As much as I'm a fan of Emacs, I don't think a .emacs file had much to do with that startup's success. He just wanted to see the UX and features that were possible for a particular purpose, for ideas and competitive analysis. But I did opensource a minority of the bits. :) https://www.neilvandyke.org/emacs/

Not unless the startup was Amazon, which used emacs as an application platform for all their customer support :)

Totally believeable. I had one research prototype that invoked an Emacs process for every Web CGI request. To get that kind of R&D rapid development productivity, I then had to start building out libraries for Scheme. :)
