Jason Goldberg is the founder & Chief Executive Officer at Fab.com. He and his cofounder have built Fab.com from a near failed start up which they pivoted into a major online design goods outlet business with a run-rate of more than $150 million in sales in 15 months. Two years go Jason posted a note on the 57 things he had learned in building start ups and pivoting Fab.com. He updated that last week to the 90 things he has learned since. If you are involved in a start up - its a tad longer than HP's 10 golden rules - but its has some good advice throughout the list. Worth a read if you are invovled in start ups or managing a business.
