Bad. Ass. Advice. (for entrepreneurs)
Team risk: can these people work together to build a huge business?
Technical risk: can this be built in a reasonable timeframe and with reasonable resources?
User risk: will people actually want to use this?
Revenue risk: will people actually pay for this?
Scale risk: will people use or pay for this in large numbers?
Partner risk: will any required strategic or distribution partners come on board?
Customer risk: will they be able to sell to important customers?
Funding risk: will anybody else fund this (esp seed stage, for many investors)?
