Zac Sprackett
Co-Founder & CTO, Brief
Zac built the engineering systems that scaled SugarCRM to a public-market company. He writes on the architecture that makes Executive Intelligence possible and what separates it from retrieval-first systems.
Background
Zac built the engineering systems that grew SugarCRM from an open-source project into a public-market business. At Brief he leads the team building the World Model of Work, the maintained, evolving substrate the Executive Intelligence category depends on.
What he writes
Zac writes on three themes across the Papers.
The first is why retrieval is not enough. A system that reconstructs context from documents each session cannot anticipate what the executive needs before they ask. Anticipation is a property of a maintained, evolving model. It is not a property of search.
The second is the architecture of follow-through. Owning whether an executive's decisions, commitments, and goals carry through requires a model that lives outside the language model and persists between sessions. Language models reason over context. They do not carry it. The substrate that makes follow-through possible has to be maintained independently, and Zac describes what that architecture looks like.
The third is privacy as architecture. Executive context is more sensitive than passwords or documents. It reveals how a leader thinks, who they trust, and what they are about to decide. The architecture Zac describes makes that context structurally inaccessible to anyone but the executive. That is not a policy. Policies can be rewritten. An architecture cannot grant access it was not built to grant.
