Founded in 2009, the Massachusetts-based startup now has $4.5 million in total funding.
Groupize plans to use the new funding to expand its salesforce, support its customer base, and accelerate the launch of a new booking feature for small groups.
“The Groupize approach is perfectly complementary with cloud-based solutions that other companies in our portfolio are offering hotels to drive business in the online world,” says Jeffrey Jackson, managing director of Thayer Ventures. “We are excited about the future.
Groupize says more than 8,000 properties and several websites are using its group-booking solution. Among the hotel participants are Affinia Hotels, and Manhattan’s Park Central Hotel and Row NYC.
