Some business handovers are about products. This one is about trust. As Kary Nulisch prepares to retire and move into his next chapter, he has entrusted Orchestral with the ongoing operation and future development of The Mother. For more than 30 years, Kary and the Castlemark Consulting team have helped healthcare organizations solve the practical challenges of connecting data, systems and people across statewide health information exchanges. When Castlemark’s HIE customers needed a better way to manage their complex relationships and see clearly what was happening across their networks, Kary and his team built one. They affectionately called it ‘The Mother’ because it began life as “the mother of all spreadsheets”. It grew into a purpose-built CRM and analytics platform shaped by the real needs of HIE teams. We are proud, but more importantly, conscious of the responsibility that comes with Kary’s trust. Our job is to provide continuity for its customers, protect what makes The Mother valuable and work alongside its users to develop what comes next. Kary and Castlemark have made an enormous contribution to health information exchange and to the people working within it. We are honoured to carry one part of that legacy forward. Congratulations on your retirement, Kary. Thank you for trusting us with The Mother. #HIE

People rely on health data being right. Increasingly, AI does too. Orchestral provides the trusted data foundation and governance to support both.

Approving a model is one point in time. Knowing what data it is using, how it was assessed and whether it is still performing is an ongoing responsibility. Orchestral gives you that visibility.

Health already knows how to watch something that drifts. Lab tests get daily QC, drugs get postmarket surveillance, devices get adverse event reporting. Very little of that has been pointed at models, or at the data they read. Figures via Evolvance, May 2026, compiling Aon and Economist Impact. All industries.

Ingestion tells you the data arrived. It doesn't tell you it was right. Models are approved, but not whether it has drifted. Orchestral handles both.

A patient's record is assembled out of systems that were never built to work with each other. A model reading it inherits every one of those seams. That is the part we work on. So is the model.
