Two prices, and one of them is zero.
The software is Apache 2.0 licensed. Running it costs nothing and always will. What you can buy is the engineer who builds it into your stack, and the upkeep that keeps it running afterwards.
Self-hosted
The whole platform on your own servers. No trial, no seat count, no call with us.

- →Every feature. There is no paid tier of the software and no feature held back to make one.
- →The context graph, and the memory that keeps it current.
- →The MCP endpoint. Claude, ChatGPT and Cursor query the same graph.
- →The audit trail on every ingest and every merge.
- →The connectors that are built today. You write the ones that are not.
- →Your engineers do the setup, the credentials, and the backfill.
- →Community support through GitHub issues.
Managed setup
A forward-deployed engineer builds fein into your stack and stays on it. Two short calls from you.
$5,000once, then from $1,000 a month
- →Live in 14 days. The date is a commitment, not an estimate.
- →Connectors built for your stack, including the ones nobody has written yet.
- →Every source connected, duplicate people resolved, full history read back.
- →Connectors kept working through every upstream API change.
- →New answers built on request as your team asks new questions.
We price on fund size. We never price per seat.
An analyst who keeps this record current costs six figures a year, and the graph then lives in that one person's head. fein costs less than one month of that analyst, and every person at the firm can query it. Adding people never changes the price.
| Under $250M | $1,000 / month |
| $250M to $1B | $2,500 / month |
| $1B to $5B | $4,000 / month |
| Over $5B | Talk to us |
| Clone it and run it yourself | $0 / forever |
The managed path also carries $5,000 once, which is the build: an engineer connects every source, resolves your duplicates, reads your history back, and hands you a working graph on day 14. An annual plan, paid in advance, costs 15% less. It is month to month otherwise, with no lock-in.
What the monthly fee actually buys.
- →The connectors stay alive. Gmail, LinkedIn, Attio and the rest change their APIs without warning. Keeping thirty integrations working is the recurring work, and it is most of what you are paying for.
- →New answers on request. When your team starts asking a question fein does not answer yet, we build it.
- →Your price is locked at the band you join on, for as long as you are a customer, through every fund you raise.
- →Thirty days to decide. If fein is not useful to your team we refund everything, the build fee included.
What firms ask about the money.
If the software is free, what am I paying for?
Time, and the engineer who spends it. fein is a graph built out of thirty different systems, each with its own authentication, its own rate limits and its own idea of what a person is. Getting that running against your real data, and then reading years of history back through it without creating four copies of every contact, is the work. Firms that do it themselves generally spend a few months on it. We do it in fourteen days because we have done it before.
You are not buying access. The binary is the same one on GitHub, and nothing in it is gated.
What happens if we stop paying?
fein keeps running. It is on your servers, under a licence that does not expire, and the graph is in your own database. Nothing phones home and there is no control plane of ours that can switch it off.
What stops is the upkeep: when a connector breaks against an upstream API change, fixing it becomes your job. That is the honest description of the trade.
Is it per seat?
No, and it never will be. The price is set by fund size and nothing else. Every person at the firm can query the graph, and so can every agent they run. A memory layer that charges by the head is a memory layer people route around.
We are a small fund. Is the build fee negotiable?
The build fee is the same for everyone because the work is the same for everyone. If it is genuinely out of reach, run it yourself: that path is free, it is the same software, and the setup guide is public. Come back to us when the maintenance stops being a good use of your engineer.
Still deciding which column you are in?
Twenty minutes on a call. We will look at your stack and tell you honestly whether this is a fortnight of our time or an afternoon of yours.
