School dating websites
According to Spira, about 25% of users are 30 years or younger, and there's no guarantee they're college grads.
Date My School is the only dating site that specifies the user's alma mater.
Some have compared it to Facebook -- pointing out that the social network was also open to only college students when it began.
But Alexa insists Date My School is not the next Facebook.
"If somebody really has their heart on meeting somebody from Princeton, this is a great way to narrow down the search," Spira said.
"If you go to any other dating site, you have to have conversations with other people for weeks before you can be sure it's safe, that (the person) is not a freak." With Date My School, there's an initial trust that stems from choosing dates who share common interests and live on campus or attend a nearby school.
Karent Zorogastua, a second-year grad student at Columbia's School of Public Health with a hectic schedule, registered with but stopped after guys she was not interested in contacted her.
"There was one guy who looked like Flavor Flav, and I was like, 'Oh no, this is not working for me,' " she said.
"I think we are responsible for more than half of the dates and meetings between students on campus," Alexa said.
He added that the site is successful because it's safe, and it works.
