A personal CRM for dealmakers — kept alive by your agent

The people who will change your life are already two handshakes away.

Mycelium is the private graph of everyone you know — grown and tended by your AI agent from the notes, calls and meetings you already have. You never fill in a form again. And nothing you know leaves your instance unless you publish it.

$ claude mcp add mycelium https://mycelium.netcraft.works/mcp — that’s the whole integration.

Why every personal CRM died

They all died the same death — and it wasn’t bad design.

It was arithmetic. A personal CRM is worth exactly as much as your discipline of data entry. For two weeks you logged every call. Then a busy Tuesday happened. The graph fell a week behind, then a quarter behind — and a CRM that is a quarter behind is not a tool. It’s a museum of who you used to know.

That era just ended. An LLM agent can maintain the graph from what you already produce: meeting notes, call transcripts, a voice memo recorded in a taxi. Your agent reads them, works out who’s who, files the facts, links the people, keeps the timeline warm — every day, without being asked twice.

The system flips: you stop serving the CRM, and the CRM starts serving you.

Private by design

Your most valuable network is the one you already have.

It didn’t come from a platform and it doesn’t belong on one. Mycelium keeps it in your own instance — a database that exists for you alone. When you do choose to share with a trusted peer, the mechanics are blunt: a peer can only ever see a name, a company, and tags from a fixed vocabulary. Everything else physically cannot leave — what peers search is a separately published copy whose schema has no column for free text.

What a peer can ever see

name        Amara Okonkwo
company     Halide Capital
tags        fintech · investor · seeks-deals

Tags come from an open, closed-set vocabulary (~350 terms). A card is a published copy — you review it before it exists.

What cannot leave — ever

notes       —  no column exists
history     —  no column exists
channels    —  no column exists
deals       —  never federated
opinions    —  yours alone

Not a policy — a schema. Open source, so you can check the schema yourself.

Federation is for a small circle of real trust — not another social network.

How it works

No chat. No forms. Your agent, your voice.

Sign in

Your own instance is provisioned in seconds — a separate database, not a row in someone else’s.

Paste one command

Into Claude Code or Codex. Mycelium becomes a tool your agent carries everywhere — MCP-first, agent-agnostic.

Ask in your own words

“Who do I know in Nairobi fintech who could intro me to a bank CTO?” — and get paths, not lists.

$ claude mcp add --transport http mycelium \
    https://mycelium.netcraft.works/mcp \
    --header "Authorization: Bearer myc_…"

> who can intro me to a payments CTO in Nairobi?
  → Amara Okonkwo → Daniel Kariuki (CTO, payments)

There is no agent inside Mycelium and no chat window. You already have an agent — it has your context, your files, your tools. Mycelium gives it the one thing it lacks: a private, structured memory of your network.

Deal engineering

A deal is a shape of interests. See the whole shape.

For every player, Mycelium tracks four things: what they want, what they can give, what they won’t accept — with hardness — and what constrains them. Including you: you’re a player too.

And the part every pipeline tool ignores: what you don’t know is recorded, not skipped. Every unknown is a first-class entry with a probe to close it. Absence of information is a signal.

Offers climb a ladder — small, reversible moves before big ones. And at night, a reflection pass thinks about your active deals while you sleep: what changed, which unknown matters most now, what the next rung is. It proposes. It never acts without you.

Positions — fundraise, Series A

	You	The fund
WANTS	$3M at sane terms	a wedge into East-Africa fintech
CAN GIVE	board seat	intros to 3 portfolio banks
WON’T	2× liquidation pref (hard)	unknown: their WON’T on exclusivity probe → ask about past co-investments
CONSTRAINTS	runway ends in Q1	fund closes new deals in Nov

Deals never federate. They exist only in your instance — structurally.

Грибница · the mycelium

Underground, the strongest networks are invisible.

A forest looks like separate trees. Underneath, mycelium threads connect the ones that trust each other — nutrients move quietly, root to root. That’s the model: connect your instance to instances of people you actually trust, and search each other’s published cards. “Who does Egor know in Berlin logistics?” becomes a query — not a favor that takes three weeks.

There is no directory, no public graph, no invite-your-whole-address-book growth hack. An invite link is minted for one person and dies in 24 hours. The network grows one trusted handshake at a time — which is why it stays worth querying.

Symmetric honesty

Every query a peer runs on your base is written to a log you can read — terms and time. And every query you run is visible to them. Searching a friend’s network feels like asking out loud in front of them. That’s not a limitation; that’s the point.

in   ← egor       fintech · cto          2 results
out  → egor       logistics · berlin     1 result
in   ← kevin      insurance · nairobi    0 results

Open source & self-host

Don’t trust us. Read the code.

The core is AGPL-3.0. The federation protocol and the sharing vocabulary are Apache-2.0. The claim that free text cannot reach a peer isn’t marketing — it’s a schema constraint you can go and read.

And an honest line most hosted products won’t say: hosted Mycelium is not end-to-end encrypted — server-side search and analysis need plaintext. If your network is your life’s work, run the open-source version on your own machine. It federates with hosted instances all the same. For everyone else, hosted is the convenient default — and deleting your account really drops the database.

Questions, answered straight

Is there a chat inside Mycelium?+

No. You talk to your own agent (Claude Code, Codex — anything that speaks MCP with a bearer key). A built-in chat would be a second, worse agent.

Can I add or edit contacts in the web UI?+

No. The cabinet is a read-only preview of your data plus account and consent controls. All writes go through your agent — that’s the design, not a gap.

What exactly can peers see?+

Only cards you explicitly published: name, organization, and tags from a closed vocabulary. Notes, contact details, history and your comments have no column in the shared schema — they cannot leave.

Are my deals visible to anyone?+

Never. Deals are structurally non-shareable; they exist only inside your instance, and nightly reflection runs there too.

What happens when I delete my account?+

Your entire database is dropped — contacts, deals, published cards, keys — and sessions are invalidated. Real deletion, not a flag. Export first via your agent if you want a copy.

Can I self-host?+

Yes. The core is AGPL and self-hosting is the recommended path for the most sensitive networks. Self-hosted instances federate with hosted ones over the same open protocol.
