Not us. Currently we are working unfunded, so the cost to purchase the hardware and upgrade our home internet service to be reliable enough to support a business server was too high. You would also have to worry about fault tolerance yourself, so then purchasing backup hardware (drives, machine) yourself (and preferably storing offsite) then factors in.

In the end, we went with Amazon Web Services while we build our prototype, etc. I spent an evening getting things set up initially on it (still more to learn), but they have a free usage tier now so there was/is no cost to keep our site there until our usage justifies it. Hopefully by then we'll be making money and can cover the cost.
