这些创始人称为1000客户个人- and They'd Do it AgainGeoffrey Woo and Michael Brandt personally reached out to customers after orders of their product was delayed. It was weeks of work, but they don't regret it. Read on to see why.

In 2015 Nootrobox was flying high from stories about its flagship product -- a pill supplement called RISE designed to enhance cognitive performance -- that appeared in a series of media outlets such asThe New York Observer. Not even a year old, the San Francisco-based startup had the kind of marketing boost every company dreams of. Then it ran out of product.

"We were very excited about the press coverage, which blew orders through the roof," recounts founder and COO Michael Brandt. "We had pulled the trigger on a purchase order to replenish supply and tried to get our supplier to move faster when the press stuff happened. But you can't just snap your fingers and get a product like ours made faster."
