Whoworks.at Shows You Who In Your LinkedIn Network Works At The Sites You Visit

Finally there’s a reason for young people to use LinkedIn! If you’re having trouble keeping track of where your friends work in this current startupgasm, WhoWorks.At was made for you.

Just download the Chrome extension and it will let you know who in your LinkedIn network works at whatever site you’re currently browsing in Chrome, whether it be Facebook, Google, TechCrunch or some stealth startup. It is amazing.

When you click on the Whoworks.at button at the right of your Chrome toolbar, your first 1st degree LinkedIn connections will show up first, followed by your 2nd and 3rd level connections. You can also toggle the extension to view people who have been recently hired or promoted at the company you’re visiting. I’m not kidding, this is a godsend if you’re a recruiter or a journalist/investor.

Creator John Britton, who is also a developer evangelist at Twilio, plans on integrating Whoworks.at with other services including Facebook and Rapportive, which was the inspiration behind the service. Interestingly enough, Whoworks.at doesn’t use a public LinkedIn search API (non-existant despite high demand), but instead finds its connections through the searchbox on LinkedIn that auto completes company names.

Says Britton on his future plans, “I’ve been in contact with the founders of Rapportive and they’ve put me on their beta list. As soon as they have public APIs available I plan to enhance the functionality of WhoWorks.At to be less dependent on LinkedIn. Additionally I would like to add the ability to star people, view recent gmail conversations, and take notes on contacts. Facebook integration will come further down the line, depending on user feedback.”

Ooh, Facebook integration …

For those of you who can’t wait, invites for the first 250 TechCrunch readers are available here. And if you don’t make it in time you can sign up like a mere mortal for the beta here. Don’t worry, they’re pretty fast to respond.
