What BondFoundry is — and what it isn't.
Two truths, one codebase. The bond desk gets a credible agent surface. The auditor gets a complete control mapping. We are deliberate about not over-claiming on either.
Is.
- A self-hostable AI assistant for the buy-side fixed-income desk
- The working reference implementation of FINOS AI Governance Framework v2.0
- Claude-backed pricing, risk, scenarios, curve ingestion, FIX 4.4 OMS
- MIT-licensed; fork-friendly; designed to swap into other domains
Isn't.
- A managed SaaS — you run it in your tenant
- A replacement for BlackRock Aladdin, SimCorp Dimension, Charles River, or Bloomberg AIM
- A pricing engine for live trading without validation — vanilla bonds are parity-tested; callables / FRNs / inflation-linked are scaffolded
- A general-purpose chat assistant
The framework needed a runnable artifact.
FINOS AIGF v2.0 shipped 23 risks and 23 mitigations as a Markdown taxonomy. The cost of that framework-agnostic format: no runnable artifact for new adopters to study, audit, or fork. The
finos/air-accelerator repo is the slot waiting to be filled.
BondFoundry is that artifact. Every AIGF v2.0 risk has a mapped mitigation in code, every mitigation has at least one passing eval case, every audit row carries the framework reference an external auditor needs to verify coverage. The CI gate fails any PR that drops AIGF coverage below 85%.
It was originally built for the buy-side fixed-income desk — the kind of team that already prices bonds in QuantLib, holds positions across USD / EUR / GBP / JPY books, and would like a Claude-backed analyst on the desk without handing the keys to a vendor SaaS. While building it we realised the governance machinery underneath was reusable, so we shipped it as the FINOS reference implementation too.
MIT. Fork it. Swap the domain.
BondFoundry is MIT-licensed. The full source is on GitHub. The control plane (policy gate, audit chain, HITL envelopes, eval harness, evidence pack CLI) is designed to fork into other domains: loans, derivatives, equities, structured products. The fixed-income engine is the example; the control plane is the point.
BondFoundry is built by Neullabs. We focus on governed AI in capital markets and adjacent regulated workflows.
