# fein

> fein is an open source memory layer for venture capital teams: a live, permissioned relationship graph built from the team's inbox, calendar, and CRM, answering inside AI tools like Claude, ChatGPT, and Cursor over MCP: warm intros, meeting prep, and deal history, every fact linked to its source. Live in 14 days, self-hosted on the team's own infrastructure. Pricing: $5,000 one-time build + $1,000 per month, or free if the team runs it themselves (open source).

## What fein does
- Find the warmest introduction to any founder, LP, or operator, and who should make it.
- Prepare for meetings: who is in the room, how you know them, what you last discussed.
- Recall every company the team has seen, and exactly why it passed.
- Flag relationships going cold, judged by each contact's own cadence.

## How it works
- fein reads your existing systems (email, calendar, Google Drive, LinkedIn, CRMs like Attio and Affinity) and builds a relationship graph automatically, with no CRM to keep updated by hand.
- It serves answers over a single MCP endpoint, so you query it from Claude, ChatGPT, Gemini, Cursor, or any MCP client.
- Delivered forward-deployed: live in 14 days, two short calls from your team.

## Pricing
- $5,000 one-time build.
- $1,000 per month maintenance (connectors kept working, graph kept current, new answers built on request).
- About $17,000 in the first year.
- Month to month, no lock-in: cancel and the self-hosted software and graph remain yours.

## Security and data
- Self-hosted in the team's own environment; data never leaves it.
- Open source and auditable end to end: teams can clone the repo and run fein themselves; the paid offer is setup and upkeep.
- Per-person access, enforced on every query.
- Every query logged, tied to a person.
