Investment data infrastructure — platform foundation

Investment data infrastructure
built for governed analytics

Governed computation on ungoverned data is not defensible. Before the analytics workflow can produce audit-ready output, the data layer needs to be structured, versioned, and traceable. We build the investment data infrastructure that makes every governed run reproducible from source to output.

Why data infrastructure comes first

The gap most mid-market funds have

Analysts spend Monday morning downloading CSVs from Bloomberg, correcting column names, and manually updating a shared database before any analysis can run. That is not analytical work — and it means every downstream output inherits the fragility of the input process.

What structured data infrastructure changes

When portfolio data, benchmark series, NAV history, and position files live in a versioned, queryable data store with defined schemas and quality checks — every governed workflow run can reference a traceable input. The audit trail starts at the data layer, not at the computation.

Connection to the governed analytics workflow

Alpha Quant Agent's methods consume structured data inputs. A properly built data layer means runs are reproducible across time, inputs are auditable, and anomalies in source data are caught before they propagate into a client report.

What we build

Investment data infrastructure components

Structured ingestion pipelines

Automated, scheduled pulls from Bloomberg, Refinitiv, custodian feeds, prime broker files, or internal systems. Data arrives in defined schemas — no manual CSV handling, no column-name corrections.

Investment data catalog

Metadata layer covering asset universe, benchmark definitions, data source lineage, update frequency, and field-level documentation. Every analyst knows what data exists, where it came from, and when it was last updated.

Portfolio and position database

Structured tables for NAV history, position data, benchmark constituents, and corporate actions — designed for the query patterns that quant analytics actually require. Built on your Azure tenant, not a shared cloud database.

Data quality and validation gates

Automated checks that run on arrival: missing fields, stale timestamps, outlier values, schema violations. Failures are flagged before a workflow run is triggered. No silent bad data in a governed output.

Data versioning and point-in-time access

Every data update is versioned. A run from six months ago can be reproduced against the exact data that existed at that point in time — a requirement for any serious regulatory audit or LP query.

Governance pillars

Data integrity from source to output

Data lineage from source to output

Every field in every governed run traces back to a source record with a timestamp and ingestion log. No unattributed inputs.

Your data never leaves your Azure tenant

Ingestion pipelines, databases, and catalog layers are built and deployed inside your environment. Nexqion has no ongoing access after handover.

Point-in-time reproducibility

Data versioning ensures any past run can be reproduced exactly as it was executed — input state, method version, output — for regulatory audit or LP query response.

Quality gates before every run

No governed workflow run can start if the upstream data has not passed validation. Bad data is caught at ingestion, not discovered in a client report.

Mandate examples

Typical data infrastructure mandates

Single-fund investment team

Data layer build

  • Audited existing data sources — Bloomberg terminal, custodian files, internal Excel models
  • Designed and built a structured PostgreSQL database on Azure with defined schemas
  • Implemented automated ingestion from three data sources with quality validation
  • Connected to Alpha Quant Agent as the primary analytics consumer

Outcome

Analysts reclaimed Monday morning. Every governed run references a traceable, versioned input.

Multi-strategy fund

Data catalog and lineage

  • Mapped 12 data sources across strategies with inconsistent field naming and update cadences
  • Built a unified data catalog with source lineage, field definitions, and freshness monitoring
  • Implemented a point-in-time query layer for audit and regulatory reproduction

Outcome

Any historical run can be reproduced exactly — inputs, methods, and output — for regulatory or LP review.

Migration mandate

Excel and shared drive to structured store

  • Extracted and normalised 5 years of historical NAV, position, and benchmark data from Excel
  • Validated completeness and consistency against custodian records
  • Migrated to versioned database with rollback capability and schema documentation

Outcome

Historical data is now queryable, auditable, and ready to serve the governed analytics workflow.

How we run the mandate

From audit to production data layer

01

Audit

Inventory existing data sources, formats, quality, and gaps.

02

Design

Define target schema, ingestion patterns, and quality rules.

03

Build

Implement pipelines, database, catalog, and validation layer.

04

Validate

Confirm data integrity, reproduce historical runs, hand over with runbook.

Typical engagement: 6–12 weeks depending on source complexity and data history depth.
