Ben Rattray was set on being an investment banker until his senior year of undergrad at Stanford University when one of his younger brothers came out as gay.

"He told me what hurt him most wasn't people who were explicitly anti-gay, but the people who refuse to stand up and speak out against them," Rattray said of his brother in an interview with AOL.

So the 31-year-old created a space where people could make a difference -- a change. He founded, an online petition site for people to come together for a cause, citing a generational need for giving power to people's voices that also harnesses social media.

Now named one of TIME's 100 Most Influential People of 2012, Rattray is still discovering just how great that need was.

"We had no idea how much power individuals could have, and what's unique now is not petitions specifically, but the combination of petitions and social media," Rattray said. "And the combination is much more viral, much more explosive than we possibly could have imagined."

Now that explosiveness is going international. Rattray said more petitions are being posted everyday from around the world -- a change he hopes continues.

"That desire for people to come together and make a difference isn't uniquely American," Rattray said. "It's a fundamental human desire to mobilize around the things people are passionate about -- and millions of people are joining every month, and it's happening every, every day."
