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 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 and never executes on its own, remembers your fund's context across conversations, and rides along as a copilot on every page of the app. Autonomous missions run it on a schedule — morning briefs, risk sweeps, strategy critiques — reporting back without you asking.
STRATEGY LAB
Build a strategy visually or drop into a code node and write the logic yourself — same deterministic engine either way, so identical inputs always produce the identical result. Backtest long and short at up to 3× leverage with real margin interest, funding costs, and a modeled liquidation path, then walk it forward across rolling out-of-sample folds before you trust it. Every run is simulation, strictly segregated from your real book — nothing here touches NAV, positions, or your LPs unless you approve a memo.
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's Strategy Lab lets you build a trading strategy with a visual node-graph builder or a sandboxed JavaScript code node, then run it through a deterministic backtest engine — the same strategy and the same data always produce the identical result. You can test long and short positions with up to 3× leverage and realistic costs (margin interest, funding, a modeled liquidation path), validate with walk-forward out-of-sample folds, and run portfolio backtests across multiple strategies as one book. An AI improve loop — strategy_improve missions — has the Analyst critique a strategy against a benchmark library and propose revisions you approve. Backtests are simulation, strictly segregated from your fund: they never touch real NAV, positions, or LP reports, and Strategy Lab — like the rest of Nyx Fund — remains read-only and never places a trade.
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.
