What's the difference between smart money and dumb money?

Summary: Smart money is money plus the promise of help that's worth paying for, dumb money is money plus hidden harm, and mostly money is mostly money. Weed out the dumb money with diligence. Evaluate supposedly smart money with the smart money test. Finally, assume your investors are mostly money: unbundle money and value-add to get money on the best terms possible and value-add on the best terms possible.
