TechStars New York has had three classes for a total of 37 startups since it launched in the beginning of 2011. The guys at social media sentiment analysis startup Buellr have arranged a ranking of the top ten of graduates from all but the current class.

"What we're doing now is culling together sentiment analysis from a variety of data providers," cofounder Adrian Grant explained. "We then combine them in hopes of normalizing the dataset. Then we rank them by positive mentions, number of mentions, who is saying the comment and various other components that have their own respective weights assigned to them."

Unsurprisingly, the popular Foursquare app Timehop came in first, even though cofounders Jonathan Wegener and Benny Wong were working on another idea entirely, FriendsList, during the first session of TechStars back in January of last year.

Speaking of working on another idea entirely, that's how Buellr came about. "We viewed this product, social media reviews, as a 'day off' kind of project, in the vein of the movie 'Ferris Bueller's Day Off,'" Mr. Grant said in an email.

The rest of the rankings are:

10. Onswipe, which makes publishers' content look good on mobile browsers
9. Wantworthy, a bookmark list for fashion.
8. SideTour, the marketplace where amateur tour guides, chefs and art buffs can curate activities for travelers and idle locals.
7. Nestio, the apartment hunt organization system.
6. Shelby.TV, which creates a video playlist by pulling links out of your social media streams.
5. CrowdTwist, a consumer loyalty analytics tool.
4. Coursekit Lore, the socially-enhanced classroom management platform.
3. Contently, the marketplace for mercenary bloggers and content-hungry publishers to find each other.
2. Ordr.in, which turns any website, app or device into a menu and a way to order food.
1. Timehop, an email reminder of where you were a year ago today.

CORRECTION, April 25: An earlier version of this post said the rankings include all three classes of TechStars NY; that is incorrect. The original rankings also included TechStars graduate Red Rover--but used data for an unrelated company by the same name. "We are building Buellr lean and thus far have gotten some solid feedback. That being said, our internal processes clearly still need to be refined," Mr. Grant wrote in an email. Betabeat regrets the errors.

Adrian Grant and Vivek George, self-identified "NYU biz guys," may not have gotten into Y Combinator. But they did teach themselves to code. While working on their first project, they struggled with finding the best software-as-a-service tool for the job--which led them to abandon the idea and start working on a simple, crowdsourced product reviews site. "We went looking for reviews and all the results were uber spammy. That's when we got the idea for a transparent product review site," Mr. Grant wrote in an email.

Mr. Grant reached out to Betabeat in response to an unscientific post entitled, "10 Startups, Ranked in Order of Hotness." Buellr does similar rankings complete with excerpted tweets, just, you know, based on "data."

The alpha version of Buellr launched on Friday the 13th, and so far Mr. Grant and his cofounder Vivek George have analyzed sentiment for vodka, smartphones, summer movies and Y Combinator's 2012 winter class (go 99Dresses!) based on what people are tweeting about them.

Buellr analyzes Twitter, Facebook, YouTube and more than social media sites for mentions of products, the site says. The algorithm then creates a simple top 10 list. It's a "Klout for products," Mr. Grant said.

Scaling is the next step for the nascent startup, which doesn't have the ability to analyze larger datasets yet. The founders are working on overdrive to add this feature to Buellr within the next two to three weeks, Mr. Grant said.
