Introduction

AngelList is probably the largest open network of start ups, founders, and investors. It also provides a nice API for others like myself to play with the data. I had some fun analyzing the dataset since January and wanted to put a bit more formality into sharing the result. So I will be organizing the methodologies and results as a series of posts instead of tweets.

Understanding investors has multiple benefits.

  1. One can see the trend in markets. It is important not only for identifying pain points but also pivoting on your existing business or ideas.
  2. Use it to target more relevant investors. Perhaps even a lead investor.
  3. And more…

Methodology

Investors

Investors are filtered from a full list of users who had a “startup role” of “past_investor”.

Primary Locations and Meta Location

  • Investors’ primary location was chosen as the first in the “locations” attribute.
  • Meta location was determined by manually merging primary locations.
  • There may be some inconsistencies or misrepresentation of some investors’ location.

Connections

Connections are drawn by finding the number of co-invested companies between two investors. For example, if “investor 1” and “investor 2” both invested in “company A” and “company B”, there will be a link drawn between them with weight “2.”

The Network

Both number of followers and number of companies invested have some correlation with betweenness centrality score. One with number of companies invested is expected since the network was generated using the co-investments.

Giant cluster of Silicon Valley investors

I don’t know whether AngelList data is skewed toward Silicon Valley investors or many investors list SV as a primary location even if they don’t live there but SV investors take large majority and they are very central. They are well-connected to pretty much every group and co-mingled with the second largest group, NYC/Boston investors(teal color).

David McClure and 500 Startups because of their number of investments, have the highest betweenness centrality scores and pretty much all other centrality measures.

Investors in within Silicon Valley region

Within Silicon Valley, there is no distinct sub-groups based on smaller regions.

Silicon Valley investors acting as hubs

There are many examples of SV investors acting as hubs to other regional groups of investors. The most prominent one is Brad Holden(bottom right) who is connecting a very well-connected group of Los Angeles investors.

Joshua Baer is a Texas based investor who is connecting many investors in the same region.

Another example is an investor who is based in a region outside of Silicon Valley but has made many investments with SV investors acting as a hub to regional investors. Joshua Baer(top center) and Bill Boebel are both are based in Texas but have many co-investment connections with SV investors are connecting other Texas based investors.

Ideas for Further Analysis

I wish I was able to get some temporal information to do more advanced analysis such as

  • A group of investors acting as flocks – How does certain attributes of investors inform/motivate other investors to act together?
  • How does information about startups disperse between investors?

LA, home for entertainment, what about UI design?

An Example of Bad UI
An example of Bad UI

It was summer 2004 when I moved to LA for college.
Since then I have been attending some meetups regarding application development(LAMP, RoR, etc), UX(User eXpereince), Funding events, pretty much anything to do with internet and business.

LA has been called home for many entertainment companies and some tech companies such as PriceGrabber, MySpace and Shopzilla.
There are more tech companies being founded in a rapid pace with help of events like Twiistup and Dealmaker Media.
But in my opinion, LA isn’t the best place for startup. The primary reason being not enough funding for tech startups.

Despite the fact that there isn’t enough funding for tech startups, I want to bring out one possible reason. Lack of good UX architect/designer.
I am a firm beliver of good UI/UX. Consumers are getting smarter (or spoiled?) by good UI everyday. For example, people are choosing iPhone apps by looking at UI. There are 1572991029 RSS feed application on Apple iTunes App Store and only handful good looking apps are making decent to great money.

Maybe I didn’t do my research, but the only decent sized UX consulting firm in LA is HUGE and I do not know any great UX architect for web application personally(If you happen to know one, please let me know).
I think this has some or greater impact on LA tech scene. LA needs great UI/UX designers/architects to support startups. Most startups can not afford UX consulting firm. We need more individuals! This will lead to better applications which leads to more adoptions from users.

Do you agree with my point? or not? I want to hear from you. Drop me a line.
