Tumblr

Founded by David Karp in New York City in 2007, Tumblr is a microblogging platform that allows users to effortlessly share anything. Tumblr now hosts over 45 million blogs with over 19 billion posts to date. Our pageview to engineer ratio is 1 billion PV per month to 1 engineer. This means every line of code every developer writes has a huge impact. We are focused on building tools and technologies that will advance the state of the art in dealing with massively scaled websites as we quickly grow past 30,000 requests and 1,300 posts per second. We are also excited to deliver a range of new products that will enable users to share their own creative content, discover content, and connect to one another in new ways.
