I first heard this analogy in the 1990s with regards to the dotcom boom.

I've found that every bit of good investment advice I've seen is very applicable to startups. This is great training for weeding out ideas and thinking about business models.

So, all of the popular investing books are useful in this regard. For instance, you'd think Warren Buffett would not be useful for a high tech startup, but I find his philosophy extremely compelling when thinking about the startup business. (To that end, I recommend buffettology)

Further, all of the metrics one uses to evaluate the prospects of a company one is going to invest in by buying shares, are also applicable to valuation of your business when selling shares to investors, especially in later rounds when you have revenue and hopefully profits.
