Musicmetric's products allow record companies and artists to analyse the habits and opinions of fans, using text mining and web-crawling techniques to track more than 500,000 artists and eight million songs.
Iomart Hosting will manage Musicmetric's hardware assets at its data centre in central London in a two-year deal worth an undisclosed sum.
Sarah Haran, managing director of Iomart Hosting, said: "Analysing the online real-time buzz for anything, whether it's Amy Macdonald's new album or the latest video release from Lady Gaga and Beyonc, requires an absolute guarantee about up-time.
"There is little point in collecting data that is hours old, or that contains gaps; it has to be live and trending.
"(We're] delighted to be able to demonstrate to companies like Musicmetric that we (can] ensure a true, round-the-clock service."
