## About

Mandel is the AI Coordination Layer for Supply Chain. It chases suppliers, gathers complete quotes, resolves order changes, pursues invoice corrections and credits, and updates the ERP. The work runs across email, documents, portals, EDI, and existing business systems, within agreed approvals. Each case keeps the evidence, actions, decisions, and outcome together. Teams can start with a historical review of supplier correspondence and order records; the review sends no messages and changes no ERP records. Detected exposure is kept separate from verified recovery. Founded in 2023 by Nick Gospodinov. Backed by Y Combinator (S23), Category Ventures, Ritual Capital, and e2vc. Based in San Francisco, CA.

- Over $1B+ in material spend processed
- SOC 2 Type II compliant
- Works across email, documents, portals, EDI, and ERP

## Features

### Supplier work carried through
Mandel gathers complete quotes, follows up on confirmations, resolves discrepancies, and pursues claims. The result and supporting evidence stay with the case.

### Cross-system execution
Mandel gathers the evidence a job needs across email, documents, portals, EDI, and ERP, then takes the next action inside the authority you grant.

### ERP write-back
Mandel reconciles contradictory records and writes the verified outcome back to the source-to-pay or ERP system so the operational record stays current.

### Decision-ready escalation
Mandel acts autonomously where authorised. When judgement is required, it brings the investigation, evidence, and proposed action rather than another raw alert.

### Historical replay
Review past supplier messages and orders to identify missed changes, unresolved follow-ups, and possible credits. Proposed actions are not live actions; potential exposure is not recovered money.
