The Hut Group made headlines in March, when it bought high-street music retailer Zavvi and relaunched it as an online business.
Zavvi collapsed after the closure of Woolworth's entertainment distributor Entertainment UK left it without stock.
Matt Moulding, chief executive of The Hut Group said the funding will be used to expand its acquisition programme and drive organic growth.
"This funding helps provide the necessary platform to continue our buy and build strategy following on from the successful acquisition of the Zavvi brand earlier in the year. We remain focused on launching new product categories to broaden our proposition for both existing and new partnerships," he said.
The private investor has not been named.
The Hut Group also provides e-commerce services for Asda, WH Smith and Shop Direct, and has recently singed deals with Borders and Littlewoods.
