Yesterday's Business Week describes "How American Andrew Paulson is building a growing Internet empire in Russia".

Paulson founded SUP in the summer of 2006. "That October, he signed a licensing agreement to manage [Live Journal's] Russian-language pages." In December 2007, SUP acquired Live Journal from Six Apart. Shortly thereafter, Jason Shellen (who was at Pyra Labs, the developers of Blogger) joined as VP of Product Development.

The Business Week article is worth a read. I also found an interesting video interview of Paulson at Intruders.tv (in the UK).
