SessionM, a Boston-based company that’s developed a dynamic CRM using customer behavior to further engagement, announced it has secured $35 million in Series D funding. The round was led by General Atlantic, with participation from Salesforce Ventures as well as existing investors Causeway Media Partners, Charles River Ventures, Highland Capital Partners and Kleiner Perkins Caufield & Byers.

“The overwhelming majority is going to people,” Patrick Reynolds, vice president of marketing at SessionM, told us of the funding.

“The overwhelming majority is going to people.”

To date, Reynolds said SessionM has approximately 175 total employees, with about 100 in Boston. “We will very easily see that number doubling in the next 18 months,” he shared.

The company is looking to hire people across every discipline – from engineers to sales professionals. “The biggest limiting factor, as with most companies, is people… We hope to rally the Innovation District around this funding news,” Reynolds said.

He added that capital will also go towards product development and help the company continue its international expansion. “We currently have an office in the U.K. but would like to reach EMEA, Asia and all that comes afterwards,” Reynolds explained.
