Contact & early access
Join the waitlist, or talk to us about design partnerships, integrations and security reviews. One form, no dark patterns, and we never re-ask for something you already told us.

Other paths
Design partnerships
Named partners get early builds and a working session on the invariants your product depends on — governance, isolation, audit evidence.
Integrations & SI enquiries
Mapping legacy estates onto one ledger, batch or streaming; every load leaves a receipt.
Planning-vendor partnerships
Consume actuals and scenarios from one ledger with an explicit composition boundary.
Security reports
Coordinated disclosure: see security.txt for the reporting channel, or review the security page.
What to expect
What does “design partner” mean concretely?
A named collaboration: you get early builds and direct engineering contact; we get structured feedback on the invariants and interfaces you need. No fees and no commercial promises — pricing instruments are not published yet.
When does access open?
Waitlist invitations go out ahead of the developer preview; design partners are sequenced first. You will not get a marketing drip — access updates and the changelog digest only.
Can our security team review the deployment?
Yes. The security posture, deployment classes and the attestation roadmap (SOC 2 Type II targeted inside PH-2) are documented for questionnaire review; write to us and we will route it properly.
