Most posts on Denali Llama are written for a single sitting. Fifteen minutes of reading, one frame on one specific question. That's the right format for most of the work.

The other ten percent doesn't fit.

Series is the section for multi-part deep dives — the questions that need three thousand words, or seven, or sometimes the better part of a whitepaper. The structural arguments. The frameworks that span more than one decision. The pieces I'd otherwise have to cut in half and water down to fit a normal post.

The inaugural series, published in five parts between January and May of 2026, covers the operational disciplines that separate MVNOs that scale from MVNOs that don't:

  • Billing operations and the platforms that get them wrong.
  • Rate plan optimization — which is really rate plan architecture, because the rate plan is the product.
  • Launch readiness, including the diligence work that should be complete before any carrier signature is sought.
  • Regulatory compliance, which most founders treat as a back-office concern until it becomes the only concern.
  • Customer lifecycle economics, with a working model for how the unit economics actually compound across years two through five.

You can read the series in order — the pieces are sequenced to build on each other — or pick the paper that maps to whatever you're sitting with right now. Both work.

Future series will follow when the question is large enough to warrant the format. Topics under consideration include MVNA economics at scale, the platform-consolidation trajectory in MVNE, and the operational playbook for the second-year decisions that compound. None of those are short.

If you're new to the publication, Fundamentals is a cleaner starting point — the series here assume domain familiarity. If you're already inside the work, the inaugural series is probably where you want to be.
