Our story

Built by the engineers who saw it from the inside.

  

In 2005, the future founders of xyt met while building and operating real-time analytics at major investment banks. Trading activity was fragmented across venues, instruments and protocols, with no consistent way to reconcile it into a complete market view. xyt was founded in 2014 to help market participants reconcile that complexity and turn fragmented trading data into reliable market intelligence.

Today, as xyt, we process and normalise data from more than 120 venues, combining it with clients’ order and execution data where needed. We deliver market-structure analytics, TCA and analysis-ready datasets that help firms find liquidity, evaluate execution, improve performance and evidence best execution.

Clients can access this market intelligence through our web platform, APIs, AI and datasets. Where standard products do not fit, our data scientists and engineers design and build bespoke solutions around each client’s data, methodology, workflows and objectives.

What we stand for

Trust begins with the evidence.

 An independent perspective, rigorous methodology and close attention to how markets actually trade - these are the foundations of every insight we deliver

Independent by design

Majority employee-owned, with no parent running an exchange, a broker or a venue. The same record serves both sides of every conversation, which is exactly why both sides can use it.

Accuracy that stands up

Every print classified, every correction stripped, every methodology documented and in the open. Numbers built to be interrogated by committees, members and regulators.
