💡Phase 1: Idea Phase→

Your next move. Always clear.

One workspace for every venture you're building — project Brain, phase machine, credentials vault, and an MCP server that gives your AI tools the full picture.

Phase Machine

From idea to institutional in one workspace

Phase 1

Validate before you commit

Capture the idea. Map kill assumptions. Run reality checks. Gate 1 opens only when every kill assumption is validated with real evidence — no guesswork, no AI-inflated numbers.

Gate 1 predicates
Kill assumptions validated
Risk corridor defined
First paid signal logged
Gate Evaluation

No AI produces the numbers that open a gate

Every gate predicate is machine-checkable from real data you enter — runway from actual financial snapshots, demand from verified paid signals, legal from entity records. You can't talk your way through a gate.

📊
Real data only
Gates read financial snapshots, assumption records, and entity verification — never model output.
🔒
Server-side evaluation
Gate logic runs on the server. Your client can't override the predicate.
📜
Full audit trail
Every gate event is timestamped and logged. The predicate state at advance time is preserved.
Brain MCP

Your AI tools work on your project

One key per workspace plugs Claude Desktop, Cursor, and Codex into the same structured Brain. They read your strategy, ICP, tech stack, and decisions — and write back updates as you iterate.

Project Brain

Structured knowledge graph per venture — strategy, ICP, tech stack, decisions. Versioned with full rollback.

🔌

Brain MCP

Claude Desktop, Cursor, Codex — all read and write your Brain via one workspace API key. No more copy-pasting context.

🔐

Credentials Vault

API keys, accounts, and tokens encrypted via Supabase Vault. Per-project, never exposed in the client bundle.

⚡

BYOK AI

Bring your Anthropic or OpenAI key. Brain Fill writes every section and answers grounded questions. Your bill, not ours.

📋

Decision Log

Every decision recorded with reasoning, alternatives, and outcome. Brain surfaces past mistakes before you repeat them.

🤝

Workspace + Team

Invite cofounders and contractors with role-based access. Per-workspace billing, AI keys, and audit log.

Multi-venture

One workspace. Many ventures. Each at its own phase.

You're a CEO on one project and testing a new idea on another — same workspace, different phase machines. Switch projects and the whole OS adapts: phase indicators, gate status, Brain context, AI keys.
