Agreed that I like the covers with the mountains on them. The covers with light bulbs and matches don't match well with the title "Unscalable" though I know their concepts match the concept of the book. The carabiner is very meh. I personally like the original mountain, though the floating one is good too.
Unscalable uncovers Silicon Valley’s lesser-known backstories of failure and achievement. Interviews (GitHub, Zenefits, DoorDash and more) showcase eclectic strategies and experiments, revealing the long and unpredictable road to startup success.
