SOCi Inc., a local social media content marketing company, raised $2.25 million to expand its sales verticals and innovate its platform. This funding is in addition to the $1.5 million the company raised in its Series A round.

According to the company’s release, new investors include Facebook’s Doug Hecht and venture capital fund GrowthX. Repeat investors include Trevor and David Klein, co-founders of AutoAnything (acquired by AutoZone), and Asaf Benheim, founder of iMatrix (acquired by Internet Brands).

SOCi will use the additional funds to bring a more scientific and scalable approach to social media management for enterprises, multi-location brands, franchises and digital agencies.

SOCi, founded in 2012, uses social marketing on Facebook, Twitter, LinkedIn and Google+. It launched in early 2015 and has since grown from five partners to 85 partners. The company added 20 new employees this year and continues to hire in 2016.

Some of its well-known customers include Yellow Pages, Rhino Linings and Little Caesars, as well as 40 percent of the National Multifamily Housing Council’s 50 largest apartment managers.
