In the age of traditional blogs, David Karp wanted a place where he could use a tumbleblogging format, better known today as a microblogging platform. This style of blog would offer the ability to share multimedia posts such as videos, short text posts, and pictures. After waiting for a while, he decided he was done waiting and ended up launching his own microblogging platform. That platform is what we know today as Tumblr.
At the age of 20, Karp launched Tumblr with the help of Macro Arment. The site was released in February of 2007, and within just two weeks, Tumblr had over 75,000 users. Today, Tumblr boasts over 359 million blogs. Six years after its launch, Karp allowed Yahoo! to acquire Tumblr for $1.1 billion.
Karp is admirable in his ambition to start his own tumblelog. He saw a need and since it was not being filled, he filled it himself. He created a platform that did not exist yet and paved the way for others to come along in different iterations—Pinterest, WeHeartIt, etc. His idea and drive certainly paid off literally, but seeing how he took the initiative to do it himself inspires me not to think of myself as incapable of creating something just because no one has done it before. Karp stepped out into an area no one had explored yet, and created a new market and space for innovation.
