As a capital & investing term, Buy-and-Build means a capital concept. Settle what it covers before the planning starts.

How it works

Here is the short version.There is no single setting for Buy-and-Build. It bends to the audience, the channels, and the wider plan.

Buy-and-Build is not a switch you flip. It names a moving idea, and the way it plays out shifts with the setup. A lean team running one paid channel applies Buy-and-Build differently than a brand running ten. Use Buy-and-Build loosely and teams pull apart; pin it down and the math lines up.

One rule always holds. Settle the scope of Buy-and-Build up front, then build the plan. Get it backwards and Buy-and-Build becomes a word everyone uses and no one shares. Worth a slow read.
