I and others read his post carefully and agree with it/believe it. The 100% retention rate obviously just means he isn't seeing churn - if he doesn't do anything he won't have to fill the seats that are filled today on his team in four months due to churn. It's obvious that that part wasn't literal: he told us of the experience of employees leaving (to go to competitors, and taking his trade secrets / competitive advantage with them - and that the people who did so had superlative/"ivy league" credentials.) nothing wrong with his post.

By the way 7 figures covers everything from 1,000,000 to 9,000,000 - so I read it as being barely seven figures in profit, or I would accept if the actual bottom line profit were 700k-1M (so that it's a bit of an exaggeration to call it all "profit"). However the top line (sales) has to be (well) over 1m or I am unhappy/consider it too much embellishment.

OP - what does the top line look like? Roughly how many employees do you have?

I laughed, I'm pretty sure it's satire. Right?

If only I had taken the advice in life I dismissed so quickly out of disbelief, just like you're doing now, I'd be where I am so much faster.

It's possible to have a %100 rate when you haven't been around long.

100% owner also means they bootstrapped and were a solo founder.
