The service

The service a 10,000-life group gets. Built for yours.

Someone answers.

Support with full context on the med and the plan — no phone trees, no "let me transfer you."

We reach out first.

Refills, lower-cost options, coverage changes — members hear from us before they have to ask.

HR gets their job back.

Pharmacy questions come to us, not your people. That's the point.

Built for consultants, not around them.

Faster RFPs, real-time analytics, and your consultant's strategy implemented as designed — no redlines.

Groups your size have never been anyone's priority. They're our entire company.

The insight — routing, not pricing

When a small group's drug spend is high, everyone assumes high prices. Usually it's bad routing.

Cost-plus pharmacies Digital pharmacies Biosimilars Legitimate assistance programs The traditional rebate network

So the real question isn't "who negotiated the better price?" It's "which channel wins on this drug, for this member, under this plan — right now?"

That's the engine RxDune runs underneath every plan.

Price it.

Send us your claims file. We model expected savings from your own data — not a benchmark, not a percentage on faith.

Live plan spend in a real-time dashboard — every dollar, visible, as it's spent.

Prove it.

Every quarter: actual savings against the baseline modeled from your own claims.

The model

We only make money one way.

A flat admin fee — and nothing else. No percentage of drug spend, no kept rebates, no pocketed spread, no pharmacies we own. Everything passes through at cost, and the fee is disclosed in every proposal.

When this happens… A traditional PBM RxDune

Drug prices go up

Their revenue goes up

Our fee doesn't move. The member gets rerouted.

A cheaper channel exists

Using it costs them revenue — so they often don't

Our fee doesn't move. Your cost goes down.

A cheaper option gets blocked

Their revenue up. Your cost up.

We don't block it. We have no reason to.

Our revenue is an administrative fee, not a function of drug prices. Every dollar we save you stays yours.

Service

Your employees stop bringing pharmacy problems to HR.

The app shows members their real costs and lower-cost options at the point of decision — and a patient-services team, backed by AI with full context on the med and the plan, reaches out proactively instead of waiting for the phone to ring.

We sell through brokers and consultants — always, never direct.

Every channel pre-wired, RFPs back in near-real-time, and the support burden off your desk.

From the founder

RxDune started inside PBM RFPs — the process that decides which pharmacy benefit a group gets. Smaller companies rarely had options built around them. So we built Dune — a Dynamic Utilization & Navigation Engine — designed for them from day one.
