Not long ago, the idea of a surgeon guiding a critical operation from thousands of kilometers away sounded like science fiction. Today, Zerintia HealthTech, a Spanish digital-health startup, is making it a reality. Their platform, 4RemoteHealth, uses 5G connectivity and augmented reality (AR) to unite medical professionals across operating rooms, ICUs, ambulances, and even patients’ homes — all in real time.

A Startup with Deep Roots and a Big Vision

Zerintia HealthTech was founded in 2023, but its roots go back a decade. As the company’s co-founder and chairman, Joaquín Fernández de Piérola, explains, the technology at its core had been quietly developing long before the company’s public launch.

The spark came when Vodafone Spain planned (but struggled) to broadcast a remote surgery via 5G at the Mobile World Congress. Rather than wait, Zerintia’s team adapted an industrial remote-connectivity tool (called 4Remote) in just three months to build 4RemoteHealth, a dedicated health-tech platform.

What Is 4RemoteHealth, and Why It Matters

At its heart, 4RemoteHealth is a software-as-a-service (SaaS) platform built for collaborative, real-time medical work. It integrates voice, video, clinical device data, and AR tools — all securely and with low latency.

Some of the key environments where it’s already deployed:

• Operating rooms: Surgeons can receive remote guidance during complex procedures, with experts drawing or annotating directly on shared video feeds via AR.
• ICUs: Remote specialists can support on-site staff instantly, no matter where the hospital is located.
• Ambulances: Perhaps one of the most critical uses — in collaboration with EuroGaza Emergencias, Zerintia connected ambulances so that emergency teams in the field can transmit live data (vitals, video, defibrillator info) to hospital specialists.
• Home care: Healthcare workers visiting patients at home can consult specialists via the platform, reducing the need for hospital visits.
• Training and education: Thanks to AR, students, interns, and other clinicians can attend real surgical operations live, even if they’re not physically in the operating room.

Real-World Impact and Global Expansion

Zerintia’s ambitions aren’t limited to Spain. Some of their most notable recent developments include:

• Ambulance digitization in Romania: In October 2025, Zerintia announced a contract with Romanian manufacturer Deltamed to connect 120 mobile ICU ambulances to the national emergency infrastructure via their platform.
• Connected ambulances in Europe: Their technology allows emergency centers to guide paramedics in real time, sharing vital clinical data, video, and more, which can speed up triage and stabilize patients even before they reach the hospital.
• Digital training and surgical demos: At Medica 2023, Zerintia showcased 4RemoteHealth by broadcasting a live surgery, demonstrating how remote experts can support complex operations.

The Business Side: Growth, Funding, and Long-Term Vision

Despite being relatively new, Zerintia HealthTech is scaling quickly. According to reports:

• They closed their first 10 months in 2023 with €130,000 in revenue.
• In 2024, they nearly tripled that, and by 2025 they aim to hit €1 million, with 80% of their revenue coming from international markets.
• Their business model relies on a subscription-based SaaS, which can snowball as they add more hospitals, ambulances, and clinics.
• They plan to raise another €2.5–3 million, building on earlier investments totaling €1.8 million.

Their long-term goal? To become a global leader in connected healthcare, enabling remote tele-assistance everywhere.

Why This Is a Healthcare Game Changer

1. Better patient outcomes
By connecting ambulances, operating rooms, and specialized centers, Zerintia’s technology helps bring expert care to patients who might otherwise wait or travel.

2. Training without boundaries
Surgeons and students can collaborate in real time, learning from experts without physically needing to be in the same room.

3. Resource optimization
Remote expert supervision means fewer unnecessary transfers and more efficient use of hospital staff.

4. Emergency response reimagined
On-scene paramedics can get guidance from specialists via video and vital-sign sharing — a real difference when seconds count.

Challenges and the Road Ahead

Of course, scaling this kind of solution globally comes with hurdles:

• Connectivity demands: Real-time video, AR, and device data require high-speed, low-latency networks like 5G.
• Regulatory complexity: Integrating clinical data securely means navigating strict privacy and data-protection laws.
• Adoption barriers: Convincing hospitals and EMS systems to adopt a new platform requires evidence, trust, and training.
• Sustainability: Their SaaS model needs to keep growing to sustain R&D, especially in emerging markets.

A Vision for the Future: Smarter, Connected Healthcare Everywhere

Ultimately, Zerintia HealthTech is doing more than selling software. They’re building bridges: between patients and specialists, small clinics and expert centers, and emergency teams and hospital consultants.

If their ambitions succeed, we’ll no longer think of hospitals as static places. Instead, care could come to us — through ambulances, through home visits, even through our devices — with the same expert oversight that only large medical centers used to provide.

In a world where healthcare often feels fragmented, Zerintia’s platform is a hopeful sign that the future could be more connected, more responsive, and more human — powered by technology, but shaped by the real needs of patients and professionals.
