KXCO Meridian

The private-capital deal network.

Originate, negotiate and settle private-capital deals, with counterparties you can actually verify.

Meridian is where family offices and institutions run the whole deal: a live deal board, NDA-gated data rooms, offers and commitments, diligence, quantum-safe signing and settlement. Every member is identified by their KXCO ID, and every state change is signed to a tamper-evident audit trail.

The Problem

Private deals run on trust you can't check.

Private-capital deals still move on email threads, shared drives and PDFs, introductions taken on faith, NDAs and term sheets scattered across inboxes, and no single record of who saw what, agreed to what, and when. The counterparty on the other side is whoever the introduction said they were.

When it matters most, a dispute, an audit, a regulator's question years later, the proof is a folder of files that anyone could have altered, signed with cryptography that a quantum computer is expected to break. A signature valid today can be forged retroactively, and adversaries are archiving signed documents now to do exactly that.

Meridian replaces the folder with a network: verified members, gated rooms, signed actions, and one audit trail everyone can rely on.

Why It Matters

A deal network for the age of AI and quantum.

Verifiable
Counterparties, not aliases
Every member is admitted through KYC and identified by a single KXCO ID that carries across every deal, room and signature. No anonymous introductions, you always know who is on the other side, and so does the record.
Quantum
Proof that outlives the algorithm
Signatures, NDAs and audit entries all use ML-DSA-65 (NIST FIPS 204), so they stay valid after the deadlines that retire today's cryptography. Every state change is anchored on Armature L1, a permanent record any counterparty, auditor or court can confirm.
Accountable
One trail, nothing hidden
Access a room, sign an NDA, place an offer, execute a document, record a capital call, each is a signed, timestamped, hash-chained event. Nothing can be altered or reordered without detection, and every party sees the same history.
How It Works

The whole deal, on one network.

From first look to closed position, every step verified, signed and on record.

01
Originate on the deal board
Issuers publish offerings, equity, debt, convertibles, private placements and more. Reusable deal templates instantiate a room index, so the second raise is not built from scratch. Investors browse the board, register mandates, keep watchlists, and get matched to deals that fit their remit. An offering can carry a public proposal page, and every member has a page of their own at meridian.kxco.ai/p/their-handle.
02
Open the data room, on your approval
Readers sign a quantum-attested confidentiality undertaking, sealed with ML-DSA-65 and bound to the hash of the document shown. Signing raises a request rather than opening the room: you are told somebody is waiting, and you choose the level they get. Links can be locked to the people you sent them to, and every reader's copy is watermarked to them. A data room is an object in its own right rather than a tab on a deal: it belongs to the person who created it, and it can stand alone or be attached to an offering. Per document you choose view-only, downloadable through a recorded notice, or named readers only. Folders arrange documents, they never grant access. Documents carry version chains with material-change reports, a redaction workflow, and screen-capture detection.
03
Negotiate: offers, commitments, diligence and Q&A
Investors place offers that become commitments; both sides run diligence and a threaded Q&A against the deal, every exchange attributed to a verified member and timestamped. Issuer and investor diligence each have their own checklists, memos and information requests, and a closing checklist tracks the conditions still outstanding.
04
Execute with quantum-safe signatures
Term sheets and closing documents are signed in-network with ML-DSA-65 over the document hash, legally binding, independently verifiable, and tied to the signer's credential.
05
Settle and track the position
Settlement instructions and issuer-entered deposit details close the deal. Capital calls carry per-investor obligations and payments; distributions run through a configured waterfall to per-investor allocations; cap table entries and valuations flow into portfolio and capital accounts with MOIC and XIRR. KXCO never holds assets or keys.
06
Run the operation around it
The record is only useful if the back office runs on it. Bank accounts are stored encrypted and reconciled against statement lines; FX rates and fee schedules price what is owed; invoices, payment requests and annual membership terms bill it; referrals credit whoever brought the business. Entities and organisations carry their own issuing names, so an advisor listing for a client is never confused with the client. Reports and exports come out as CSV, Excel or PDF. Accounts are protected by multi-factor authentication with recovery codes, and anything that needs a human decision lands in an approval queue with the evidence attached.
The Trust Layer

The trust layer, applied to private capital.

Identity, signing, data rooms and verification, native to Meridian, purpose-built for how private-capital deals actually run.

Identity
KYC-gated membership, one KXCO ID
Every member is admitted through KYC and carries a single ML-DSA-65 identity across the network, the root every signature, room entry and audit entry traces back to.
Enter Meridian →
Data Rooms
Gated rooms with a provable trail
Per document: view-only, downloadable through a recorded notice, or restricted to the people named on it. A signature raises a request and the issuer decides who enters; every open is timestamped and the trail is anchored on-chain.
Enter Meridian →
Signatures
Quantum-secure e-signatures
ML-DSA-65 (FIPS 204) signatures on every document, with on-chain attestation and public verification, legally binding and built to outlast today's cryptography.
Enter Meridian →
Record
Anchored on Armature L1
Every seal and credential event is anchored on a permanent, independently verifiable ledger, confirmable with no KXCO account and no dependency on KXCO continuing to operate.
