There's a picture going around in the web from a presentation, comparing Turkish Airlines and WhatsApp. There couldn't be a more apples-oranges-comparison, but it is bizarre and intriguing anyhow:
Founded 1933 (TA) vs. 1999 (WA)
Employees 23000 (TA) vs. 55 (WA)
Market Cap 4.3bn (TA) vs. 19bn (WA)
Assets Planes (TA) vs. Servers (WA)
Function transports people (TA) vs. transports messages (WA)
I disagree with the assets thing because I think that's an old-school, physical-asset-perspective for balance sheets, as the true assets for WA will of course not be servers, but maybe a) the address books of people and b) their 55 engineers who serve 900mn users. And whoever now thinks that "old economy" like airplane companies are dead and only software will survive is a naive weirdo. But it is still amazing to see how few people in how short a time can create something that we trust so much more to be creating value than transporting millions of people safely and comfortably around the globe.
