That is very good advise.

The junior marketing person you are working with at one company a few years later may be head of marketing at a much larger company.

It can also work in reverse when your contact moves on and their replacement comes in with a pre-existing relationship with a competitor. Then it's nothing but work to keep them - same can happen when a small business sells and you have a new owner to build a new relationship with.

Have a client that is in the process of selling to what will be the fourth owner since I built their management software 12 or so years ago.
