About Castellum Digital Indonesia
Castellum Digital Indonesia (CDI) is a locally rooted technology firm with deep expertise in health information systems, data interoperability, and digital transformation—particularly in strengthening government systems at the national and subnational levels.
Established in 2021, CDI has grown and thrived amid the dynamic and evolving landscape of health digitalization in Indonesia. Over the years, we have navigated policy changes, shifting priorities, and technological transitions—while continuing to deliver solutions that are relevant, resilient, and impactful.
We've had the privilege of supporting various development partners and national stakeholders across Indonesia in designing and implementing scalable, context-specific digital solutions. Our team works across the digital health ecosystem—from strategic system design and implementation to training, technical assistance, and ongoing evaluation.
What makes us different is that we do not sell a single product or pre-packaged solution. Instead, we work collaboratively with clients, stakeholders, and users to design, adopt, and adapt sustainable and scalable information systems and digital tools that truly improve services.
Grounded in values of collaboration, innovation, and long-term commitment, Castellum Digital Indonesia is proud to be a trusted partner for those seeking to build stronger, more responsive health systems.
