>If you didn't think we were in the dot com bubble 2.0 and the re-emergence of the Pets.com strategy won't show you, I don't know what will. I wonder which one will get the superbowl ad. This is a silly, meaningless analogy. Every grown adult on earth was not walking around with a computer connected to broadband internet in their pocket in 1999. There were less than 500 million internet users total .
$600 million in venture capital... For dog walking. It's even more stupid than Pets.com because at least Pets.com was an ecommerce site so it could scale out. It doesn't really matter that Asia, Africa and Latin America have all come on line (I would bet that the 1999 internet was primarily Europe/US given its roots) if you're selling dog walking in California and New York now, does it?
There are around 80 million pet dogs in the United States. Let's say the success case for one of these companies is to capture 10% of that market -- 8 million dogs in need of walking every day or two or three. Let's say they can take in $5/month in revenue from 10-30 walks (it's probably more than this).
That's almost half a billion in revenue per year.
