Personally, I found it a bit fluffy. It pretty much boils down to:
"Data startups need three bodies (hustler, designer, prodineer). Talk to customers early. Here are the levels of knowledge: 1) data, 2) charts, 3) reports, 4) actionable analytics; higher numbered levels are more valuable."
Some other posts at www.datasyndrome.com are less fluffy on the same topic. The 3 founders one was written to suggest a 3rd founder to a startup. Data hackers tend to underestimate the importance of hustling and design.
