The healthcare sector is embracing artificial intelligence like never before. Several startups have just closed major funding rounds to scale their AI solutions. These innovations focus on everything from training healthcare workers to delivering remote treatments.

One company is tackling the chronic nursing shortage in the US. Stepful raised $55 million to expand its AI-powered workforce training platform. The platform replaces outdated, slow training methods with a digital system embedded inside hospitals. It guides learners through instruction, clinical simulations, and assessments. The system also uses data feedback to improve over time.

The shortage of nurses and healthcare workers is severe. Registered nurse supply grew by only 1% between 2022 and 2025, while demand rose by 3%. That leaves nearly 300,000 nurses short nationwide. Hospitals spend $97 billion yearly on temporary contract staff because traditional schools can’t train fast enough. Stepful’s “school-as-a-service” model aims to fix this structural problem by training workers directly within health systems.

AI Bringing Care Home with Virtual Physio

Across the pond, Flok Health is innovating treatment delivery. It raised $12.5 million to grow its AI-led physiotherapy service in the UK. The app offers video-based assessments and treatment for back pain, one of the most common reasons for disability and time off work.

Flok’s system is the first in Europe to get regulatory approval to fully diagnose, triage, treat, and discharge patients autonomously. It operates within the NHS and has reached over 2.4 million patients. The AI clinic cuts waiting times, saving clinicians hundreds of hours each month. Over 80% of patients say the AI care matches or beats in-person physiotherapy.

Patients complete an initial assessment on their phone. The AI then decides if they should enter the digital pathway or receive in-person care. Weekly video sessions, guided exercises, and pain management all happen through the app. Human clinicians stay available for complex cases or questions.

Building Connected Healthcare Across Europe

Meanwhile, Semble is growing its platform to connect healthcare providers across Europe. It secured £30 million to expand its digital infrastructure. Semble’s system links hospitals, clinics, and community care with shared records and workflows.

This integration simplifies communication and coordination, which has been a challenge for European health systems. By streamlining data flow, Semble helps providers deliver better care faster. The new funding will help the company scale and deepen its reach across multiple countries.

These three companies highlight how AI is reshaping healthcare on different fronts. Stepful targets workforce training, Flok Health delivers frontline treatment, and Semble connects health services. All three raised tens of millions to grow quickly, driven by urgent demand and clear value.

Behind these efforts lies a common problem: healthcare systems struggle to meet patient needs due to staff shortages and outdated processes. AI offers a way to close those gaps. It can train workers faster, deliver care more accessibly, and improve coordination between providers.

But AI isn’t replacing humans. It frees clinicians to focus on complex, high-value tasks while routine functions become automated. Patients get faster care without compromising quality. The result is a more efficient and resilient healthcare system.

As these startups scale, watch for AI to become a standard tool in hospitals and clinics. It’s no longer just a tech experiment but a practical solution with measurable impact. The healthcare sector is evolving, and AI is leading the way.
