His wife was playing the role of co-founder. She believed in him and helped him make the MVP.
Kudos to the guy for the initiative, but we are wrong to assume the janitor is in a weak and powerless position. You can work in a factory where you don't see any of the building apart from the walk to your station and the walk to the tea room. You just do your shift operating a machine.
The janitor isn't so intensively over-worked, not physically tied to a machine on a production line. There is scope to travel about the facility and time to observe. There is also scope to be on first name terms with everyone. But most managers would never hire anyone with an entrepreneurial brain into such a role.
Also by being outside any power structure the janitor has nothing to lose and everything to gain.
This story is also telling because of how people in America find it so inspirational. They are chips, a popular junk food item made of corn!!!
Some perspective is needed on that. No atoms were split. If you had two kids, one grew up to be the inventor of a new chips flavour, the other to be a foreign language teacher, which one would you feel best pleased with? Being happy and down to earth isn't good enough though, in America there has to be a rags to riches story for one to be deemed successful.
