Yahoo’s $US1.1 billion acquisition of Tumblr really put New York tech on the map this year.
But over the past few years, New York City has become a tech hotspot.
New York has become home to some of the tech industry’s most promising companies, including Etsy, Rap Genius, Makerbot, Kickstarter, Tumblr, and Infor.
All in all, it’s been a great year for New York Tech. So we created the Silicon Alley 100 to celebrate people who did the coolest things in 2013.
So what constitutes someone who’s done something cool?
We prioritised entrepreneurs over investors, since it’s a lot harder to start a company than to fund one. We particularly prioritised startups with amazing exits and people who had big, game-changing roles at the tech companies.
Next, we valued companies that really exploded over the last year (the Upworthys and the Vines), followed by entrepreneurs who launched cool new companies. Then we dove deeper into the ecosystem and recognised the money behind the startups — the angel and early-stage investors.
Thanks to all of the people who make New York an amazing place to launch a startup.
Many companies on the list share investors with Business Insider.

Founder and CEO, Tumblr
David Karp became fantastically rich this year when Tumblr sold to Yahoo for $US1.1 billion. Karp resides in a 'mildly Steampunk' apartment in Williamsburg, a young, hip neighbourhood in Brooklyn, New York. He loves New York and simply doesn't understand why anyone would want to live in Silicon Valley, even though many of his business peers are based there.
This year, Shutterstock founder and CEO Jon Oringer became NYC's first tech startup billionaire. He also created one of the internet's first pop-up blockers and is a certified commercial helicopter pilot.
Shutterstock, a stock photo and video site, went public last October.
The 39-year-old owns about 55% of Shutterstock. His 18.5 million shares were valued at $US1 billion in June.
