These types of article often list Jeff Bezos or Frederick Smith (Fedex) as examples. These guys were already millionaires when they started their company, I don't think they should be counted. There are enough solo startup founders who started from scratch in their kitchen/bedroom/garage, if look for them. No need to list less relevant cases IMO.

For what I know Bezos was a wall street worker, probably wealthy but no near millionaire. He borrowed 30k from his dad to start amazon.

He was a VP and from what I recall reading was making in the high six figures.

He was most certainly a millionaire and so we're his grandparents who owned a 25,000 acre ranch in Texas. Jeff had a silver spoon in his mouth from birth just like many other successful businessmen.
