Built for the complexity of futures and derivatives.

Theorem helps buy-side and sell-side firms bring together financial data across brokers, counterparties, and internal systems. Our platform supports matching, reconciliation, and consolidated reporting across P&L, collateral, positions, and operational activity.

We combine flexible software with operational expertise to help your team investigate discrepancies, manage reporting requirements, and follow through with counterparties when issues remain unresolved.

The records don’t always arrive together.
Or agree.

A broker file arrives late. An allocation appears in one system but has not reached the clearing account. A correction resolves one discrepancy while leaving another open. Your team still needs to establish what happened and what requires attention.

Theorem normalizes data across sources and brings the relevant records together for reconciliation and reporting. That gives your team a consistent basis for investigation, while recognizing that complete information and counterparty follow-through remain essential to resolution.

Finding a break starts the work of resolving it.

A discrepancy report can show your team where records differ. Establishing the cause may require additional data, a conversation with a clearing broker, or follow-up after a partial correction.

Theorem is both a technology provider and a service partner. Alongside the platform, our team can help investigate data issues, communicate with counterparties, and follow unresolved breaks through the correction process.

The work we take on is defined with your firm. Resolution still depends on the relevant parties supplying information, confirming details, and completing corrections.

Our Approach To AI

New technology requires clear responsibility.

We evaluate emerging AI models against the same operational and security principles that guide our other technology decisions: defined access, appropriate controls, and human accountability.

The ability to automate a task does not establish that it should be automated. Our approach considers the data involved, the consequences of an incorrect result, and who remains responsible for reviewing the work.
