AWS Pioneers Project

Leni is an AI agent that works across 50 different medical fields to help doctors make better decisions and provide them with more streamlined information.

“Think of it as combining the knowledge of the best doctor with the capability of the best medical assistant into a 24/7, all-year-round AI agent,” explains Maximilian Waldmann, co-founder of ETERNO.

“There is a rising demand of patients and there’s a decreasing supply of physicians, and you just can’t get more hours out of the day. So you need to automate,” explains Waldmann.

In the digital age, many patients arrive at clinics having self-diagnosed using online information, while health data comes from smartphones, smartwatches, and files from other doctors.

“Our research shows that the practitioner has on average seven minutes to process all this data and come to a conclusion, which is an impossible job.”

“One of our agents summarises medical records—from handwritten notes to test results—in 30 seconds, giving doctors a holistic understanding of the patient.”

ETERNO has also developed agents to give doctors in private practice better financial insights.

"Doctors joke that the first time they get access to their data is when the tax advisor sends them their tax report," explains Waldmann.

He comes from a family of doctors but didn’t follow suit, choosing instead to become an entrepreneur.

“I’m the only one who didn’t make it into med school,” he jokes. “I think I was resistant because my dad wanted me to go.”

But after scaling his second company, he was ready to give something back.

"It was really important for us to deliver something that has societal value," he says.

There is a lot to do to get healthcare more digitised.

“The majority of small clinics are operating on very traditional on-premise IT services, and it can be very unintelligent,” explains Waldmann.

To better understand the challenges, ETERNO built three of its own clinics in Germany.

"Think of them a bit like a flagship store," explains Waldmann. "They are super-modern, and we built them to be able to reimagine care."

Leni is being tested in these clinics with plans to release it to the wider market this year. One of its jobs is to listen in to and learn from doctor-patient conversations, with consent. "We automatically transcribe and summarise that conversation and store it in the patient record," explains Waldmann.

From day one, ETERNO was determined to provide the highest levels of security and privacy for patient data.

Amazon Web Services (AWS) is central to this, helping to educate medical practitioners that the cloud is safe for sensitive medical data.

"You need a very strong and solid collaborator that allows you to break through the maze of complexity and innovate within healthcare, and that is something that AWS has been extremely supportive with," he says.

"Our entire infrastructure stack is running on AWS. The field of Large Language Models and generative AI is too fast and complex to navigate on your own. Everything we do to innovate outpatient care, from booking tools to AI agents to automated billing, is built on AWS."

One in three medical practitioners in Europe is above 60, and the majority are women. Many leave because they cannot get the right work-life balance.

Enabling doctors to work remotely and more flexibly is key to ETERNO 's mission, and it is encouraging people back into the profession.

"This has a huge impact on part-time workers, and we have doctors thankful that they are able to go back to work," explains Waldmann.

The future is looking bright for the start-up.

"Right now, we're competing strongly against existing healthcare providers. We've built three of the most modern clinics in the country. This is essentially about bringing healthcare to the next level."
