Institutional
The highest tier of engagement with NautilusTrader: a direct relationship for proprietary trading firms, hedge funds, market makers, asset managers, family offices, and other financial institutions trading at scale. Individual professional traders at that scale qualify on the same terms. It is not a separate product. You can run Pro or the Cloud Platform and still work with us directly.
Why official
The engine is open source by design. You and your auditors can read its logic and verify how it behaves, rather than trusting a black box. The more serious the stakes, the more that transparency matters.
The moment you fork the open-source NautilusTrader, you take on its maintenance and security burden: patch review, dependency audits, and release validation become yours to carry. The institutional tier keeps you on a supported, certified line of official Nautilus, so your engineering effort goes into your strategies and operations rather than into maintaining a private fork.
NautilusTrader has been built and maintained for over a decade, and because the engine is open source, your ability to run it never depends on us alone.
Quality assurance
Signed, reproducible, version-pinned builds with additional review, carrying our Nautilus Certified attestation. Official release artifacts carry SLSA Build Level 3 provenance for wheels and sdists, Sigstore-attested SPDX SBOMs for container images, and signed checksum manifests. All are verifiable with standard tooling by auditors, counterparties, and limited partners (LPs). Each certified build also carries the determinism and auditability properties of the engine:
Attribution and support
Flow attributed to Nautilus can open a direct line to the core team.
Attribution
Nautilus tags integration and order activity as running on the engine by default, so that flow already counts, in aggregate, toward the public totals we attribute to Nautilus. There is nothing to opt into and nothing extra to set up. We never name you or share your identity; your flow only ever appears as part of the public Nautilus totals. The tags stay in place. We assess attributed flow on the same basis whether it comes from an individual or an institution. To open a direct relationship, confirm with us which tagged flow is yours.
Direct support
A dedicated channel straight to the people who build Nautilus. It covers answers to well-scoped questions, priority investigation of reproducible production issues, and priority remediation of confirmed defects within the supported NautilusTrader codebase.
Architecture reviews, strategy-system design, proprietary adapter audits, custom development, and general technical consulting fall outside direct support and need a separately scoped commercial engagement.
Eligibility
You qualify through either:
Qualifying on attributed flow rests primarily on verified live trading activity and on how central NautilusTrader is to your production environment. Capital under management, planned deployments, paper trading, backtesting, and projected future volume do not qualify on their own.
Get in touch
Whichever path fits, the next step is a conversation about qualification and scope, not technical review. If you are trading live, tell us about your setup and the venues you trade; we assess scale case by case against your markets and flow. For a contractual engagement, tell us what you need it to cover. Reach us at institutional@nautilustrader.io.
