An online company that allows customers to create one-of-a-kind T-shirts, hoodies, jackets, bags or accessories has secured an extra EUR10m (US$12.7m) in funding.

Spreadshirt, which describes itself as "a leading company for online mass customisation," says its users range from individuals who place a minimum order of one, to the world's largest brands.

The new investment in Spreadshirt has come from private equity firm Kennet Partners, and existing investor Accel Partners, and will be used to add new products and capabilities to the online platform.

The company, which has operations in Europe and North America where it employs 300 people, also hopes to strengthen its international footprint.

"Spreadshirt mixes an online platform with the offline worlds of fashion, mass customisation, and real-time manufacturing," says CEO Jana Eggers.
