The fourth wall

Why this exists.

This site is a demonstration. It was built in one night, on July 7, 2026, to make an argument that is easier to show than to say.

Cost Plus Drugs publishes its actual acquisition cost plus a fixed 15% on every one of roughly 2,500 medications. That price list is usually described as a pharmacy. It is also something else: the only public, continuously updated record of what American drugs actually cost — which makes it the raw material for a publication nobody else can produce.

Researchers already treat it that way. Harvard used it to benchmark Medicare. Penn used it to benchmark employer insurance. The FTC's PBM reports document the same gap from the other direction. But those are papers, published months apart, read by specialists. Nobody has turned the dataset into what it wants to be: a running index — updated, ranked, readable — that becomes the reference the press, Congress and 340 million patients check when they want to know what a drug should cost.

The real version of this site.

  1. The Markup Index — the full catalog tracked against published retail prices, updated weekly, with an API and embeds for journalists.
  2. Briefings — data-driven reporting like the two demo pieces here: rankings, FTC-report explainers, state-by-state and drug-by-drug stories, each with sourced footnotes.
  3. The policy layer — testimony-grade fact sheets, so every drug-pricing hearing and news cycle cites this index by default.

Everything on this demo — the index, both briefings, the methodology — was researched, verified and shipped in one working session by Letter Leverage, an AI-native editorial studio. Every number traces to a source URL. That speed and that discipline are the product: we would build and run this publication end to end, under your brand or a neutral one, as a service.

The ask: thirty minutes. Nils Liedlich — nils@letterleverage.com. I'm at RAISE Summit both days.
