Groups360, a platform for booking group travel, announced it has raised $35 million from Zigg Capital, Blackstone Innovations Investments and Fir Tree Partners. The funding, according to Groups360, will enhance the adoption of GroupSync, a proprietary booking platform for both hotel rooms and meeting space. As a result, said an announcement, the money will create greater efficiency in group bookings, accelerate the launch of housing solutions for better room-block management, and expand Groups360’s operations to bring GroupSync’s technology to hoteliers in Europe and Asia-Pacific. Dave Eisenberg, founding partner at Zigg Capital, said meeting planners increasingly expect their entire hotel purchase experience to be “seamless, instantaneous and online.”  He said Groups360 has built an integrated, intuitive platform that benefits hoteliers and event organizers anywhere in the world. As a result of the rapid adoption of GroupSync technology, according to the company, it is anticipated that an additional 20,000 hotels will begin offering instant group booking in the months ahead. Already available at nearly 7,000 properties globally, instant booking gives planners the option to skip the RFP process for smaller group reservations, taking hotel sourcing time from months to minutes.
