Greater Manchester-based MusicMagpie will raise £110m next week when it lists on the Alternative Investment Market.
The Stockport-based 'recommerce' site, where users resell consumer tech like smartphones and games consoles, said its share placing on London's junior stock market will see shareholders receive £95m and the company £15m.
That will give the firm, which employs more than 1,000 people in the UK and US, a valuation of around £208m on admission, a statement said on Friday.
The firm, founded in 2007, said the placing attracted "strong support" from "high quality institutional investors", and was comfortably over-subscribed.
It will launch at 193p a share on Thursday, and the firm said directors and senior management will own around 11.5%, with a free float of 53%.
Steve Oliver, CEO and co-founder, said: "We are thrilled that MusicMagpie’s circular economy model has resonated so strongly with investors, and are delighted to have received such a high level of demand for the Placing.
“Given the ongoing move to tackle the growing problem of e-waste and the fact that consumer attitudes towards buying refurbished consumer technology products are rapidly changing, we believe that there is significant potential for MusicMagpie’s future growth prospects.
"In the UK alone, we estimate that people are sitting on around £16.5bn worth of technology that they no longer use, and that only a small percentage of consumer technology items are currently recycled.
The listing on AIM of MusicMagpie reflects not only the success that we have enjoyed to date but also our confidence in our ability to capitalise on the favourable long-term trends that continue to drive the company’s strong performance.”
