INC - Mar 29 - Joel Simkhai founded the company behind an incredibly popular app called Grindr. Blendr began as an idea as early as 2010, just right around when Grindr really started to gain popularity. Blendr officially launched in September 2011, about two years after Grindr went live. Both companies are self-financed and through premium services and advertising revenue, though Simkhai is reluctant to offer revenue numbers. He says the company has spent no money on marketing, and downloads are completely driven by word of mouth. He does not plan on taking outside funding.
