"As a company grows, everything needs to scale, including the size of your failed experiments. If the size of your failures isn't growing, you're not going to be inventing at a size that can actually move the needle. Amazon will be experimenting at the right scale for a company of our size if we occasionally have multibillion-dollar failures."

On why big companies must take big swings.

"Wandering in business is not efficient … but it's also not random. It's guided – by hunch, gut, intuition, curiosity, and powered by a deep conviction that the prize for customers is big enough that it's worth being a little messy and tangential to find our way there." Wandering is the counter-balance to efficiency, and non-linear discoveries require it.

Third-party sellers grew from 3% of physical GMS in 1999 to 58% in 2018 — a 52% CAGR vs. 25% for Amazon's own first-party business. Amazon won by building the best tools (FBA, Prime) for sellers to compete against itself.

The opening statistical reveal of the letter.

"No customer was asking for Echo. This was definitely us wandering. Market research doesn't help. If you had gone to a customer in 2013 and said 'Would you like a black, always-on cylinder in your kitchen about the size of a Pringles can that you can talk to and ask questions,' I guarantee you they'd have looked at you strangely and said 'No, thank you.'"

Customer obsession isn't enough: "The biggest needle movers will be things that customers don't know to ask for. We must invent on their behalf. We have to tap into our own inner imagination about what's possible." AWS itself is the proof — no one asked for it.

The Fire Phone failed, but its team and learnings were redirected into Echo and Alexa. A single big winning bet can cover the cost of many losers — which is the case for taking large-scale risks as a big company.

On reframing failure as input to the next bet.

From the 1997 letter: "You can work long, hard, or smart, but at Amazon.com you can't choose two out of three." Setting the hiring bar high is described as the single most important element of Amazon's success.

On the $15 minimum wage: "We had always offered competitive wages. But we decided it was time to lead – to offer wages that went beyond competitive. We did it because it seemed like the right thing to do." Bezos publicly challenged competitors to match or exceed it.
