Mad Fientist

Tax optimization for the FIRE-minded.

Newsletter FIRE Irregular Updated Sep 2026

About

Mad Fientist focuses tightly on the tax-optimization side of financial independence, using detailed modeling to show how account structuring and withdrawal sequencing can meaningfully speed up an early retirement timeline.

The tone is technical, spreadsheet-heavy, and willing to spend an entire piece on something like the Roth conversion ladder in more depth than most FIRE content bothers with. It's best for readers who already understand the basics and want to optimize the mechanics, not be introduced to the concept.
