It’s a mix between Kijiji and Craigslist, with a dash of eBay.

The 20-something leaders of Uniiverse.com have taken old social-media concepts and mashed them together for a new platform dubbed “collaborative living.”

“It’s an online marketplace for activities and services that happen offline,” said Ben Raffii, president and a Uniiverse chief executive officer.

In other words, the site ‘ whose founders include Western grad Craig Follett ‘ isn’t just another way to keep friends updated about your “status” or a tool for instantaneously sharing strokes of genius. Instead, Uniiverse aims to let people connect via the Internet then meet face-to-face for everything from ultimate Frisbee showdowns to math tutoring.

One of the things that sets Uniiverse apart from other ad-listing sites is the “Trust Score” assigned to each user. Kind of like eBay’s feedback function, the trust quotient lets “posters” build a repertoire and helps browsers decide who should be avoided.

With a team of Western students helping, Uniiverse ‘ headquartered in Toronto ‘ launched Feb. 7. By Sunday, about 30 posts had been made for services and events in the London area.

The way people choose to use Uniiverse is as unlimited as their imagination. Entrepreneurs may choose to offer cooking classes or language lessons, some may be looking for people with whom to share rides and others might be searching for some new yoga mates.

The site is building what Follett ‘ the Western grad ‘ calls a “sharing economy.”

“(One) … where access and experiences are more important than ownership,” Follett said in a statement. “This movement … will build stronger communities.”
