# Services & Retainers

Three tiers. Every engagement starts with a 30-minute scoping call and a fixed one-page
plan. We bill per engagement or per month — never per hour. Pricing is scoped to the
work on that call: [book a call](https://book.eigenhitchens.com/eigen/intro-call).

## Fixed engagements (two-week pilots)

| Engagement | Pricing | Days | Deliverable |
|---|---|---|---|
| **Sovereign Auth Pilot** | Priced on the call | 10 | Passkey-based identity on your infra, with Auth0/Clerk migration plan |
| **On-Prem AI Co-Pilot** | Priced on the call | 14 | Private LLM with HDC codebook, fine-tune, internal chat UI |
| **Mesh Comms Pilot** | Priced on the call | 14 | Field-deployment WebRTC + LoRa peer-to-peer |
