Become a Founding Steward
A one-time $79 reserves your namespace and secures your first-in-line claim to author your own laws. Provision your Day 1 Law before anyone else can take the name.
Build intuitively · Design absolutely
Reserves your namespace and secures your first-in-line claim to author your own laws. No subscription yet.
Your tier subscription begins at general availability; the $79 comes off your first invoice. No monthly charge before then.
Shadow until you sign your own genesis charter — we never mint your key. authority_effect = 0.
One plug for every agent. The Substrate speaks MCP — point any agent that already speaks the protocol at it, and every consequential action it proposes is admitted or refused before it runs. Live today over REST and MCP — point any MCP client at /mcp.
Want to see it first? The free demo runs the example across all four tools on a shared demo namespace — no card, no signup.
See how it works →Your tier is your rate at GA — chosen now, billed later. At general availability each tier is a monthly plan with included seats and governed actions, then metered overage (Sovereign is flat). Today you pay only the one-time $79.
By reserving you agree to our Terms, Privacy, and Refund policy. Your chosen tier is locked in at reserve — the one-time $79 is credited to it.
Your namespace is your org's admission space — locked at checkout like a domain: one name, one owner (e.g. acme-refunds, northwind-payouts). Lowercase letters, digits, hyphens; 3–64 chars. First-paid-wins: a taken name is refused, never silently remapped, and only your claim token can charter it at Day-1.
Every tier self-serve, even Sovereign — no sales calls, no contracts, no waiting. All features on every tier; you pay for scale, not features. Checkout is by Stripe; we hold only your email, tier, and session, and nothing binds authority yet (authority_effect = 0).
