Tungle launched today. You can now download the beta version of the Tungle Outlook plug-in that lets you share calendars and availability across organizations.

The company is headed by Marc Gingras and Fang Yang, who have a long history as a team in Waterloo. I first met Marc eight years ago when he was heading the Kitchener-based development office of Entrade. Marc, Tungle's CEO, is now in Montreal, while Fang, the CTO, is based in Waterloo. Tungle raised $1.5 million last year from JLA Ventures and Desjardins Venture Capital, with additional funding from a U.S. based angel investor.

Marc blogged about the launch earlier today.
