Eric - I've worked for NASA, ATT, IBM, HP, Amazon, and Google, not to mention a couple of startups that I started in between. None of them (except the startups, but they were brief) stayed true to their original mission. I haven't read your new book, but IMO, it's because the founders leave and the next leadership don't share the vision or values of the founders in the same way. After all, a company is a collaboration among people who want to make a contribution. When the people change, the company changes. It's inevitable.
That said, you seem to have archetypes above Costco, Patagonia, and Novo Nordisk that avoided it.
Can you comment on not what it takes to build such a company, but rather how to transform companies like those that I worked for into ones that resist gravity? Or is it too late?
