Tractis is a company I am particularly interested in. Tractis is aimed to facilitate the negociating and signing of contracts, online. Signing contracts online is quite time-saving, however it is very difficult to check identities. Tractis deals with the processes, technologies and legal frameworks to give the user the ability of signing online, with confidence.

BBC World has bought 75% of Lonely Planet, a very cool company founded in 1972 by Tony and Maureen Wheeler. Tony is a London Business School Alumnus.
It is really nice to see how London Business School is being known by entrepreneurs too, and not only by finance guys.
