The Perfect Store by Adam Cohen deserves a three plus stars, and an additional one for its beautifully written (and emotional) final chapter. The book chronicled ebaY's development, from a raw idea of "people are basically good" to the largest online auction website, that eventually made its founder(s) multi-billionaire(s). I love eBay and have approx. 500 stars on the website myself - at some point I was perhaps ebay addicted, but I only became a member in 2010, so it's great to learn about the company in details.
I found it quite fascinating how eBay succeeded in fending off competitors, both upstarts and much larger and threatening ones such as AOL, and Yahoo!. It is interesting to know that at the peak of the dotcom bubble, Yahoo! and eBay were in talks of an M&A. The market cap of Yahoo! was three times larger than eBay then - and after the burst, Yahoo! lost 95% of its market cap, while eBay only lost 50% of its valuation. The business model of eBay was so much more sustainable, with strong cash flow and super high gross margin - it was profitable since month one. Yahoo!, not quite. The Yahoo! as we knew it, well... And the rest was history.
I think that a reader with his/her interest in strategy would find the book interesting. It didn't focus on the financials of eBay though - I know that the company was financially sound, that it put its VC money into a bank for it didn't need it, but nothing much else.
It was sad to read in final chapters when founder(s) left the company after a transition period after its IPO, and that the company became just another corporation, ie. driven by bottom line (maximizing its shareholders value, or simply put, being corporate greedy, etc.)
A good read.
