The operating system for people who lead like engineers.
TAZZUBA applies Stoic logic and autonomous systems to leadership — separating what's yours to control from what isn't, so nothing gets processed twice.
The Framework
Two Layers, One SystemAlgorithmic Stoicism
Classical Stoic thinking — Epictetus, Marcus Aurelius, Seneca — rebuilt as explicit if/then logic for the mind under pressure.
Every incoming event runs through one filter: is it within my control? True, and it gets your attention and effort. False, and it gets released before it costs you anything. No event gets processed twice.

If Algorithmic Stoicism governs the mind, HOE governs what's around it — the workflows, the teams, the systems a leader is responsible for.
It treats routine execution as something to design once and automate, often with AI agents handling the procedural work, so your attention stays on decisions only you can make.

The Architect
FounderTAZZUBA is founded and written by Derrick Sekiziyivu — applying systems leadership, cognitive engineering, and hands-on AI agent development to the everyday problem of running a team, a business, or a life without burning out on things that were never yours to control.
The books come first. The services, the institute, and the tools are built on top of the same core filter — nothing added that doesn't reduce friction somewhere real.
