17 Startup Mistakes

John Osher is the epitome of the “serial entrepreneur”. After selling his toy company – CAP Toys – to Hasbro in 1997 for more than $120 million this is what he did:

“I decided I’d make a list of everything I’d done wrong and [had] seen other entrepreneurs do wrong, I wanted to make a company that didn’t make any of these mistakes. I wanted to see if I could come up with the perfect company.”

He then produced 17 Mistakes Start-Ups Make and personally used the list to create another company he later sold to Procter and Gamble for $475 million.
