Kardi Ai raises €5.3 million, plans heart-monitoring expansion to India

Kardi Ai, a medical technology start-up based in Prague, Czech Republic, has raised €5.3 million in a Series A funding round led by the German health-technology fund Callisto Health, according to reports published on Wednesday, 11 November 2026. The round values the company at €23 million. Kardi Ai makes a chest strap with an ECG sensor, paired with a mobile app that uses artificial intelligence to analyse heart-rhythm recordings over long periods. It plans to use the money to expand into Germany, India, the United Arab Emirates and Singapore and to build models that estimate a person's risk of arrhythmia, or irregular heartbeat.

Kardi Ai's business is built around that idea: a strap people can wear during normal life, and software that flags patterns for a doctor to check. The company's description of the product as decision support, not diagnosis, matters, because medical devices that claim to diagnose face stricter approval rules in most countries.

For Peepals Global readers, the notable detail is India on the expansion list. A small European medtech firm has chosen India as one of only four target markets. Entering India will require the company to meet Indian medical-device rules, find hospital partners and price the product for Indian patients, none of which the reports describe in detail yet. For Indian hospitals, cardiologists and health-tech founders, the move signals more foreign competition in wearable heart monitoring, and possible partnership openings for local distributors and clinics.

The second use of the money is software. The company says it will build predictive models that estimate a user's risk of arrhythmia from the recordings, moving from recording what has happened towards flagging what might happen. Any such risk score would be the company's own estimate, to be checked by doctors, and the reports do not give a timeline for it.

The round also shows how European health start-ups are being funded: a specialist health fund leading, with venture funds and a bank-backed seed vehicle alongside. Česká spořitelna, one of the backers behind Seed Starter, has offered the product to its own staff since 2024, one report says, an example of an investor also acting as an early customer.

Peepals calculation: The €5.3 million raised equals about 23% of the €23 million valuation (5.3 ÷ 23 ≈ 0.23). Put another way, the valuation is about 4.3 times the new money (23 ÷ 5.3 ≈ 4.34). Our calculation from the reported figures.

Short-term: Kardi Ai will use the funding to start entering its four target markets and to develop its arrhythmia-risk models.

Long-term: If it wins approvals and hospital partners abroad, the company could become one of several foreign wearable-ECG providers offering remote heart monitoring in India.

Who is affected: Patients who need long-term heart-rhythm monitoring, cardiologists and hospitals in the target markets, Indian health-tech firms in the same space, and the company's investors.
