“Have we seen this company before?”
The 2023 memo, the exact reason you passed, the intermediary who brought it, and what has changed since. One question, answered from your own record instead of a partner’s memory.
Every IC memo, every pass and the reason for it, every banker relationship, every management team your partners have met. It sits in inboxes, drives, and people’s heads. fein reads it all into one private, searchable memory for your whole firm. On your servers. Nothing leaves the building.
Northwind Capital. They asked for more AI infrastructure exposure at the March review12 Mar 2026, and Halo Compute cleared the design partner objection in June2 Jun 2026. The warmest path in is Dev Raman, who forwarded the deck in 20248 Nov 2024. This changed four hours ago: Dev offered that introduction again in #dealflowToday 14:16, so the path is open today and not two years old.
Four things. You saw a $4M seed8 Nov 2024, and it is a $30M Series A now with six design partners live2 Jun 2026. They hired a VP Engineering out of Databricks3 Jun 2025, and Marcus moved it to IC in July14 Jul 2026.
Dev Raman made the introduction and still co-invests8 Nov 2024. Marcus Feld has owned the conversation since, and answered it again last week#dealflow. Nobody here has met the founders since the coffee in 202421 Nov 2024.
It reads and answers in the tools you already use
Most firms bolted a chatbot onto systems that hold almost nothing. The model knows everything about the world and nothing about the firm. So it answers like the internet, not like a partner.
We spent years building the CRMs and data workflows inside 50+ private capital firms. The same pattern everywhere: the firm’s real intelligence never lands in any system. It lives in heads and leaves in exits. When AI arrived, it had nothing to read. So we built the layer we kept wishing existed: one graph of everything the firm already knows, on the firm’s own servers, readable by every partner and every AI tool the firm runs.

The only input your competitors cannot rent is the context your firm has already accumulated. And the questions investing actually runs on, have we seen this before, who knows this space, why did we pass, are answerable only from it. Once that is clear, three decisions get simple.
fein answers each one in seconds, in Claude, ChatGPT, or Cursor, from the record your firm already makes. Each answer carries the document it came from.
The 2023 memo, the exact reason you passed, the intermediary who brought it, and what has changed since. One question, answered from your own record instead of a partner’s memory.
Every intermediary who sends you deals, scored from meetings, replies, and shared documents, with the partner who owns each relationship named on the row.
fein learns the rhythm of each relationship from your history and flags the ones drifting from it, before the next deal goes to a competitor.
The shortest real route to a management team, a seller, an operator, or an LP, weighed by how well your firm knows each person on it. The answer names the colleague who should make the call.
Deal flow is the most sensitive record your firm holds. fein reads it inside your own environment, and sends nothing to us. You can read every line of the code before you run any of it.
fein runs in your environment. It sends nothing to us.
Every line that touches your data is public. Audit it before you run it.
fein logs each ingest, each merge, and each decision with the person or agent that made it. The rest, from per-person privacy to the single token gate, is on the security page.
fein is Apache 2.0 licensed and self-hosted. Your engineers can clone it and run it for nothing, forever. What a deal team buys instead is the build: a forward-deployed engineer who connects every source, reads years of history into the graph, and hands your partners a working memory they can question.
The whole platform on your own servers. No trial, no seat count, no call with us.
A forward-deployed engineer builds fein into your firm and stays on it.
The monthly plan covers hosting support, connectors kept working through every upstream API change, and new sources as your stack changes. Never per seat: every person at your firm can query the graph, and so can every agent they run.
The chat layer, yes, in an afternoon. The part that takes the fortnight is underneath: connecting every source, resolving a decade of duplicate people and firms into one record each, and keeping it all current through every upstream API change. That layer is the product. It is also open source, so building it yourself and running fein are the same road; we have just walked it 50 firms’ worth of times.
Most firms we deploy for have none. That is what the forward-deployed engineer is for: your part of the fortnight is two short calls, one on day 1 to connect your systems, one on day 14 to check the answers before it goes live. Nobody at your firm enters data, then or ever.
Nowhere. fein runs on your infrastructure and sends nothing to us: no telemetry, no control plane of ours in the path. Every line of code that touches your data is public, so you can read it before you run anything.
The engineer works inside your environment, on access your IT grants and can revoke at any time. Our people are bound by confidentiality, and access is limited to those who need it to support the service. It ends when the build ends, unless you ask us to keep the connectors supported.
One thing we will not overstate: fein does not today keep a tamper-proof audit trail of administrative access. Your own logging is the record that counts. The graph also sits unencrypted above the volume, so anyone with host access can read it. That is true of your other systems too, and it is why the host is yours.
fein replaces nothing. A CRM is a database your team fills in by hand; fein reads it, along with everything around it, and resolves the whole picture into one context graph that stays current on its own.
It also answers what a CRM cannot: how strong a relationship really is, which intermediaries have gone quiet, and why you passed on a deal 3 years ago.
Nothing stops. fein runs on your servers, so the graph, the connectors, and every answer stay where they are and keep working.
Come with one question your firm cannot currently answer without a partner’s memory or an analyst’s afternoon. On the call we show you, on your own stack, how fein would answer it. If it is not interesting, you have lost 20 minutes.
