One record.
Every system.
Now and next.
Open record.
Open integration.
Open future.
OpenFinance gives institutional finance a common language. The semantic data model the team first built in the 1990s, sold to SS&C, and then rebuilt as the foundation of OpenFinance in 2001 — has been continuously developed ever since. Thirty years of model lineage. Twenty-five years as OpenFinance.
Today the record services over $4 trillion in AUM, and integrates with everything the institution runs — its own systems, its customers’ systems, the regulators’ frameworks — now and in the future.
And OpenFinance is the distribution framework that syndicates ALPHA’s decision science — Northfield risk models, the optimizer, and portfolio implementation, together with Market76 personalization and performance evaluation — to anywhere in the organization: any workflow, any dataset, any application it already runs.
Open.
Integrated.
Always.
Better decisions need better science, better information, and better expression — and the only way to compound all three is to keep the platform open. Closed systems force the institution to choose between what its vendor recorded and what it actually needs to know. Open systems let the institution decide.
OpenFinance has been doing open for thirty years — as architecture, as culture, as strategy. Every product reads and writes through a published semantic model. Every interface is documented. Every record is the institution’s own. That posture is the moat.
It is what lets ALPHA push decision science into — and pull useful information back out of — any system, application, or workflow the institution runs. A ubiquitous reasoning layer, not another silo to tend.
The customer benefit is direct: faster decisions, more of them, on a record they can trust and verify — without ripping out anything they already run.
One record.
Five products.
Each product is independently purchasable and individually deployable, sharing the same semantic foundation in continuous development since the 1990s. Open architecture throughout — designed to work with the institutional stack you already run, not replace it.
The semantic core. PAIX is the first commercial semantic data model for institutional finance — a representation of what a position, a transaction, and an instrument are, independent of any single system’s schema.
Designed in the late 1990s, sold to SS&C, rebuilt as the foundation of OpenFinance from 2001 forward.
The institutional record at scale. Over $4T in AUM serviced, held in the PAIX semantic model. Multi-asset, multi-jurisdiction, multi-customer — designed for institutional firms whose own customers are institutions.
Harmonization, not replacement. Accounting Book of Record, Performance Book of Record, and Security Master delivered against the same semantic model — so the books agree because they read from one record, not because reconciliation forced them to.
OpenFinance integrates with everything the institution runs — its own systems, its customers’ systems, the regulators’ frameworks — now and in the future. ALPHA Open API exposes the record to every consumer that needs it.
Integration stops being a project. It becomes a property of the platform.
Continuous aggregation, quality assurance, and reconciliation across the institutional footprint. The record is verified against itself across systems and counterparties — the discipline that makes the “one record” claim defensible at $4T scale.
Open is the discipline.
The same group has held one position for thirty years: the institutional record belongs to the institution, and the platform’s job is to make it readable by every system the institution runs. The first model shipped in the 1990s. SS&C acquired it. In 2001 the team rebuilt it as OpenFinance, with the same conviction and a wider remit.
Every product on the Information pillar — PAIX, Data Lake, ABOR / PBOR / Security Master, Systems Integration, Aggregation — descends from that lineage and is designed to be integrated, replaced, extended, or read from systems we don’t own. The footprint at over $4T in AUM is the result of that discipline, not the reason for it.
How the record helps make
better decisions.
The science and the personalization are only ever as good as the record they reason on. Inside ALPHA, the methodology reads positions, transactions, and instruments directly from PAIX — no translation layer, no reconciliation lag, no information lost between systems. The customer’s decisions get faster, more complete, and more defensible — without ripping out anything they already run.
Methodology needs a record.
Risk models and optimizers are only as good as the record they read. Inside ALPHA, the methodology is no longer one analytical layer over many books — it sits directly on the OpenFinance record, with positions, transactions, and instruments resolved in PAIX semantics.
PAIX as common language.
The semantic model becomes the platform’s lingua franca. Every capability — Science, Information, Personalization — reads and writes through PAIX. The ALPHA Open API exposes the same record to the institution’s own systems, its customers’ systems, and the regulators’ frameworks.
Decisions, traced end-to-end.
What a position is, what was decided about it, why, and what was expressed downstream — all on the same record. Reasoning is traceable from raw position through model output through client-facing narrative. One record. Many readings.
One record.
Made for what comes next.
OpenFinance had been a data infrastructure provider to Northfield for nearly a decade before the three firms partnered in 2025 to create ALPHA — a decision platform built on the conviction that better decisions require better methodology, better data infrastructure, and better expression of reasoning to every audience the institution has to reach. The record is unchanged. Its reach is wider.
