Salsify Inc., whose technology enables manufacturers to distribute product information to online retailers, has raised $16.6 million in its second funding round. In its first round, the Boston-based company raised $8 million in 2013.

Salsify offers a web-based service that suppliers of 4 million products use to distribute updated images, specifications, attributes and other product information to retailers. The company lists among its clients Newell Rubbermaid, 9 West Holdings and Bosch. 9 West is No. 215 in the Internet Retailer 2015 Top 500.

Venrock, a venture capital firm backed by the Rockefeller family, led the founding round. Also participating were investment firms Matrix Partners and North Bridge and Michael Skok, a venture capitalist previously associated with North Bridge.

“Salsify is changing the way retailers and suppliers share key information, dramatically improving data quality and transforming the consumer’s online shopping experience. They are going to have a meaningful impact on the marketplace,” says Mike Tyrrell, a partner at Venrock.

Salsify was founded in 2012 by executives with e-commerce experience at IBM Corp. and Endeca, a provider of site-search technology that Oracle Corp. purchased in 2011.
