Nice little write-up on Squarespace from Fortune's Miguel Helft:
Casalena raised $30,000 from his father and spent $20,000 on servers, which he installed himself. Another $2,000 went to designing a logo. On Jan. 6, 2004, he put out a press release announcing his offering. In the first year, he made about $50,000. The following year, revenue had climbed to $250,000. “It was a very successful project, but not really a company,” he says. In the third year, he hired a contractor and a person to deal with customer care, but he was still doing most of the work – including answering tens of thousands of customer tickets – himself.
Yes, I run Heycupertino! on Squarespace and don't mind saying I love the way it looks and works given the very minimal time invested in getting this shindig up and running.
