Raising the floor for healthcare software

A clear ambition: make world-class healthcare infrastructure the default, not the exception.

Who we are

ESUS is a founder-led company building the backend that healthcare software should have had a decade ago. The scope is deliberately narrow: a FHIR R4–compliant, HIPAA-aligned platform that lets medical software teams ship fast without inheriting infrastructure debt, compliance complexity, or security shortcuts. The company is currently operated by its founder, Juan Manuel Panozzo Zenere (Concordia, Entre Ríos, Argentina), as a natural-person-operated venture. A Limited Liability Company is in formation and will assume all operations, contracts, and obligations upon incorporation; existing customers and partners will be notified in advance and all commitments will continue uninterrupted under the successor entity.

Our mission

Healthcare software has been slow to modernize. Integrations are painful, security is often an afterthought, and developers inherit decades of technical debt before they can write their first line of business logic. Our mission is for ESUS to become the infrastructure default — a platform that sets the quality floor for medical technology, so every team building in healthcare inherits security, interoperability, and developer experience without having to build those layers from scratch.

How we work

We build in focused iterations, ship on a short cadence, and obsess over the details most teams gloss over. Security, auditability, and multi-tenant isolation are product-level commitments, not add-ons. Every architectural decision is documented; every customer-impacting change is announced with notice; every incident is reviewed and shared transparently with affected customers.

Governance and legal status

Until the LLC is incorporated, Juan Manuel Panozzo Zenere, acting in a personal capacity, is the sole party responsible for the platform's operation, contracts, and obligations. This structure is fully disclosed in our Privacy Policy, where the LLC transition and successor-in-interest clause are publicly committed to. Investors, customers, and partners who require specific legal, compliance, or due-diligence information are welcome to reach out directly at hello@esus.health.

Security first

HIPAA-aligned from day one, not retrofitted. Encryption, audit logs, and tenant isolation built into the core — never an add-on.

Developer experience

FHIR without the pain. Clean APIs, typed SDKs, and documentation you'd actually want to read. If it's painful to integrate, we got it wrong.

Speed

From idea to production in days, not quarters. We remove the months of infrastructure work so teams can ship real healthcare software faster.

Scalability

Architected for millions of records and thousands of concurrent users — so the platform that runs your pilot is the same one that runs your enterprise deployment.
