This was a simple example to illustrate a point. A more realistic example would be: owning 100% of a company making $1M/year is better than owning 40% of a company making $100M/year where investors put in $500M with a 4X liquidation preference. This case is even clearer here, but not quite as easy to parse.
Modern VCs allow founders to retain a large "percentage" of their company in stock or other ownership terms, but they use liquidation preferences and other mechanisms to effectively increase their financial leverage.
Fundamentally these kind of comparisons are not really relevant. The $1 million/year business is not even in the same universe as the $1 billion/year one, nor are the motivations of the typical founders.
no joke: I wouldn't criticize someone who
1. Founded a company
2. Had the company under his or other people management go to 100m USD
3. Kept some equity, even 1%
Obviously if giving up 99% is what enabled you to get to the 100m, then sure, it could be considered worth it. But if we look at virtually any startup with a high valuation, the founders always manage to maintain more than 1%.
