Yeah, Jeff Bezos took his idea for an online bookstore from working as an employee at DE Shaw and delivered way more value by systematically derisking the business over decades.
There was a market worth many trillions: online retail. When Bezos created Amazon, owning part of that company was very risky and therefore Amazon was nearly worthless. Now anybody can buy a share of Amazon. Bezos was compensated for the value he created by derisking.
