The mobile app created by St. Louis Park-based entrepreneur Blair Sargent took off thanks in part to advertising on Facebook.
But now he's suing the social media behemoth in federal court, saying the company stole the name of his app, Lasso, and is tanking his business.
"I didn't want it to come to this," he said. "I'd like them to stop using the name."
Sargent first started his company, RoundmUp, in 2014 to develop an app for event planning. That morphed into Lasso, a social media app that aims to get people to put down their phones and meet face to face at bars and restaurants. He went to college-area businesses in the Twin Cities and made deals with them: If his app could get four people in the door, for example, the customers would get a free pitcher of beer. Eight people meant a free appetizer.
Sargent would ultimately get a payment from the restaurants, while the businesses made money by attracting groups that ordered more food and drinks.
Sargent couldn't name his app RoundmUp due to infringing on the name of the popular weed killer. He settled on Lasso.
"I wanted to keep with the iconology of rounding up friends, like a lasso," he said.
He trademarked the name and poured nearly $100,000 into marketing the app, including about $12,500 to advertise on Facebook from May 2017 to September 2018, according to his lawsuit.
