Coverage
Most firms spread these across a security master, a market data store, an IBOR, a config database and a reporting warehouse, then spend their days reconciling them. Masseef holds them in one system, so they agree by construction. Every domain on this page is built and running today.
The same depth in every domain.
Securities, issuers, identifiers, counterparties, credit ratings, calendars and currencies in one typed master. Where several vendors supply a value, versioned source rules pick one and record why.
From a plain bond to a swap on a basket of convertibles, typed and nested.
Positions, trades and transactions of every kind, from cash flows and fees to margin, repo and collateral, with their full history.
Corporate action events from several sources, matched into one record.
Prices, curves, surfaces and fixings from any vendor feed.
Indices and their constituents, as of any date.
Funds, share classes and fund-of-funds holdings.
Checks on every value, an exception queue with evidence, and security matching.
Curve and vol setups, vendor priorities and checks, kept as versioned data.
Valuations, greeks and sensitivities from each run, tied to the inputs and code version that produced them.
Orders and executions, settlement instructions, broker relationships, mandates, limits and restricted lists.
APIs, SQL, Excel, a desktop app and AI agents, all on the same data.
The data layer, not the whole stack. Masseef holds the data your order management, portfolio management and compliance systems act on, and gives them one consistent, versioned record. It doesn't route orders or keep the books.
Most firms begin with one: the security master, positions, or the vendor feed that breaks every week. We'll show you that one on a running system.
