The substrate produces the handoff.

You need humans for legal sign-off, regulatory strategy, and your internal risk committee. We don't replace any of those. What we replace is the consultant who'd otherwise generate the L12 chain + audit bundle + framework mapping by hand at €195k per system. The substrate emits that automatically. Your lawyer reads the output, your DPO files it. If you want one human call before your first DPA meeting, the €5k add-on covers that.

Because the substrate's own outputs do 90% of what the service was charging for. The €195k paid for two engineers' time over 90 days — €117k of that was their salaries, the rest was margin. We removed the engineers. The substrate writes the same audit bundle, generates the same framework mapping, produces the same notified-body-readable packet. You don't need our engineers between you and the substrate's outputs.

Seven frameworks shipped: GDPR, AI Act Annex III/IV, PSD3, DORA, NIS 2, MDR, HIPAA. Each template covers the article-by-article mapping the notified body needs. If your jurisdiction's regulator wants a specific format we don't have, you can extend the template yourself (it's TypeScript) or commission a custom one (€15k one-time, becomes part of the substrate for everyone). 99% of regulated-EU buyers fit one of the seven shipped frameworks.

That's the most common case, and it's where the optional €5k DPA-session add-on earns its keep. We've designed the chain so it maps onto familiar regulatory shapes — GDPR Art. 30 records, DORA Art. 17 audit trails, AI Act Annex IV documentation. Regulators don't need new mental models; they need familiar shapes filled with verifiable evidence. The optional add-on covers the first regulator session if you want a substrate engineer in the room.

Apache 2.0 substrate (kernel + generators + SDK + verifier). Your spec is yours. Your chain is yours. Your integration code is yours. If you cancel Enterprise, you keep everything. The verifier is 150 lines of plain JS; you can audit it in an afternoon. Self-hosting is supported on the same tier (Enterprise on-prem) — you can run the entire stack inside your VPC.

Two things, both partnership structures: (1) Frontier-model OEM — if you're Anthropic / OpenAI / Mistral / Cohere wanting to bake the substrate into your API surface, that's a revenue-share or royalty deal that doesn't fit a fixed price. (2) AI-vendor channel — if you're a LangChain / observability / orchestration vendor wanting to resell substrate-emitted audit chains to your enterprise customers, that's a reseller deal at €80k+/yr per integration. Both are rare, both are sales-led, both are the genuine exceptions. For everything else: Stripe checkout.
