Riccardo G.’s profile on Couch Surfing.com, the website that partners intrepid wanderers with willing hosts, notes that he lives in the “best neighborhood to go out and have drinks,” that he offers a “cozy/clean/nice sofa/couch” and that he’ll even let you bring your “small dog, if you just can’t live without him.” He describes himself as “amazing, outgoing, funny, smart” and says his interests include friends, eating, drinking, the gym and puppies.His photos show the good-humored Latin American native — dark, handsome, and fit — in exotic destinations around the world, from Cairo to Capri.

Hookup web fun-70

(Riccardo and other Couchsurfing users quoted in this article asked to be identified by pseudonyms.) On the business front, the crowdsourced hospitality site has been experiencing a rough patch lately.

After a controversial transition to a for-profit model in 2011, which brought $22 million in funding in the past two years, growing pains have set in.

In October, layoffs claimed an estimated 40 percent of the staff, and CEO Tony Espinoza announced his departure — giving an opening to competitors like Be Welcome and Hospitality Club.

In an email interview, the site’s interim CEO Jen Billock told Business Insider that “members are ...
