Classtivity has bagged $2 million in seed funding from various angel investors. At the same time, the startup is rebranded to ClassPass to make its fitness program more effective, according to TechCrunch.

Fritz Lanman, SV Angel, Blake Krikorian, Gordy Crawford, Hank Vigil, and Owen Van Natta are among the several investors in the seed funding, the report added.

ClassPass initially ran a pay-per-class program that allowed users to locate gyms with available slots for their desired workout. Later on, the company switched to a monthly $99 program that allows users to attend any class at any gym to make them adhere more to the workout routine. The service works by integrating user data with the gym's system to skip the registration process upon entry, the report detailed.

PatriciaFit founder Patricia Whitcas said of the program: "I began teaching my TTL class just a year ago with a small, loyal following. Since becoming a class provider through ClassPass, my classes have been consistently full and/or sold-out with many repeat students, all without any other marketing."

To date, ClassPass has integrated more than 65 boutique gyms in New York. It has also tapped 20 gyms in Boston. As of now, the propgram is still in beta, TechCrunch reported.
