I just came across this story and still can't believe how quickly everything can fall apart. Eduardo Saverin—one of Facebook's founders—walked into the office one day thinking everything was going according to plan. He was the CFO, the guy in charge of the finances. But when he left, nothing was the same anymore.

The crazy part? Mark Zuckerberg and the others had just pushed him out of the company. His shares—over 1.3 million, representing about 34.4% of the company—had been secretly diluted down to a tiny 0.03%. All without his knowledge, all orchestrated behind the scenes.

I try to imagine how that must feel. You invest your money, your time, your trust in a friend. You build something big together. And then, without warning, you're simply erased. Not just from the company— from the story itself.

This is one of the wildest founding stories I know. A classic example of how quickly friendships in the tech world can break down when it comes to power and control. Mark Zuckerberg kept the control, and Eduardo Saverin became a footnote. The lesson? In the startup game, you need more than just a good idea and a friend—you need a damn good legal team.
