This CEO built his company for $60 in one weekend—it brought in $80 million last year: 'You can copy my model'

Noah Kagan's book "Million Dollar Weekend" isn't about getting rich quick.

The multimillionaire founder and CEO of discount software firm AppSumo would be the first to tell you that he didn't become wealthy overnight.

He paid a developer in Pakistan $48 to build a website with a PayPal button and spent $12 on a domain name. One weekend, $60 down, and he was up and running. The rest, as they say, is history.
