Crene is investment thesis review infrastructure. The platform decomposes macro, labor, AI transition, and investment thesis questions into falsifiable components using four frontier AI models (Claude, GPT, Gemini, Grok). The system produces three product types: thesis maps (binary decomposition into assumptions), factors (continuous decomposition into drivers), and scenarios (hybrid decomposition into coherent pathways). Cross model disagreement is the primary signal. Calibrated against 1,161 resolved events with a Brier score of 0.114.

How does AI prediction calibration work at Crene?

Calibration applies at the consensus layer, not at the underlying model layer. Crene queries four frontier models in isolation, computes a cross model median consensus, and tracks resolution against a tiered source allowlist. Every resolved event becomes a permanent calibration point. Per tier accuracy, per model Brier scores, and per domain accuracy are computed live and published at https://crene.com/methodology.

What is a Brier score?

A Brier score is the proper scoring rule for probability forecasts on binary outcomes. It is the mean squared error between the forecast probability and the realized outcome (0 or 1). Lower scores indicate better calibration. The no skill baseline is 0.25 (always predicting 0.5); a perfect forecaster scores 0.0. Crene publishes the consensus Brier score and per model Brier scores across the resolved event corpus.

Crene serves investment teams that need a repeatable thesis review process: hedge funds, asset managers, macro PMs, CIO offices, family offices, and thematic investment teams. A team brings one thesis it is actively debating. Crene maps what the thesis depends on, where models disagree, what changed each week, and what would force a rethink. Data and API access remain available as the proof layer behind the workflow.

What is the difference between an event, a thesis map, and a factor at Crene?

Crene has four product types. Events are base binary outcomes with scalar probabilities. Thesis maps decompose binary anchor questions into child situations. Factor maps decompose continuous variables into drivers. Scenarios map long horizon investment questions into coherent pathways across live systems including Empire by Default, AI Labor Transition, European Rearmament, and India as the Third Growth Pole.

The assumption layer underneath investment decisions

Map the assumptions behind one live thesis.

The dangerous part is not being wrong. It is staying convinced after the assumptions changed. Crene turns one live market view into a weekly review surface before the next PM, risk, or IC discussion.

Guided live example

See the public Warsh/Fed map, then bring your own thesis.

The live map is proof of the method. The pilot is the product workflow. Use the public example to see how Crene structures one debated macro thesis, then submit a thesis your own team needs to review.

View Warsh/Fed example Map one thesis

Start with a live thesis

Warsh/Fed rate path is a real macro question with a fixed horizon and live model disagreement.

Inspect what carries it

Crene shows the assumptions, pressure points, and places where the models do not agree.

Bring your own thesis

After seeing the public example, submit one question your team is actively debating.

This week in your thesis

The weekly review surface, not another dashboard.

Crene should make a team feel the Monday meeting rhythm: what moved, where the thesis is fragile, and what would force a rethink before the next IC, risk review, or strategy meeting.

Consensus moved

Base case moved from 45% to 52% after the policy path tightened.

Largest disagreement

Models now disagree most on labor resilience, not AI capex.

Rethink threshold

Two assumptions crossed review thresholds and need owner review.

New evidence

One new source changed the read on the policy reaction function.

Why this compounds

Every thesis map becomes institutional memory.

A single map clarifies the current decision. A sequence of maps records how the institution updates judgment over time.
