Company

20 years focused on what happens between systems.

TomorrowX is an Australian-founded research and software company established in 2006, with R&D in Cyprus and team members drawn from Australia, Cyprus, Denmark, Germany, Greece, Ireland, the Netherlands, Sweden, the United Kingdom and the United States.

Our purpose and philosophy

The power of and.

TomorrowX binds technological capacity to human value. One is incomplete without the other.

TechnologyHow stuff works.

AnthropologyHow humans work.

TechnoanthropologyHow stuff works for humans.

The benefit is bound into the definition.

Technoanthropology is deliberately coupled. How something works and how it works for humans are not separate stages in the TomorrowX process. They are designed together.

That means every TomorrowX innovation and solution must carry a defensible benefit for the organisation, our communities and our environment. The benefit is not an afterthought, a separate impact programme or a promise added once the technology has been built.

TomorrowX: Data Mediation.Tomorrow, today.

A short introduction to the thinking, purpose and people behind TomorrowX.

Research and history

How the work evolved.

The work began with a practical question: can the behaviour around a running system be changed without forcing the system itself through another disruptive release?

  1. 2006

    The in-path discovery

    TomorrowX began as FMT, focusing on online fraud, risk and interaction control. A working fraud capability revealed something broader: data entering and leaving a legacy system could be observed and altered without changing the application underneath.

    From point solution to architecture

    Research and enterprise deployment tested whether the same foundation could support security, authentication, compliance, analytics and system augmentation. Gartner recognised the company as a Cool Vendor and IBM later became a partner and minority shareholder.

    Components, boundaries and black-box change

    Research formalised running systems as components with an outside purpose, a visible boundary and an internal implementation. The purpose was practical: identify a safe design surface where new behaviour could be mediated without reopening or disrupting the system inside. The boundary contract included messages, services and events together with security, performance, resilience, volume, location and other non-functional requirements.

    Multi-protocol mediation

    The engine expanded beyond a single web interaction model. Research focused on how protocol, message sequence, context and policy could be understood across different generations of enterprise technology. This became the foundation for defining and governing interactions across modern, legacy and operational protocols.

  5. 2013–15

    A separate layer and a parallel operating model

    Architecture and market research located a distinct operational layer in the interaction between systems. The aim was to make innovation possible across technology generations without forcing every requirement into an application release. That layer had to remain fully programmable, multi-protocol and governed by the same non-functional requirements and evidence expected of production systems.

    Composable architecture

    The work moved from programmable runtime control into a composable delivery model. Reusable capabilities, protocol definitions and non-functional controls could be assembled around an outcome, then registered in a catalogue for reuse. This marketplace thinking gave rise to the X Store: a way for a team, domain or enterprise to publish and exchange proven capability without centralising every deployment.

    The full operational lifecycle

    Research increasingly treated deployment as the midpoint rather than the end. Requirements, policies and non-functional constraints needed to remain connected to deployment, probes, telemetry, management, repair and retirement. In parallel, the target-state work formalised how a standardised Data Mediation foundation could be deployed and owned by decentralised teams across an enterprise.

    Data Mediation

    The accumulated work was brought together under one name. Data Mediation describes a fully programmable capability in the data path that can support multiple outcome classes across AI, cyber security, interoperability and assurance. CAP, Programmable Data Agents, the Editor and Console provide the technology foundation.
