When David Karp was 14, he was clearly a bright teenager. Quiet,
somewhat reclusive, bored with his classes at the Bronx High School of
Science. He spent most of his free time in his bedroom, glued to his
But instead of trying to pry him away from his machine or
coaxing him outside to get some fresh air, his mother, Barbara Ackerman,
had another solution: She suggested that he drop out of high school to
be home schooled.
"I saw him at school all day and absorbed all
night into his computer," said Ackerman, reached by phone Monday
afternoon. "It became very clear that David needed the space to live his
passion. Which was computers. All things computers."
26 years old, Karp never finished high school or enrolled in college.
Instead, he played a significant role in several technology startups
before founding Tumblr, the popular blogging service that agreed to be
sold to Yahoo for $1.1 billion this week. With an expected $250 million
from the deal, Karp joins a tiny circle of 20-something entrepreneurs,
hoodie-wearing characters such as Facebook's Mark Zuckerberg and
Foursquare's Dennis Crowley, who have struck it rich before turning 30.
I first met David he was 20 years old and wearing sneakers and jeans,"
said Bijan Sabet, a general partner at Spark Capital, who was one of the
first people to invest in Tumblr. "But I knew he was one of these rare
entrepreneurs that grew up on the Web and who could come up with an
idea, build it himself and then ship it that night."
founding Tumblr six years ago, Karp has been admired for his programming
skills and website design acumen but at times has been a polarizing
figure in New York tech circles because he so often blogged about his
personal life and party hopping. He has popped up in the New York Post's
Page Six Magazine and has been a recurring target for the gossip
website Gawker, where he was labeled a "fameball," a derogatory term for
someone who has an unquenchable desire for fame.
willowy, with a mop of brown hair and piercing blue eyes, Karp typically
dresses in jeans, a T-shirt and sneakers. He speaks at a rapid clip
and, often, for minutes without stopping. Technically, he never
graduated from high school, which he cracked in an interview is
"hopefully not a condition of Yahoo employment."
out and working for a time in small New York tech outfits, Karp made his
way to Tokyo, where he worked for several months for a startup. He
returned to the United States and became the chief technology officer
for UrbanBaby, an Internet message board for parents. CNET Networks
bought UrbanBaby in 2006, and Karp took the several hundred thousand
dollars he made from the sale to start his own company, called
Davidville. One of Davidville's projects was a simple blogging service
Karp's run at Tumblr has not been without problems.
He had trouble hiring in Tumblr's early days, unsure how to even
interview recruits. He often thought large companies were too big for
their own good, proclaiming he could manage Tumblr with a team of four.
But Karp stepped out of the party scene and started dating his current girlfriend, a graduate nursing
school student at New York University, four years ago. He also appeared
to get more serious about his company as it grew from fewer than a dozen
employees to more than 175 today.
"David has grown up in Tumblr," said Mark Coatney, who oversees Tumblr's relationship with media companies.
Karp's unsure footing led to discussions about his taking a different
role at Tumblr, according to two people who worked with the company and
who agreed to speak on the condition of anonymity. Because revenue was
not growing as fast as they would have liked, investors considered
putting Karp in charge of Tumblr's product development and finding a
more seasoned chief executive.
Karp denied in an interview that
there was a plan for him to give up the chief executive's job. He said
that when Tumblr's chief operating officer left in the middle of last
year, filling that job and other critical roles like head of marketing
was "top of mind," but he said there was no plan for him to step aside.
many who run so-called social Internet companies, Karp can teeter on
reclusive. In an interview last year at the F.ounders conference in New
York, he said he preferred to come to the office early to work alone,
avoiding other people.
"Where I feel the most productive and
engaged is when I'm buried in code, buried in some project, tweaking
some designs," he said. "I'm certainly introverted."
a television producer who was MTV's first creative director, met Karp
in 2000 while Karp was still in high school. Seibert's children attended
a private school on the Upper West side of Manhattan called The Calhoun
School, where Karp's mother was a science teacher.
"My wife and
Barbara became very friendly," Seibert said. "Over coffee, she was
describing how bored David was in high school and my wife said, 'Fred
really likes teenagers, you should send him over.' And that's how I met
him. He was 14."
Karp arrived at Seibert's offices on Park Avenue and said he wanted to "learn about engineering and become a good engineer."
At first, Karp came to the office a few days a week. But then, one day, Karp announced that he would be coming in every day.
"I asked him if his school schedule changed," recalled Seibert. "And David said 'No, I've dropped out!"'
said it wasn't long before Karp became invaluable. He asked him to
build the site for his new company, a Web video production outfit called
Next New Networks.
"He comes in two weeks later and he hasn't
done it," Seibert recalled. "I thought he was being a flaky 19-year-old.
But he said, 'No no, your idea is just so 2000."'
Karp pulled out
a Sony PlayStation Portable gaming device and told him that soon, Apple
would be releasing an iPod with video capabilities.
"He said, 'This is the way people are going to watch video and you really ought to be there."'
Next New Networks was one of the first video products on iTunes and was eventually acquired by Google for around $50 million.
"Because of his prescience and timing, we were ahead of the curve," Seibert said.
Seibert eventually became an investor in Tumblr and sits on the company's board.
who lives in a $1.6 million one-bedroom loft in Brooklyn with his
girlfriend and dog, said he is staying put in New York and with Yahoo.
He intends to "figure out something" with philanthropy. And one day he
might even go to college.
"At least I should be able to afford it," he said.
