I worked at Epic Games for two years. This is real, and the strategy behind it is smarter than most people realize. Tim Sweeney has spent nearly two decades buying North Carolina forest land. 50,000+ acres across 15 counties. He’s now one of the largest private landowners in the

Actually found a reasonable explainer on Reddit why Docusign needs 7,000 employees: ▫️”Lets say most people use the product 5 times a year, but 1% of people sign something with it 10 times a day. US alone, that's 5*250m + 10*365*2.5m. About 10 billion in the US.” ▫️Assume US is

This dude lives in isolation, reportedly has no cell phone, a 24/7 security detail and even had white-noise devices installed on his office windows to block laser based eavesdropping. He's also the CEO of one of the most invasive surveillance companies in the US? Irony much?
