Our story

Built by people who lived
the problem firsthand.

We have worked inside asset managers and ETF issuers and seen the same issue repeat itself — critical financial data scattered across spreadsheets, vendor exports, and hand-rolled scripts. Ptolemy is the tool we always wished existed.

Origin

The spreadsheet problem has a better solution.

Every asset manager we worked with had the same setup: a patchwork of Bloomberg exports, custom Python scripts, and shared drives full of half-maintained Excel files. No one had data they could truly trust.

“Good data infrastructure is invisible. Bad data infrastructure is all you think about.”

Ptolemy started as the internal tool we built to solve this. A single, structured source of truth for instruments and markets — accessible by the research team, the portfolio system, and the risk engine, all from one API.

Roadmap

Built in deliberate phases.

Each phase delivers standalone value while laying the foundation for the next — from the data foundation we're building today through to a complete financial operating system.

Phase 1
● Building now

The data foundation

A structured, API-native home for your instrument universe and the data that flows through it — accessible via REST API, CSV/Excel, and a graphical dashboard.

  • Instrument master with custom, typed attributes
  • Time series — prices, NAV, proprietary signals, holdings
  • Markets, listings, calendars & suspensions
  • Role-based access, audit trail & multi-workspace isolation
Phase 2
○ Planned

Operations

Operational integrity layered on the data foundation — reconcile against your sources and enforce the checks and controls your processes depend on.

  • Reconciliation engine
  • Checks and controls
  • Exception handling and alerts
Phase 3
○ Planned

Key operational processes

The core fund-operations workflows, built on clean data and operational controls.

  • Applications and redemptions management
  • PCF creation
  • NAV creation and validation
Phase 4
○ Planned

Books of record

The Investment, Accounting, and Cost-base Books of Record, built on the data, controls, and processes already in place.

  • Investment Book of Record (IBOR)
  • Accounting Book of Record (ABOR)
  • Cost-base Book of Record (CBOR) — capital-gains tracking
Phase 5
○ Planned

Order & trade management

Connecting the data and book-of-record layers to execution, with order management, rebalancing, and trade-lifecycle workflows.

  • Order management
  • Portfolio rebalancing
  • Trade lifecycle and execution
What we believe
i.
Precision over convenience
Financial data carries real consequences. We build every feature with correctness as the primary constraint, not speed of delivery.
ii.
Infrastructure, not software
Ptolemy is designed to sit at the foundation of your investment operations — reliable, programmable, and invisible when it's working well.
iii.
Respect for the practitioner
We build for people who know their domain deeply. Our UI gets out of the way; our API is a first-class citizen.
100%
API-first — every feature is accessible programmatically

Custom attributes per instrument type — no hard limits
Multi-tenant
Workspace isolation built in from day one
