Delegate procurement to AI agents.
With Lemma, you can hand routine ordering to an AI agent as a delegation scoped by spend ceiling, budget category, and approved vendors: inside that scope the agent orders autonomously, and outside it the request simply stops — so you hand over scope, not the whole decision.
Three voices from the front line.
- Procurement / purchasing
“We want to automate routine ordering, but can't hand vendor selection wholesale to the AI”
- Accounting
“We want budget control on orders enforced in real time”
- Audit
“We want the authority behind an AI's order to be verifiable after the fact”
Hand over the source, or just the facts?
Nothing changes on the floor. Everything changes for the receiver.
① Your team just saves, as always.
- The usual step
- Fill in the record and save
- On save
- A proof is attached (API, behind the scenes)
- The document itself
- never sent
② They just open a link.
- Proven fact
- within scope, the AI may place the order
- ordering authority, budget and supplier data
- not shown
- Login / keys
- not needed
- The document stays private — the record itself is never sent or disclosed.
- Independent verification — the receiver just opens a link. No account, no keys.
- Edits are detected — even a one-character edit fails verification.
The procurement team issues a signed delegation with a spend ceiling, approved vendors, categories and validity. Before confirming an order, the agent verifies it stays within scope at runtime — ordering autonomously inside it and stopping outside it. Without disclosing supplier data or budgets, the fact "ordered within an authorized delegation" can be independently verified.

Only work that needs all three at once — pass without exposing, independent verification, tamper-evidence — is Lemma's domain.
| Method | Pass without exposing | Independent verification | Tamper-evident | What happens |
|---|---|---|---|---|
| Access control / permissions | △ | ✗ | ✗ | “Someone inside could have edited it” remains possible |
| Masking / redacted copies | △ | ✗ | ✗ | Redaction work grows; the original is still unproven |
| Encrypt and store / send | ✓ | ✗ | ✗ | To verify, the receiver needs it disclosed after all |
| Lemma (ZK proof)the only one with all 3 | ✓ | ✓ | ✓ | The receiver just opens a link |
