Yeah there’s a recruiting firm that literally hires ex-CEOs, puts them on the bench, then searches for their next “assignment”. They pay these people to golf until they place them.
I wouldn't expect to see it for sales so much, as it would mess with the incentive structure and you kind of want your salesfolk to be "all in". Same goes for CEO or COO - they might have a small portfolio of non-exec board memberships (or similar) on the side, but it's hard to do a good job if your primary focus is split between multiple distinct businesses.
