Today, a startup called ChannelEngine, which helps retailers connect with and sell through more than 200 marketplaces, is announcing a growth round of funding to continue building out its business amid strong demand. The startup — based out of Leiden, Netherlands — has raised $50 million, funding that it will be using both to continue expanding the number of marketplaces it works with, the number of retailers that it connects to them, and to work on building out what the next generation of e-commerce will look like for all of them. Valuation is not being disclosed but as a marker of how the company has been growing at a profit up to now, it was founded in 2013 raised only around $7 million before this round, most recently doubling revenues in the last year on a base of over 450 retailer customers, with the list including the likes of Bugaboo, Staples, JBL, Polaroid, Hunkemöller, Brabantia, Reckitt Benckiser, Bosch, JDE, Electrolux, Philips Domestic Appliances, Signify, Diadora, Glanbia, Oneill, and Safavieh. The company currently manages distribution for some 6 million products from 8,100 brands across more than 200 sales channels.
