I am a cofounder of PIE, a startup accelerator that is part of the Google for Entrepreneurs program. If you have any questions about the program, please let me know. (And thanks to zacharycohn of Startup Weekend for the nudge.)
We were lucky to partner with Google last year, as well -- before this program was formalized. They were very open to exploring options with our (then) relatively new program. I'd recommend contacting them directly.
I work for Startup Weekend, one of the projects/resources listed here. If anyone has any questions, go ahead and let me know and I'll do my best to answer!
Remember that our focus isn't to make 15 new startups in a city over a weekend, our focus is really education. We believe in "experiential education," or that the best way to learn something is by doing it.
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.
My cofounder and I knew we wanted to work together after attending a startup weekend and started Customer.io . During startup weekend we built a wifi / power outlet finding mobile web app.
Seeing this made me really realize that Google is huge. Huger than I could imagine.
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.
Hi! I'm also a Startup Weekend employee. You might check out http://startupweekend.mx/ and say hi to our colleagues Gustavo and Melina. They may also have some insights into the Mexican entrepreneurial ecosystem.
