In the non-fiction sphere they could do worse than to read:

- Snow Crash by Neal Stephenson

- Neuromancer by William Gibson

Both books have had a huge impact on hacker culture, as well as doing a good job of documenting it. They will convey aspects of the culture that more traditional startup books can't convey - hacker language, attitude, motivation etc.

They are both great reads too.
