Integral Ad Science has cause to celebrate, and not just because its fresh off a $30 million Series D round of funding. The company is expected to Tuesday announce it doubled its revenue and retained 98% of its clients in 2013.

Scott Knoll, the company’s CEO, told RTM Daily that he doesn’t know what the typical percentage is for software-as-a-service (SaaS) companies when it comes to client retention, but the 98% figure is something he is proud of.

“When you are a SaaS, which is a model we are similar to, you are really counting on repeat business,” he said. “One of the big areas we invested resources in was our client service team, and making sure we had enough focus in that area. I think that’s one of our strengths.”

In addition to doubling its revenue, the company also doubled its headcount, Knoll shared. He added that he expects the employee base to grow “probably by another 60-to-70%” in 2014.

Knoll also noted the success the company had overseas in 2013. It launches its first international office in the UK in February 2013, with just one employee. There are now 14 Integral employees working there.

“We want to make bigger investments in the international markets,” Knoll remarked. “So we’re going to be opening up several new international offices -- a couple in Europe as well as Asia-Pacific.” Knoll named Germany and Singapore as possible locations, but he was careful to add that nothing is set in stone. Japan and Australia were mentioned in the press release as other possibilities.
