Benchmark, RRE, DFJ Gotham, AOL Ventures and Occam Partners also participated in the round, which took the company’s fundraising total to $48m.
Sailthru said it will use the funds to expand its sales and marketing teams to secure a bigger share of the omnichannel marketing technology industry, which is expected to reach $19.8bn by 2015.
The company’s revenues more than doubled this year compared with 2012 as it added new customers including Mashable, Rent the Runway, Acumen Brands and Khan Academy.
Scale partner Rob Theis said, “Sailthru is advancing revenue optimization to a new level with a proprietary algorithmic processing engine and a CRM system in a closed loop architecture.
“They provide modern marketers with a single platform solution delivered as a SaaS model.
“These types of companies, of which ScaleVP’s invested in several, consolidate best of breed systems into unique, simpler and more cost effective platforms that prioritize automation for better business performance.”
Other companies backed by Scale include enterprise-grade database maker DataStax, which raised a $45m Series D round earlier this year.
Back in May the firm closed its fourth venture capital fund on $300m, which followed a $250m vehicle raised in 2010.
