On this day, July 6 in the year 1986, the founder of the micro-blogging site Tumblr was born in New York City. His name is David Karp, a high school dropout who became a multimillionaire at age 26.

David’s mother was a science teacher while his father was a television and film producer. They separated when David was 17. David has a younger brother named Kevin. At 11, David already learned the basics of HTML. At 15, he quit school but continued his studies at home.

David became an intern at Frederator Studios founded by animation producer Fred Siebart. Later, he found work at UrbanBaby, an online parenting firm. In 2006, he left the company when it was sold to CNET. With the money he earned from the sale, he started his own startup, a software consultancy firm which he named Davidville. In 2007, he launched Tumblr with the help of software engineer Marco Arment. Tumblr is a micro-blogging and social networking website where users can post their thoughts, feelings, stories, photos and videos.

Tumblr was sold to Yahoo! in 2013 but David remained as CEO. From the sale, he became an instant multi-millionaire with his net worth estimated at $200 million. At present, Tumblr has more than 300 million users and more than a billion page views a week. In June, 2017, Tumblr became a unit of Verizon, the company that bought Yahoo!.

After his split with his girlfriend in 2014, David remained single.
