This reminds me of an analysis I once did: https://github.com/astanway/Crunchbase-Network-Analysis

The data from Crunchbase is very, very dirty, but I managed to clean it up a lot. Feel free to fork if you want pre-built NetworkX graphs.

This is really interesting. I'm surprised you found that startups with higher centrality raised less money. Not sure how to explain that. Your investor graph has edges pointing both from investors to startups and back, right? Anyway, thanks.

Mm, no, just from investors to startups. Startups don't invest in investors :)

I actually did a lot of Crunchbase clean-up for http://seedtable.com - if people are interested in this perhaps we should collaborate on some kind of data cleansing project.
