The Wall Street Journal just covered the story of a startup Quandl.com which has 30,000 registered users, and just raised $5.4 million to expand.
The story goes on to note that one of the co-founders of the company in 2010, Tammer Kammer is quoted as saying:
“My eureka moment came when I thought how is it that in 2010 all human knowledge is consolidated on Wikipedia and quantitative knowledge is a huge mess?’” he said.
“He bought a Web domain for $10, hacked together a prototype website and put it up. Users started to find it, so he took the prototype to angel investors, who gave him enough money to write a better prototype.”
Its an interesting read.
