About

The intelligence layer for modern clinics

OtterSG is an AI-powered clinic management and EHR platform that brings clinical, operational, and financial workflows together in one system so clinical teams spend less time on screens and more time with patients.

Our mission

Less clutter. More intelligent care.

Healthcare runs on fragmented tools - separate systems for records, scheduling, billing, and consultations that pull clinicians away from patients. OtterSG was built to close that gap: one intelligent system that handles the admin, so care stays at the centre.

What we do

One system for the whole practice

Everything a clinic needs to run - clinical, operational, and financial - brought together in one connected system instead of a stack of disconnected tools.

Unified workflows

EMR and clinical records, scheduling, billing and finance, inventory, and built-in teleconsultation in a single interface instead of stitched-together tools.

AI built in

AI-powered workflows that reduce administrative work and support documentation quality, so clinical teams can focus on patients.

Hybrid care

One continuous workflow across in-clinic and remote consultations, so care continues without switching systems.

Configurable modules and multi-currency support, from a single clinic to multi-site groups.

Our approach

Built for high-trust healthcare

OtterSG is designed around data protection and interoperability: secure, encrypted handling of clinical data and integration pathways aligned with national health initiatives where applicable.

  • Data encryption

    Clinical data is encrypted in transit over secure connections.

  • Interoperable by design

    Built to connect with the systems and registries each market requires.

  • Role-based access control

    Granular permissions so the right people see the right data.
