How operators apply it

Start here.First Lien is no fixed dial. How it behaves depends on your audience, your channel mix, and the strategy around it.

First Lien behaves unlike a fixed rule. An early-stage brand and a mature one will apply First Lien on different terms. The mechanics follow the inputs around it. Treat First Lien as a buzzword and the reporting misleads; agree on it and the numbers hold.
