Sailthru, a marketing personalization startup, announced its recent $20 million funding it raised in a Series C round. The round was led by Scale Venture Partners, who will also be working with the startup as they intend to execute their plans for an international expansion. As a result of the significant investment, Scale partner Rob Theis will be joining the board of directors at the US startup. Existing investors Benchmark, RRE, DFJ Gotham, AOL Ventures, and Occam Partners also participated in the said round. Sailthru earlier raised $19 million in Series B funding less than a year ago, said TechCrunch.

According to its Crunchbase profile, Sailthru has been leading in providing technology to personalize marketing communications. Utilizing automatic analysis of large data sets via its technology Smart Data, the results are said to be omnichannel brand experiences.

Sailthru Chief Executive Officer Neil Capel said that with money still left at the bank and the additional funding, the startup will not be worrying about funding for its operations next year as it grows its business overseas. Capel also explained that its product's edge against other email marketing company products is that its customization is to a point that it personalizes every single touch point regardless of the communication medium. Capel also said that at the end of the day, big data companies are not focusing on offering true personalization to its users and instead opt to divide its users into several demographic segments.

"We're essentially real-time, we're able to personalize every single event. As opposed to everyone else who says they're real-time, and the consumer sits in this bucket," Capel said.

Capel counts Mashable, Rent the Runway, Acumen Brands, and Khan Academy as among its clients. Capel also said that Sailthru's revenue that was generated for the year 2013 was double than the revenue earned last year.
