The single biggest reason why startups succeed

tl;dl: Timing.

The rank ordering was Timing, Team, Idea, Business Model, and Funding.

Also, keep in mind that the scores were assigned by Bill Gross, qualitatively, and so I wouldn't necessarily consider this a very scientific survey. It does roughly match findings by a16z and YC, though.

Can someone please take the team and tell us what it is?
