After just one and a half years in business with a beta product, social contact management start-up Hashable has sent an email letter to users announcing it is shutting down on July 25. The service will be unavailable at that time.

Hashable is a mobile (iPhone and Android), wireless app for organizing social contacts. The site billed itself “ the best way to save and remember where and when you meet people”.  It featured a social business card, a unified address book, notation facilities, and follow-up reminders to keep relationships current.

The site was founded in October 2010 by Michael Yavonditte as CEO and founder and  Emily Hickey as CMO, although she has subsequently left the company. Other officers included Teddy Jawde as as vice president of products, David Sebag as director of products, and Todd Coleman as director of engineering, Jane Kim as vice president of business development, Rick Eaton as CFO, and Oz Lubling as director of user interface.

Early investors included angel Nihal Mehta, Daniel Recanati, Dennis Phelps and Eliot Durbin. Hashable  recieved $4 million in Series A financing in November of 2010 from Union Square Ventures, Jeff Singer and Rhodium.

Based in New York City, the site had 17 employees when it launched to the public at the 2011 SXSW Conference. But it essentially stopped communicating almost as soon as it started. The company blog ceased publishing in November and has not been touched since, a fact which makes its parting lines drip with irony.

“While we are still very passionate about making better connections and meeting new people, the time for us has come to focus our energy elsewhere,” said the letter, which was sent to all active users of the site.

Hashable said users who have stored valuable information on the site will have the opportunity to save the data by logging on to Hashable.com and exporting their full history as a .csv file to their own hard drives.
