The Series B round more than doubles Sailthru’s previous financing, which comprised a $1m seed round in 2010 and an $8m Series A in 2011.
DFJ Gotham and corproate venture capital firm AOL Ventures also took part in the latest round, which will see Benchmark’s Bill Gurley join the Sailthru board of directors.
Sailthru said it increased revenue by 270 per cent in the past year, with an average monthly growth rate of over nine per cent.
The company now supports clients across five continents, recently opened a West Coast office in San Francisco and plans to expand into Europe in the second quarter of this year.
Gurley a general partner at Benchmark, said, “As all digital businesses evolve to the next level, the best companies are focused on how they can deliver an individualized experience for each and every customer.
“Sailthru is a company that exemplifies this by placing the individual at its core to enable companies to adopt a personalised approach to serve their customers.
“Companies that embrace this approach see much higher conversion rates, and as a result higher revenues and more satisfied customers. It’s a powerful combination.”
Earlier this month IT group DataXu raised $27m of growth capital led by Thomvest Ventures to fund its ongoing global expansion and further development of its digital marketing software.
That fundraising was also supported by the company’s existing major investors Atlas Venture, Flybridge Capital Partners and Menlo Ventures.
