I've come across this company because they are advertising in Tube stations at the moment, so I thought I'd have a look.

Interesting.. they seem to do very similar things to the kind of stuff I am experimenting with (see my IM bots for surveys or bbc schedules), but in their case they are working with the Amazon web services.
They also seem to have a travel-related bot at travelmessenger.co.uk.
