Want to know which venture capitalist invested in which web 2.0-company? Take a look at Crunchbase. It’s all there. And the best thing is: it has a beautiful and responsive API. I couldn’t resist downloading a few entries from this database to visualize the network of investors and companies that’s evolving around the new microblogging and lifestreaming tools.
So, here’s a network map of the most important companies offering microblogging or lifestreaming services and their investors. The companies are symbolized as green circles and the funding organizations as red squares (click to enlarge). It’s interesting how Ron Conway connects Seesmic, Twitter and Pownce with his investments. The rest is not exactly heavily linked by funding streams. Next will be a visualization that also shows the amount of money raised and the size of the companies.
