McCrae Tech is a global health-technology group founded by Ian McCrae, the entrepreneur behind Orion Health. It brings together three independent companies - Amalga, Indexity, and Orchestral, each advancing healthcare in a unique way.
From hospitals to national AI infrastructure, these companies share one ambition: to make healthcare more connected, intelligent, and human.
Amalga - Hospitals Without Silos
Hospitals run on information, but too often that information sits in disconnected systems that slow care.
Amalga, led by CEO Niru Rajakumar, builds modular hospital systems that join data, departments, and workflows into a single, mobile-ready platform.
Amalga supports over 30 hospitals and 5,000 beds across New Zealand and Southeast Asia, including a decade-long programme that created a single administrative backbone for hospital care across the South Island - serving 1.2 million people.
“Amalga captures data once and uses it everywhere,” says Rajakumar. “That means less duplication, fewer delays, and more time for patients.”
Access is easier because we’re device agnostic and mobile-friendly whether the clinicians is on the ward or remote. Users can deploy Amalga in components, such as in one department, and then scale it to other departments. Features including a scheduling engine for hospital theatres, a single and shared wait list, a unified patient record and a workflow engine to enable daily management of patients from both inside and outside the hospital.
Amalga also provides rich back office and ERP functions, ranging from revenue and P&L through to KPI targets for patients and clinical performance.
Earlier this year, Amalga delivered a major milestone in New Zealand’s digital health infrastructure, completing a 10-year regional programme to establish a single administrative backbone for hospital care across the South Island.
“TheSouth Island now has a single source of truth for patient administration and care episodes. This means fewer handoffs, faster treatment, and smoother journeys for patients, no matter where they live,” says Rajakumar.
The company’s next 12 months focus on expansion across New Zealand’s private and public sectors, already live at Franklin and Kaweka hospitals, and continued roll out across Asia with new deployments at Rutnin Eye Hospital (Thailand) and Sun Group International Hospital (Vietnam), both going live in early 2026. Amalga is also exploring partnerships in Latin America and the Middle East to integrate AI into its platform.
Indexity - Turning Health Data Into Intelligence
Indexity focuses on transforming fragmented health data into structured, governed intelligence through its Health Intelligence Core - a clinically native data foundation that standardises information from HL7, FHIR, CCDA, genomics, and social sources.
By providing a consistent, auditable framework for data, Indexity enables faster research, better policy, and AI models that operate on trusted information.
“Healthcare data is vast, but meaning is scarce,” says Lucy Porter, Director of McCrae Tech. “Our goal is to make health data useful - to turn every record into insight that supports real-world decisions.”
Indexity’s roadmap includes extending its Health Intelligence Core into new international partnerships and integrating additional datasets for precision medicine and public-health analytics.
Orchestral - The Health AI Orchestrator
Orchestral, led by CEO and McCrae Tech Director Lucy Porter, is creating a new category in healthcare technology: the Health AI Orchestrator.
Where data platforms simply store information and algorithms operate in isolation, Orchestral connects and governs them through an orchestration layer that embeds AI directly into clinical and operational workflows.
Its architecture powers New Zealand’s Government-backed Algorithm Hub - the world’s first national AI Orchestration Layer — which processes over 30,000 algorithm requests each month and scaled seamlessly during COVID-19 to deploy new predictive models within days.
“We’re not another data platform or AI vendor,” says Porter. “We’re building the orchestration layer that makes every algorithm work together - safely, transparently, and at scale.”
Over the next year, Orchestral will refine its large U.S. site, explore government partnerships across the Middle East and Asia, and continue defining the global category of Health AI Orchestration.
A Shared Vision for Smarter Healthcare
Although Amalga, Indexity,and Orchestral operate independently, they share a common direction: building technology that learns, adapts, and delivers measurable results.
From re-engineering hospital systems to governing national AI, McCrae Tech’s companies are designing the digital foundations for healthcare that works - for clinicians, for systems, and for people.
