Turn one important thesis into a
governed Decision Record.
SigmaX helps advisors, family offices, investment committees, and diligence-heavy teams transform a thesis into a living evidence system — visible, challenged, rehearsed, monitored, and frozen into a reviewable record.
Human-governed · Evidence-linked · No AI capital authority
One thesis. Seven governed artifacts.
Every Sprint produces the same governed structure — the building blocks of the SigmaX Decision OS, assembled around your thesis and delivered as a reviewable package.
Thesis Passport
The canonical identity of the decision: thesis, owner, assumptions, review state, and evidence posture.
Evidence Spine
The traceable chain of supporting and contradicting evidence.
Contradiction Lens
A focused view of what could weaken or disprove the thesis.
Scenario Forks
What-if branches that rehearse assumption changes before action.
Drift Triggers
Review signals tied to evidence, assumptions, or mandate movement.
Council Brief
Majority view, dissent, missing evidence, and next review action.
Decision Record
A frozen, reviewable record of what was believed, why, what changed, and what a human decided.
Frozen, dated, and defensible.
The Decision Record captures what was believed, why, and what a human decided — a record you can stand behind in committee or review.

What a finished Decision Record looks like.
- Thesis
- “Real rates stay elevated through the next two review cycles; duration-sensitive allocations remain under pressure.”
- Evidence posture
- Mixed — measured macro data + derived positioning signals; one unresolved contradiction.
- Contradiction
- Official guidance (“higher for longer”) vs. forward markets pricing earlier cuts.
- Scenario considered
- Base: rates plateau (thesis intact) · Sensitivity: accelerated easing (thesis sensitive — review immediately).
- Drift triggers
- A declared policy pivot · real yields roll over two prints · guidance/market gap exceeds band · client mandate change.
- Council Brief
- Intact under base case, sensitive under accelerated easing. Hold the thesis, monitor triggers, force a review if any fires. No capital action recommended.
- Decision Record
- Maintain the thesis under governance. No allocation change is directed by this record. Frozen + dated, review at trigger or cycle boundary.

SigmaX does not make capital decisions for you.
AI helps organize evidence, surface contradictions, rehearse scenarios, and prepare review artifacts. Humans retain decision authority.
- No AI capital authority
- No trade execution
- No performance guarantees
- No unsupported numbers
- No client data in public demos
- Every output is evidence-linked and human-reviewed
Questions, answered plainly.
- Is this investment advice?
- No. SigmaX provides evidence-governance and decision-support workflows. Human users remain responsible for their own decisions.
- Do you manage money?
- No. The Decision Record Sprint is not a managed-account, fund, or execution service.
- What do I need to provide?
- One thesis or decision your team wants to review, plus any supporting materials you want considered.
- Can this become an ongoing workspace?
- Yes. Sprint clients can convert into Team Decision OS access.
- Is my data public?
- No. Public demos use sample data. Client work stays workspace-scoped and private.
