Octer, a mobile app that allows users to shop from multiple retailers such as John Lewis and Topshop on a single platform, is aiming to raise £700,000 through crowdfunding.
The amount is being raised through equity-based crowdfunding platform Seedrs in exchange for a 7.48% stake in the business.
The new round has raised 60% (£422,760) of its target so far.
It is Octer’s second round of funding. In May 2014 the company, previously known as Shareight, raised £600,000 in 24 hours.
Octer earns a commission from the retailers for each sale but does not charge customers extra.
Other names on the platform include London department store Liberty, Ben Sherman and French Connection.
