "We're delighted to have climbed Top Track's ranks this year, and it's an honour to stand alongside many well known names.
"It's mostly down to the hard work of our incredibly motivated staff, whose efforts resulted in strong growth in 2014, so a huge thank you to them.
"We invest a lot of time and money in our staff, hiring the best people, designing the best training for them and rewarding them financially and with opportunities to progress their careers.
"We have maintained 98-99% employee satisfaction ratings even as we have doubled in size, which in turn helps us deliver the highest levels of customer satisfaction."
