# sig.ai

> sig.ai builds evidence-first data and AI systems for marketing intelligence, operational decision support, and owner-dependent business handoffs.

## Method (citable definitions)
- Knowledge = Ontology + Facts. An ontology is a working map of how a business actually runs; facts are evidence attached to that map, each with a source reference.
- Insight = Reasoning over knowledge. Every claim traces to sources; without evidence the honest answer is "unknown."
- Action = Insight combined with explicit goals and constraints.
- Decision = f(ontology, facts, goal, constraints) — and the decision is always made by a person. AI agents draft and propose; humans decide.

## TransferOS summary
TransferOS helps under-LOI, near-close, and first-90-day buyers test whether seller operating judgment can be reconstructed from evidence before that informal memory disappears. Key-Person Diligence starts with data rights, evidence density, representative cases, owner dependency, and targeted correction paths.

TransferOS is not a generic AI SOP generator and does not request confidential records through its public application. It is not legal, tax, valuation, quality-of-earnings, broker, or HR advice.
