Pricing power in vertical SaaS: why narrow workflows compound faster.

Pricing power is the right to raise prices annually without measurable churn. Vertical B2B SaaS earns it faster than horizontal SaaS because the workflow is narrower, the competitor set is shallower, and the buyer feels the pain directly.

Multi-product B2B SaaS: when bundling compounds, when splitting is the honest answer.

Bundling B2B SaaS products only compounds when the buyer, the workflow, and the data model overlap. The Cobalt Glacier framework for deciding when to bundle a roadmap, when to split it, and when to bundle only the buying motion.

How we underwrite a software acquisition for a 25-year hold.

Three filters every deal has to clear before we model it, what changes when the hold period is twenty-five years, and why the discipline is in what we walk away from.

The first 100 days: what we change after a Cobalt Glacier acquisition (and what we deliberately don't).
