I'm getting the feeling they had too much cash too early and didn't have a good balance of hacker founders. They had two (excellent) UK web agencies working for them that wouldn't have come cheap.
Plus they were working in Clerkenwell, London (around the corner from my work offices) and rent around here isn't cheap. Did they really need 12 employees to launch?
I think the story is a little strange with the divorce forcing a freeze on the invested money. It sound more like the investor didn't want to pay, as there are 10 other similar products/sites and their application cost much but didn't deliver much.
