I'm not affiliated, and the end is kinda corny, especially if you are a typical skeptic/rationalist Silicon Valley type. It's not exactly how it happened with SpaceX, but there are quite a few parallels:

EDIT: In case you are not sure, it's a fiction book. It's interesting because it presages some things SpaceX did later.
The book has paper-thin characters whose whole purpose is to explain and counter-point a long list of technical explanations for why the company, vehicle, and manufacturing processes were designed the way they were. The book has a copyright date of 2005.
I really enjoyed reading the book.
The book, in the front, has a section called "Blurbs for The Rocket Company", which has some comments left by John Carmack of Armadillo Aerospace, Jeff Foust of The Space Review, Gary C Hudson of HMX, Inc, Eric Laursen of International Launch Services, and Elon Musk.
To quote the blurb directly: "This is an interesting approach to the greatest problem in space exploration: the cost of getting there" -- Elon Musk CEO, Founder Space-X
There was a self published Sci-fi book from a few years back, where some dot-com billionaires funded a "big and dumb" design philosophy reusable two stage to orbit rocket. It also used aluminum computer aided machining and friction stir welding to increase seam strength and lower structural weight.
