Very early on, Jeff Bezos, founder and CEO of Amazon.com, envisioned a company that made money by delivering value to rather than extracting value from its customers. In order to do that, he wanted to be both the price and customer service leader for the long run. You can’t do that if you waste a lot of money. Jeff could have spent years auditing every expense and raining hell on anybody who overspent, but he decided to build frugality into his culture. He did it with an incredibly simple mechanism: all desks at Amazon.com for all time would be built by buying cheap doors from The Home Depot and nailing legs to them. These door desks are not great ergonomically nor do they fit with Amazon.com’s $100+ billion market capitalization, but when a shocked new employee asks why she must work on a makeshift desk constructed out of random Home Depot parts, the answer comes back with withering consistency: “We look for every opportunity to save money so that we can deliver the best products for the lowest cost.” If you don’t like sitting at a door, then you won’t last long at Amazon.
