This is more of an open question than an answer. Maybe a track for someone at TRU London?
If for example you are a media platform, trying to change the model from the old classified model to a performance based model does it make sense to hire sales people from the businesses you are trying to disrupt? If you hire enough of them won't you end up with replicating a similar culture?
Or is it simply that the buyer is still the same and that's what matters. The classified sales people know who they need to sell to and how to get past the same old gatekeepers and in reality a salesperson can sell whatever they are given (assume same industry different package).
It's more of a question for recruiters really but someone once told me that it's the quality of the questions you ask that matter rather than the answers you give!
