Sunfox Technologies Raises $7 Million to Take India-Built Spandan ECG Platform Global

Dehradun-based medtech startup Sunfox Technologies has raised $7 million, or about ₹67 crore, in Series A funding to expand its portable cardiac-diagnostics platform Spandan across India and international markets.

The funding round was announced on October 7, 2026 and included investors Ashish Kacholia, Lashit Sanghvi, Alchemy Capital and 3one4 Capital. Sunfox plans to use the capital to expand domestic operations, strengthen research and development, build international distribution capabilities and pursue regulatory clearances in major overseas markets.

The development gives fresh momentum to an Indian medical-device company that has focused on making electrocardiography more portable and accessible outside conventional hospital settings.

Spandan Brings ECG Capability into a Portable Format

Sunfox has built Spandan as a compact electrocardiogram platform designed for use in homes, clinics, hospitals, telemedicine networks and public-health systems.

An electrocardiogram records the electrical activity of the heart and can help healthcare professionals identify abnormalities that may require further clinical assessment. Conventional ECG systems are generally associated with hospitals, diagnostic centres and clinics, while portable systems can extend basic cardiac assessment closer to patients.

Sunfox’s current Spandan ecosystem combines portable hardware, software and access to remote medical review. The company’s flagship Spandan Legacy 4.0 is described as a portable system capable of sequential 12-lead ECG monitoring using three electrodes and an Android application.

The company also offers other versions of the platform aimed at different use cases, including home monitoring and clinical environments.

A Smartphone-Linked Approach to Cardiac Assessment

One of the distinguishing features of Spandan is its use of a smartphone as part of the ECG workflow.

A healthcare worker or user can record the heart’s electrical signals through the portable hardware, after which the digital ECG can be analysed or shared for clinical interpretation. Sunfox says its wider ecosystem includes access to doctors who can review recordings remotely.

This model is particularly relevant in areas where specialist cardiac services are not immediately available. A health worker at a smaller healthcare centre can capture an ECG locally and share it with a physician or specialist at another location for assessment.

Such an arrangement does not replace emergency medical care or specialist diagnosis, but it can help move cardiac information more quickly between patients, frontline healthcare workers and doctors.

Sunfox Says Spandan Has Reached More Than 20,000 Villages

According to figures released by the company alongside the latest funding announcement, approximately 60,000 Spandan devices have been deployed across India, reaching more than 20,000 villages.

Sunfox also says its Spandan One platform supports cardiac screening of approximately five million patients annually.

These are company-reported deployment figures, but they highlight the scale at which portable diagnostic technologies can potentially operate when combined with telemedicine and distributed healthcare networks.

The company’s products have also reached healthcare providers across more than 1,800 PIN codes in India, according to information released around the funding round.

Rural Healthcare Is an Important Part of the Opportunity

India’s large geographical spread creates a particular challenge for specialist healthcare delivery. Advanced cardiac facilities and cardiologists remain concentrated in larger hospitals and urban centres, while patients in smaller towns and rural areas may need to travel significant distances for specialist assessment.

Portable diagnostic systems can help bridge part of that gap by allowing preliminary cardiac data to be recorded closer to the patient.

Sunfox describes a hub-and-spoke model in which nurses or healthcare workers at Primary Health Centres and Community Health Centres capture ECG recordings and transmit them to doctors at larger centres.

Where abnormalities are identified, patients can then be referred for further clinical evaluation and treatment.

The significance of the model lies not simply in miniaturising an ECG machine, but in linking portable hardware with digital communication and remote medical expertise.

New Capital Will Support Research and Expansion

Sunfox says the Series A funding will support three principal areas: expansion across India, further research and development, and preparation for international commercialisation.

The company intends to increase investment in engineering, clinical evidence and new cardiac technologies while expanding its domestic footprint.

It is also building regulatory, distribution and commercial capabilities for overseas markets, including the United States, Europe and Africa.

Sunfox already reports regulatory approvals in India, Ghana, Kenya, Tanzania and South Africa, while approvals are being pursued in the United States and European Union.

Entering those larger regulated markets would require the company to meet additional clinical, quality and regulatory requirements before wider commercial deployment.

From Dehradun R&D Venture to Medtech Company

Sunfox was founded in 2016 in Uttarakhand by Rajat Jain, Arpit Jain, Sabit Rawat, Nitin Chandola and Saurabh Badola.

The company began as a research and development venture rather than emerging from one of India’s conventional technology hubs. Its growth from Dehradun is noteworthy in a startup ecosystem often concentrated around Bengaluru, Delhi-NCR, Mumbai, Hyderabad and Pune.

Sunfox gained wider public recognition after appearing on the first season of Shark Tank India, where it secured backing from all five investors participating in its pitch.

The latest Series A represents the largest funding round in the company’s history and provides it with considerably greater resources for product development and international expansion.

Building Medical Devices in India

Sunfox also represents a broader shift underway within India’s healthcare-technology sector.

Indian companies have historically relied heavily on imported sophisticated diagnostic equipment across several categories. Domestic medical-device development is therefore becoming an increasingly important part of India’s wider manufacturing and technology strategy.

Portable diagnostic systems are particularly well suited to Indian engineering because affordability, compact design, low infrastructure requirements and ease of deployment can be as important as outright technical sophistication.

Products developed for Indian operating conditions can also find markets in other countries facing similar challenges involving rural healthcare access, specialist shortages and cost constraints.

Sunfox’s attempt to expand Spandan internationally will provide an important test of whether an Indian-designed portable cardiac platform can compete beyond its domestic market.

Portable Diagnostics Could Expand India’s Medtech Footprint

The value of technologies such as Spandan ultimately depends on reliable measurements, appropriate clinical validation, regulatory compliance and integration into established healthcare pathways.

Portable devices cannot replace specialist cardiac care, but they can make electrocardiographic information available in places where conventional diagnostic infrastructure is difficult to access.

Sunfox’s new funding gives the company an opportunity to strengthen the technology, build additional clinical evidence and expand the infrastructure needed to support doctors and healthcare institutions using the platform.

If successfully scaled across regulated international markets, Spandan could also demonstrate how Indian medical-device companies can move beyond domestic affordability-driven innovation and develop products with wider global relevance.

The $7 million Series A therefore represents more than another startup funding round. It gives an India-built cardiac-diagnostics platform additional resources to move from widespread domestic deployment towards a larger international medical-device business.
