The Parallel Contracts Model: A Post-Mortem
What the model made possible, where it became expensive, and why focus won.
Parallel contracts can create useful leverage for a senior technical leader. They expose you to different product problems, architectures, teams, and business constraints in a compressed period of time.
The tradeoff is context switching. Every serious technical role carries invisible load: architecture memory, people decisions, production risk, customer promises, and the need to be available when judgment matters.
Over time, the question shifted from "can this be done?" to "is this the best operating model for the kind of CTO work I want to do?" For deeper company-building work, focus became the better answer.
The lesson was not that optionality is bad. It was that optionality has a carrying cost, and at some point concentration produces better decisions, stronger teams, and more durable outcomes.
