Liquid Death didn’t lecture teens about sugar.

They cast Peter Dinklage as a radioactive mutant to do it for them.

And it worked better than anything Pepsi’s ad team has produced in years.

Here’s the thing. Everyone noticed the creative choice. What I kept coming back to was the structural decision underneath it.

Why does borrowing someone else’s credibility work better than building your own from scratch? Why does a cult franchise with a devoted niche fanbase outperform a celebrity endorsement with mass reach? And why can Liquid Death pull this off when Coca-Cola structurally cannot?

That’s the Borrowed Authenticity pattern.

In this breakdown I walk through the $5 million campaign, show you where the pattern has worked before (Old Spice, Dollar Shave Club, Poo-Pourri), and where brands have tried it and gotten burned.

Then three diagnostics to run before you try it yourself.

Not gonna lie. I went into this thinking it was a great creative case study. I came out thinking it was a structural business strategy disguised as an ad.

Apply the Borrowed Authenticity pattern to your own brand.

I built a GPT that walks you through these diagnostics against your actual business and surfaces the cultural assets your audience already trusts.
