Advent Venture Partners has announced that it has invested $5m (£2.5m) in online customer feedback provider Fizzback Group.

Formerly known as ‘Instant Market Intelligence’, Fizzback works with a number of companies, National Express included, to help them capture and analyse feedback from their customers.

After initial backing from The Accelerator Group and other angel investors, the latest round of investment will be used both for marketing and product development, as well as allowing the company to employ more staff.

Frédéric Court of Advent Ventures is impressed by Fizzback’s growth:

“We believe that Fizzback is creating a new market opportunity with its very innovative and unique customer feedback solution.”

“Fizzback has shown impressive growth since inception and we believe that its team is well positioned to capitalise on this exciting opportunity.”

Advent Ventures was established in 1981, and invests mainly in the technology and life sciences sectors.
