fein for private equity
Self-hosted · open source · live in 14 days

Every intermediary who sends you deals. Ranked, owned, and current.

An intermediary is a banker, a broker, an accountant, or a lawyer who brings you deals. Your firm has thousands of them. Their record sits in ten thousand emails. fein reads those emails. fein resolves each intermediary into one record. fein scores the relationship from real signal. fein names the person at your firm who owns it. You ask a question in Claude, ChatGPT, or Cursor. Each answer arrives with its source document attached.

The problem

Your edge is proprietary deal flow. Nobody can see it.

  • Your coverage is a guess. Your firm has thousands of intermediary relationships. The CRM shows one picture. The inbox shows a different one. Nobody knows which picture is correct.
  • Relationships go quiet in silence. An intermediary sends you three deals. Then eleven months pass with no contact. You learn this when the next deal goes to a competitor.
  • Ownership leaves when people leave. A partner holds a relationship for six years. The partner moves to another firm. What the partner knew was never written down.
  • Deal history is not searchable. A company you passed on in 2023 returns at a lower multiple. The memo, the reason, and the intermediary sit in three systems and one person's memory.

What you get

Four questions your deal team asks each week.

fein answers each question from the record your firm already makes. It answers in seconds. It shows the source document for each answer.

01

Your coverage map

fein lists every intermediary who sends you deals. It scores each relationship from real signal. The signals are meetings, replies, and shared documents. fein does not use a field that somebody filled in. Each row names the person at your firm who owns the relationship.

02

The relationships that go quiet

fein learns the rhythm of each relationship from your history. Then it flags each relationship that drifts away from that rhythm. It shows the last contact, the deals that intermediary sent, and the colleague who must make the call. fein uses dates and intervals. It does not guess.

03

Each deal, and where it came from

fein shows which intermediary sent the deal and when. It shows what your team said. It shows the exact reason you passed. Each line points to the email or the document that it came from. You ask once, in plain language.

04

The warm path in

fein finds the shortest real path to a management team, a seller, an operator, or an LP. It weighs each step against how well your firm knows that person. Then it names the best colleague to make the introduction.

How it works

Nobody enters data. The graph builds itself.

01

fein reads what your team already writes

It reads your email, calendar, Drive, LinkedIn, and CRM. It reads them continuously. It reads years of history on the first pass. Your deal team logs nothing and changes nothing.

02

fein resolves the record into one identity per person

It joins every duplicate copy of a contact into one record. It scores each relationship from real signal, not from a language model guess. When a fact stops being true, fein retires it. A retired fact keeps the dates it was true between, so your history stays queryable.

03

fein answers where your team already works

It serves one MCP endpoint. You ask in Claude, ChatGPT, Gemini, or Cursor. You get the same answer each time. Each answer carries its source document. Your agents read a deterministic map. They do not scrape files and guess.

Your CRM stays

It sits on top of the systems you run today.

fein works with DealCloud, Affinity, Salesforce, and Attio. It reads your CRM and everything around it. It resolves the whole picture into one graph. It replaces no system. It migrates no data. It asks your team for no new data entry. If your CRM is out of date, fein is still current, because fein reads the record your team makes anyway.

Security

Your data never leaves your servers.

fein reads your inbox, your calendar, and your CRM to do its work. It does that work on your own infrastructure. You can read every line of the code before you run it.

  • It is always self-hostedfein runs in your environment. It sends nothing to us.
  • It is open source, end to endEvery line that touches your data is public. Audit the code before you run it.
  • It is private by personEach person's sensitive sources stay in their own layer. fein enforces this inside every query.
  • It writes down every changefein logs each ingest, each merge, and each decision with the person or agent that made it.
  • One token gates every surfaceThe dashboard, the API, and the agent endpoint sit behind the same gate.
  • Nothing phones homefein sends no telemetry and no analytics. We operate no control plane for you to trust.

Pricing

We price on fund size. We never price per seat.

An analyst who keeps this record current costs six figures each year. The graph then lives in that one person's head. fein costs less than one month of that analyst. Every person at your firm can query it.

Fund size
Under $250M$1,000 / month
$250M to $1B$2,500 / month
$1B to $5B$4,000 / month

Clone it and run it yourself$0 / forever

You also pay $5,000 once. That fee builds fein into your stack. It is live in 14 days. An annual plan, paid in advance, costs 15% less. The code is MIT licensed, so you can always run it yourself for nothing. The fee pays for the engineer who builds it into your environment. The engineer also keeps each connector working through every API change.

We take five firms this quarter.

  • It is live in 14 days. The date is a commitment, not an estimate. Your part is two short calls.
  • You have thirty days to decide. If fein is not useful to your deal team, we refund everything. This includes the build fee.
  • Your price is locked at the band you join on. It stays locked for as long as you are a customer, through every fund you raise.

Questions

What deal teams ask first.

We already have DealCloud. Why do we need this?

A CRM is a database that your team fills in by hand. It is only as current as the last person who updated it. fein is not a CRM and it replaces nothing. It reads your CRM and everything around it. It resolves the whole picture into one graph. It keeps that graph current, and nobody touches a field.

fein answers questions that a CRM cannot. It measures the strength of a relationship from real behaviour. It flags the intermediaries who go quiet. It shows why you passed on a deal three years ago, and it shows the document that says so.

Where does our data go?

Your data goes nowhere. fein runs on your infrastructure. It sends nothing to us. It has no telemetry. We operate no control plane in the path. Every line of code that touches your data is public. You can read it before you run anything.

What must we do?

You join two short calls. On the first call we connect your email, calendar, Drive, LinkedIn, and CRM. We do all of the work between the calls. On the second call, fourteen days later, you check the answers against what you know. Then fein goes live.

How far back does it read?

It reads as far back as your mail retention allows. Most firms give us years of history on the first pass. That is the point. On day fourteen fein answers like a colleague who has been at your firm the whole time.

Can we run it ourselves?

Yes. fein is MIT licensed and the repository is public. The code we deploy for clients is the code you clone. The fee pays for the build and the upkeep. Your engineers then build on top of the graph instead of maintaining connectors.

What happens if we cancel?

Nothing stops. fein runs on your servers. The graph, the connectors, and every answer stay where they are. They keep working.

Get started

Give us twenty minutes. We will show you your own graph.

Tell us the name of your firm. We come to the call with what we can already see in public deal data. That is the intermediaries who send you deals, and the ones who have gone quiet. If it is not interesting, we have taken twenty minutes of your time and none of your money.

You can also write to sales@fein.vc.

We reply the same day. There is no sequence and no newsletter.

Thank you. We have your details. We will send you times today.
