Just before midnight on Thanksgiving, Lizelle van Vuuren hit the green button on her computer screen and Wüf, a smart dog-collar under development for nearly two years, launched its Kickstarter campaign.
Within minutes, Wüf got its first backer. Sure, it was a good friend of van Vuuren's. But that's how many crowdfunding projects should start — with support from friends and family. Twelve hours later, the campaign was at 10 percent of its $50,000 goal.
