How can I approach to sponsors if I found a accelerator in my hometown?
That being said, many real companies have come out of Startup Weekend (and many many more have come out of people meeting or working together at Startup Weekend).
But, a quick list off the top of my head: Zaarly, Foodspotting, Rover, Tioki (formerly DemoLesson), Tapin.tv (YC S12), LaunchRock, Scanadu.
+ ClassDojo - from Startup Weekend UK
+ Demo Lesson (now Tioki) - from Startup Weekend EDU SF
+ Edcanvas - from Startup Weekend EDU Seattle
I remember vividly when I first saw Google.com. I think it was at the end of the millennia. They got bigger in small increments, but now they are enormous.
I am doing my PhD research on the startup ecosystem in Mexico and it would be interested in talking with them about some of my findings.
I have been following closely the development of Startup Weekend in Mexico, and wrote research paper on that. Gustavo and Melina are great :)
