Your IP never
leaves Germany.
Capability flows in; your data flows out to no one. Sovereignty at Amp-Hour is not a slogan — it is the direction data is allowed to travel, enforced by the entity, the systems and the contract.
Every cell foundry says “sovereign.” We can draw ours: capability and IP come in, a finished cell goes out, and your data never crosses back — by architecture, not assurance.
- Entity
- CELLOVATE GmbH — German management and jurisdiction
- Location
- Bohr 12, 52072 Aachen, Germany
- Data
- One-way in; your IP and program data never leave
- Supply
- From 100% local to partially local, tuned to your program
One-way is a direction, not a promise.
Most sovereignty claims describe intent. Ours describes flow. Capability, tooling and your own chemistry enter the entity; a qualified cell leaves it. What does not leave — ever — is your intellectual property, your program data and your production records. That boundary is built into how the systems are wired, not bolted on as a policy line.
The practical effect is simple: the people who design with us keep everything that made the design theirs. We provide the sovereign capacity to produce it — nothing more, and nothing that flows the wrong way.
- German management, facilities and jurisdiction
- Capability in, cell out — data one-way
- Your chemistry, form factor and IP retained
- Supply chain tuned from 100% to partially local
Built to hold when the commercial pressure comes.
A promise is only as sovereign as the day nobody tests it. We separate branding, systems and data infrastructure from any affiliate, and we enforce it two ways at once — contractually, and in the physical architecture of the systems — so the boundary survives commercial pressure, ownership changes and the ordinary gravity of a group.
Your competitor may share a hallway with someone we work with. They will never be in your data.
Capability comes in. Your data never leaves.
