TeleSync

About TeleSync

TeleSync began with a simple observation: in a video consultation, a doctor can see and hear the patient, but cannot examine them. We are building the missing bridge, so that distance no longer decides the quality of a check-up.

Our Mission

Healthcare professionals in telemedicine often rely mainly on video calls and patient-reported symptoms, without enough objective examination data. Our mission is to bridge that care gap by extending real examination capability to rural, underserved, elderly and homebound populations, using a portable device and the smartphone people already own.

What we set out to do

Our Objectives

Five goals guide every decision in the device, the app and the dashboard.

Cardiopulmonary assessment

Enable accurate digital recording of heart and lung sounds through guided placement and signal-quality assurance.

Comprehensive vital sign monitoring

Collect key vital signs, including heart rate, SpO₂, temperature and blood pressure, within one standardised workflow.

User empowerment and accessibility

Provide a simple guided application that helps non-expert caregivers and community health workers examine accurately.

Secure data management and connectivity

Support offline-first capture, encrypted storage and secure synchronisation whenever connectivity is available.

Clinician-centric decision support

Deliver structured, reviewable examination data that supports diagnosis, follow-up, triage and escalation.

What TeleSync offers

  • Objective and reviewableHeart and lung recordings and vital signs reduce reliance on subjective verbal descriptions.
  • Bridges the care gapExtends examination capability to rural, underserved, elderly and homebound populations.
  • Earlier detectionQuality checks and abnormal findings support faster recognition of deterioration.
  • Works in low-connectivity settingsOffline-first design with store-and-forward synchronisation supports continuity of care.
  • Cost-effective and scalableA portable device and ordinary smartphones support broader deployment and fewer avoidable referrals.

Our Story

Three of us, three paths to the same idea. In our own words, here is what inspired each of us to create TeleSync.

Research and Development Specialist

My experiences in scientific research and representing Thailand in one of the world’s most prestigious science and engineering competitions, as well as many international innovation exhibitions, shaped my approach to solving real-world problems. Years of research taught me how to apply scientific concepts to practical solutions that could make a real difference in society. My interests began to shift toward medicine and through my volunteer work in hospitals and underprivileged communities I saw first hand the challenges of healthcare accessibility. I am thrilled to be part of the TeleSync team, bringing together my research background and these experiences to work alongside passionate individuals in making healthcare more accessible.

Chief Commercial Officer

My antibiotics research in aquaculture helped me see how biological research connects to the health and livelihoods of communities. Developing an LLM-integrated RAG ChatBot then showed me the value of translating scientific knowledge into practical tools that people can use. As my interests in biology became increasingly focused on medicine and human health, I wanted to bring that same approach to healthcare. This inspired me to aid in the development of Telesync, providing a way to connect patients and healthcare professionals through accessible technology; thus, allowing me to extend my motivation to support communities from aquaculture to human care.
