A TECH firm which manages online marketplace listings for retailers is seeking to raise finance to fund its expansion in the US.

Seller Dynamics, which previously raised £1.2 million from sources including the Scottish Investment Bank and angel investors, is also planning improvements to its software to attract new customers in the UK.

The Stirling-based firm has been developing its technology – which is provided to retailers via a SAAS (software as a service) model – since 2011.

Its proprietary software allows retailers to list their stock on sites including eBay and Amazon.
