Polish health platform Doctor.One secures €4 million to expand its asynchronous care model for chronic patients

Warsaw-based HealthTech startup Doctor.One has raised a €4 million Seed round to support expansion into Germany, Spain, and the UK, building on its early commercial success in Poland and demand for chronic care solutions that move beyond episodic or telemedicine models.
The round was led by YZR Capital, with participation from Impact Ventures and existing investors.
“We aim to become the go-to digital companion for healthcare professionals managing chronic patients – keeping them connected, informed, and supported between in-person visits,” said Maciej Malenda, the Co-founder and CEO of Doctor.One.
Founded in 2021, Doctor.One is a chronic care platform that aims to empower healthcare professionals to stay connected with their patients through continuous, asynchronous communication. By transforming care into a relationship-driven experience beyond the visit, the company looks to help improve engagement, boost adherence, and ensure that no chronic patient feels alone in their health journey.
Rather than replacing the physician-patient connection, the platform says they strengthen it – empowering healthcare professionals to support their patients between hospital appointments or clinic visits without overloading their schedules.
The company is currently running programmes with pharmaceutical companies Novartis, Novo Nordisk, Merck and AstraZeneca, helping its partners improve adherence, patient engagement, and long-term outcomes through structured digital care paths and human touch.
With almost half a million of microinteractions facilitated across therapeutic areas such as obesity, oncology, neurology, and endocrinology, the platform has proven both clinically valuable and psychologically resonant.
“We are strong believers in exceptional teams fixing crucial problems on a large scale with innovative solutions,” said Markus Feuerecker, the Co-founder and Managing Partner from YZR Capital. “In Doctor.One we found such a team that stands out with their asynchronous care model and already proven success in tackling key issues in care pathways using scalable technology while providing clear value to patients, providers and pharma groups at the same time.”
Doctor.One is also collaborating with healthcare providers across Europe, including a flagship partnership with Uniwersyteckie Centrum Kliniczne (UCK) in Gdańsk as part of the EU-funded Amber Project. This initiative, uniting partners from five countries, is transforming cancer care through proactive, home-based support that’s relational rather than transactional.
Still in 2025, the company is on the way to increase its revenue eightfold and grow its team in Sales, Product, AI, and Growth to support the expansion with its focus on relational, continuous care.
“Doctor One is making doctor-patient direct communication more accessible and taking it to a new level, with the aim of providing more effective and more human treatment,” added Gergő Iváncsics from Impact Ventures.
Operating in full compliance with GDPR and ISO standards , the team is now preparing to scale its platform across Germany, Spain and UK —Europe’s largest healthcare markets.
