The operating system for your fund
Nyx connects your exchanges, wallets, and brokers, runs a real double-entry ledger alongside your fund admin, strikes NAV, accrues fees, watches risk, and writes the LP report — automatically, every month, from your real positions.

Manual P&L tracking at scale is duct tape over a gas leak. One formula error, one missing row, one stale price feed — your AUM is fiction.
Monthly reports take hours you don't have and money you shouldn't spend. Then the emails start. Then the Zooms. Then the redemptions.
A 20% drawdown doesn't wait for you to open your laptop. By the time you notice, the LP relationship is already damaged.

DATA
Connect exchanges, wallets, and brokers once — Nyx keeps them in sync every 15 minutes for the life of the fund. Crypto and equities sit in the same portfolio, priced the same way, with airdrop-spoofed tokens automatically excluded from NAV instead of quietly inflating it.
ACCOUNTING
Nyx runs a genuine double-entry ledger alongside your fund administrator — append-only, balanced, and deterministic. Every NAV strike is reproducible byte-for-byte. Every fee, every subscription, every redemption posts as a real journal entry, not a spreadsheet formula.
INVESTORS
One click turns real positions into a finished LP report — net-of-fee returns, statement of changes in NAV, full disclosures — in under a minute. Investors get their own portal and can ask your bots questions directly, with dollar figures shared only when you say so.
RISK
Gross, net, long, short — sliced by asset class, chain, venue, and source — updated live. Daily P&L attribution shows exactly what moved the number. Stress Lab runs scenarios and dollar-value-at-risk against your real book before you need the answer, not after.
AI
Nyx Analyst is an agentic chat that reads your general ledger and answers with citations back to the actual journal entries — not a guess dressed up as confidence. It proposes actions for you to approve, never executes on its own.
COMPLIANCE
Every action that touches money is logged, and on multi-manager funds, every material action needs a second set of eyes before it posts. Tax lots track themselves. Form PF readiness and K-1 data packages are one export away instead of a spreadsheet reconstruction project each quarter.
The alternative
A typical emerging fund's back office runs a finance hire (~$120K), a fund administrator (~$100K, often with a $25K–$60K annual minimum regardless of AUM), and a compliance advisor (~$80K). That's over $300,000 a year before a single LP report goes out — and none of it includes risk monitoring or an approvals workflow.
Nyx gives a solo GP or a two-person team the ledger, the risk desk, the reporting, and the compliance trail of a fund three times their size — for $999 a month. That's under $12,000 a year, roughly 4% of the back office it replaces, with nothing to hire, train, or manage.

FAQ
Nyx Fund is the operating system for emerging fund managers — crypto and multi-asset. It connects to your exchanges, wallets, and brokers, runs a real double-entry shadow ledger alongside your fund administrator, strikes deterministic NAV, accrues fees, monitors risk, and generates LP reports automatically — replacing a back office that would otherwise cost over $300,000 a year, for $999 a month.
Nyx Fund is built for solo and small-team fund managers running roughly $1M to $50M in AUM — crypto-native funds and multi-asset managers with a crypto sleeve — who need institutional-grade accounting, reporting, and risk monitoring without hiring a finance team, fund administrator, or compliance staff.
Nyx Fund is $999 per month per fund, billed monthly, with no per-seat fees and every feature included — the ledger, risk desk, reports, and compliance tools are not separate add-ons. That's under $12,000 a year. A traditional back office (a finance hire, a fund administrator with a $25K–$60K annual minimum, and a compliance advisor) runs over $300,000 a year for a comparable fund. It starts with a 14-day free trial that requires no credit card, and you can cancel any time.
No. Nyx Fund runs a genuine double-entry ledger — append-only, balanced, audit-traceable — that reconciles against your exchange and wallet data in real time. It is a shadow book that sits alongside your official administrator, not a replacement for one. The value is that you (and your LPs) get an institutional-grade, always-current NAV and audit trail between the administrator's periodic statements, and a second set of numbers to catch discrepancies early.
Nyx Fund is read-only and never places trades or moves funds. You connect read-only exchange API keys and public wallet addresses; keys are encrypted with AES-256-GCM, accounts support TOTP two-factor authentication with backup codes, and Nyx never requests withdrawal or trading permission. Your capital stays entirely under your control.
Yes. Nyx Fund connects to stock brokers — Alpaca, Tradier, Interactive Brokers, and SnapTrade (which reaches Robinhood, Schwab, Fidelity, and more) — alongside 98 crypto exchanges and 21 blockchains, so a multi-asset fund sees crypto and equities in one portfolio, one ledger, and one LP report.
Yes. Every fund gets a read-only LP portal where each investor sees their own capital account, isolated at the database level so one LP can never see another's numbers. Investors join by invite-only magic link — no password to manage — and can optionally ask questions through bots on Telegram, Slack, or Discord, with dollar figures shared only when you enable full disclosure for that channel.
Nothing from a paper or simulated account ever touches your real NAV. If you connect a TradingView or Alpaca paper-trading feed, Nyx keeps it in a completely separate, clearly labeled statement — it cannot post to your real positions, AUM, LP reports, alerts, or ledger under any circumstance.
Yes. Nyx Fund exports a Form PF data-readiness package (a structured summary plus monthly series covering the categories the form requires), tracks tax lots under your elected cost-basis method (average, FIFO, or HIFO), and generates tax-gains and tax-capital CSVs alongside a K-1 data package. These are data-handoff exports for your preparer, not a filing service.
Yes. Every fund gets a 14-day free trial with full access and no credit card required. If Nyx Fund doesn't fit how you run your fund, you lose nothing but the signup — the trial converts to $999 a month only if you choose to continue.
