I used to work for a firm where I went up against Tribal in a lot of bids. They're very public sector focussed, as they say, but within that their expertise is heavily concentrated around the LEA education sector and the housing sector. There are some consultants with local government expertise (not a huge capability area for Tribal yet), but central government/health/NHS/regeneration/etc. are not fields where they have much of a track record. If you have experience in those areas, I expect they would be keen on you and you could become a market lead as they don't have many people with the appropriate skillsets.
