How it works

Type your idea

One sentence. The agent writes an ISL blueprint — a verifiable spec of your app, not a hopeful guess.

It ships only if it's proven

Eight blocking proofs run against a real Postgres. The verdict is SHIP or NO_SHIP — never a fake green.

Launch a real business

Domain, Stripe, legal, emails and a live cockpit — the whole company stands up on day one.

From idea to income — proven

Proven full-stack app

Real code, verified it works before it ships — not a demo that breaks.

Go-to-market plan

Your entire GTM drawn + a readable plan, grounded in your app.

Brand & launch kit

Name, voice, copy, social, emails, pitch — one coherent identity.

Legal, auto-published

Terms, Privacy, Cookie & Refund — approve, and they land on your site.

Real payments

Your pricing becomes live Stripe products + a checkout that collects.

Your domain

Pick it, connect the DNS, attach it to your deployment.

Launch execution

Waitlist, scheduled emails, social — actually send it.

Launch HQ cockpit

Real analytics, revenue & errors in one place. Run many businesses.

Their scanner checks that an RLS policy exists. We run the attack and prove it holds.

Every build is verified before it ships and stays verified through every change. When a proof can't run, it says can't verify — never a fake green.

What blocks the ship

Tenant isolation

Your DDL is applied to a real Postgres, then a cross-tenant attack matrix runs as a non-owner under FORCE RLS. Tenant B reads zero of tenant A's rows — or it doesn't ship.

Role matrix

Every role × read/write/delete × entity is replayed live. Observed access must match the declared permissions exactly.

Cross-entity invariants

Rollups like order.total = sum(items) are maintained by trigger — then adversarially tampered to prove they self-correct, not just seed correctly.

State-machine liveness

Every status flow is graph-checked: no stuck dead-ends, no unreachable states. A pure proof, no infra needed.

Safe migrations

Schema changes apply to seeded data, then RLS and invariants are re-proven against it. No silent data loss between versions.

Checkout integrity

Charges are recomputed server-side from owner-scoped rows. The request carries ids and quantities — never a price the client could tamper with.

Locked-down surface

Every API route carries an auth guard or a declared public opt-out, and no hardcoded secret survives the firewall scan.

Contract equivalence

The emitted typed SDK and OpenAPI are proven to match the real /api routes — divergence is NO_SHIP, not a runtime surprise.
