Stratum — Strategic Ground Truth

Your strategy is a hypothesis. Your assumptions are invisible.

You have OKRs. Dashboards. Risk registers. Compliance checklists.
A beautiful deck from Q1 that everyone already forgot.

But nobody tracks what must be TRUE for any of it to work.

"We'll win mid-market on simplicity."
Based on what belief?
"EU customers will pay a sovereignty premium."
When did we last validate that? Who owns it?

Six months later the bet fails — and nobody can name the assumption that broke.

That's not bad execution. That's flying blind on beliefs you never wrote down.

Stratum is the layer corporations never built.

A living system of record for strategic assumptions, dependencies, and decision-ground-truth — the connective tissue between quarterly planning and what your team actually does on Tuesday.

• Assumption graph — what depends on what
• Drift radar — beliefs going stale before they break you
• Signal feed — evidence that contradicts what you still "know"
• Alignment matrix — where teams secretly disagree
• Board brief — assumption health, not vanity metrics

Clone it. Plug your API key. 60 seconds. Free. Local.

Sound familiar?

• ✅ Strategy deck from January → nobody can list the 5 beliefs it depends on
• ✅ Product ships X, Sales promises Y → same company, different reality
• ✅ Post-mortem: "we assumed churn was about price" → never validated, never logged
• ✅ Board asks "what's our biggest strategic risk?" → you list KPIs, not assumptions
• ✅ You have GRC, OKRs, ERP → no system of record for what must be true to win

Nodded twice? Your house has mess. Stratum is the flashlight.

Quick Start

Prerequisites

Tool	Version	Check
Python	3.10+	python --version
Node.js	18+ (for npm scripts)	node -v

1. Clone & configure

git clone https://github.com/Sunradiance/stratum.git
cd stratum

cp .env.example .env
# Edit .env — add your 3 API keys (see below)

2. Install & run

npm run setup    # installs Python deps
npm run dev      # starts Stratum

Open http://localhost:8791

The 3 APIs

#	Key	What it powers	Get a key
1	LLM_API_KEY	AI analysis, premortems, blind spots, brief enhancement, assumption extraction	Groq (recommended)
2	TAVILY_API_KEY	Live web signal scanning against your assumptions	Tavily
3	SERPER_API_KEY	Supplementary Google search for contradicting evidence	Serper

Minimum to start: LLM_API_KEY alone enables all AI features. Add Tavily + Serper for web signal scanning.

Example .env (Groq + Tavily + Serper)

LLM_API_KEY=gsk_...
LLM_BASE_URL=https://api.groq.com/openai/v1
LLM_MODEL_NAME=qwen/qwen3-32b

TAVILY_API_KEY=tvly-...
SERPER_API_KEY=...

Any OpenAI-compatible LLM works — change LLM_BASE_URL and LLM_MODEL_NAME for OpenAI, Together, DeepSeek, etc.

Features

• Command Center — org assumption health score, drift radar, cascade risk
• Research Thesis — synthesis of enterprise research on the strategy-execution gap
• Strategy Pillars — link bets to the assumptions they stand on
• Assumption Graph — dependency + contradiction visualization
• Signal Feed — contradicting evidence (manual + AI web scan)
• Decision Trace — major calls linked to assumptions
• Premortem Lab — AI-generated failure scenarios
• Alignment Matrix — cross-team belief disagreements
• Board Brief — exportable markdown + AI enhancement

All data is local-first (IndexedDB in your browser). API keys stay on your machine in .env — never sent to a Stratum server.
