Mindoo
6DC has invested in Mindoo, a platform of configurable AI agents that support clinical and administrative workflows in hospitals and medical practices.
AI Agents
Mindoo sits at the intersection of two major new software trends.
The first is the emergence of Artificial Intelligence (AI) agents. These are software systems that autonomously interpret data, make decisions, and take action to achieve defined goals. Unlike traditional automation, AI agents can reason, retain memory, learn from feedback, and adapt to context, allowing them to execute complex, multi-step processes.
This represents a fundamental change in the role of software, from tools that made people more productive, to systems that deliver results autonomously.
Voice as an interface
The second trend is the emergence of voice as a technology interface.
Speaking is the most natural, fast, and low-friction way for humans to interact. It is certainly more intuitive than typing or navigating software menus.
Recent advances in speech recognition, real-time processing, and large language models have dramatically improved the accuracy, contextual understanding, and responsiveness of voice interactions. Speaking to software now feels fluent and intelligent.
Importantly, insights from Conveo, another 6DC investment using voice as an interface, show that users often engage more openly when interacting with software. In human conversations, people withhold information to protect social dynamics or avoid awkwardness, whereas voice interactions with software elicit greater candour.
Rescuing a stretched healthcare system
Autonomous software is a welcome evolution in industries facing structural labour shortages. Healthcare is a prime example, with the World Health Organisation (WHO) estimating that Europe will require an additional 4.1 million healthcare workers by 2030.
An ageing population is placing increasing pressure on the healthcare system. Worker shortages are already leading to delayed diagnostics, longer waiting times for specialist consultations, reduced overall care, and an increase in medical errors.
Finding an additional 4.1 million doctors and nurses over the next 4 years is unrealistic, let alone expanding healthcare budgets to afford this. Solutions that increase system capacity without additional human labour are much needed. Against this backdrop, it is unsurprising that hospitals are showing strong interest in the potential of artificial intelligence and AI agents.
Mindoo
Mindoo provides a suite of specialised, configurable AI agents designed to support clinical and administrative workflows in hospitals and medical practices.
One example is Mindoo’s Pre-Visit Agent, which collects relevant patient information prior to a doctor consultation. The Agent conducts an intake conversation via voice (or text, if preferred), either at home or upon arrival at the hospital.
During this interaction, the AI agent evaluates the patient’s symptoms and reviews their medical history. Unlike traditional intake forms with static questionnaires, the conversation is dynamic and adaptive: the agent genuinely interacts with the patient and adjusts its questions in real time based on the patient’s responses. Mindoo operates in 57 languages, significantly reducing language barriers in care delivery. After the intake conversation, the agent automatically generates structured patient records for the clinician.
The Pre-Visit Agent is already being deployed in hospital emergency departments, where it frees up nursing staff previously responsible for intake. By offloading this task and providing better records to doctors, Mindoo increases the efficiency of the hospital staff, allowing them to focus on things that only humans can do and increasing overall treatment capacity without adding headcount.
Mindoo as a platform
Mindoo is an Agentic Platform. The ambition is to provide the full suite of AI agents required to operate a hospital or healthcare practise efficiently. In addition to the Pre-Visit Agent, Mindoo has already developed several other agents, including:
Post-Visit Agents, which follow up with patients at home after a hospital visit or surgery to monitor recovery.
Scribe Agents, which generate clinical notes and letters for doctors in seconds.
Booking Agents, which automatically schedule appointments, confirm them to reduce no-shows, and fill cancelled slots, thereby maximising treatment capacity.
Custom Agents, which can be tailored for specific workflows. Simply describe what you need, and the agent follows.
The fact that Mindoo has a platform strategy is crucial to our investment case. System reliability is paramount for hospitals as failures in IT can have life-critical consequences. Therefore, hospitals actively limit the number of technology vendors they work with. They prefer deep, trusted partnerships with a selective number of partners over a fragmented array of point solutions.
This dynamic also creates a strong incentive for speed in the go-to-market. Once a vendor is embedded and proves reliability and value, it is typically retained for the long-term. Hence, we have pushed Mindoo for a larger funding round at Seed.
Founders
Gauthier Willemse (CEO, Co-founder) graduated Magna Cum Laude in Medicine from the University of Leuven and worked for four years as a general surgeon at UZ Leuven. He subsequently completed a Master’s in Public Health at Harvard, where he caught the entrepreneurial bug. Upon returning to Belgium, Gauthier founded Rotayo, a platform addressing healthcare staff shortages by streamlining visa and licensing processes for international medical professionals. He also served as Belgium’s Deputy Chief Medical Officer, an impressive achievement at just 30 years old. With the emergence of artificial intelligence. Gauthier saw an opportunity to address structural issues in healthcare with technology, and he founded Mindoo in 2025.
Bart Lens (CTO, Co-founder) previously worked as senior software engineer at DataCamp, before joining Conveo (another 6DC company) as the founding engineer. He spent 1.5 years at Conveo and joined when the team moved to San Francisco for the Y combinator program, before giving in to the itch to start his own company. Conveo’ CEO Dieter De Mesmaeker recruited Bart after working with him at DataCamp and considers him exceptional.
Both Gauthier and Bart are genuinely impressive, with deep expertise and complementary skill. The ambition is bold but credible: to build infrastructure so fundamental that the next generation of doctors will wonder how healthcare ever functioned before Mindoo.
Traction
We’re investing at an early stage, which is appropriate given that the technology to deliver a smoothly functioning Mindoo simply did not exist two years ago. Founded in 2025, Mindoo has, in less than a year, delivered an initial version of the tech and completed pilots with several leading hospitals.
Pilots have far exceeded customer expectations and every pilot hospital is now in negotiations for a full-scale rollout. During our customer reference calls, hospitals consistently highlighted both the quality of the technology built by Bart, and the benefit of Gauthier deeply understanding hospital operations, having worked inside the system himself.
International expansion is already underway. Mindoo has completed its first pilot in Germany, which is also moving to a hospital-wide rollout. Additional pilots are being scheduled for different hospitals in Germany. Across different countries, there is now a pilot waiting list that will keep the team busy until the summer.
Delivering this level of traction in under a year is testament to both the execution capability of the founding team, and the urgency of the problem that Mindoo is addressing. Medical practices have a need for these solutions and are moving quickly to adopt them.
Opportunity
Hospital software spending is split between multi-million central IT investments and independent departmental budgets for specialised tools., both are significant budgets. Crucially, AI agent costs are not just weighed against IT allocations; they are benchmarked against significantly larger staffing budgets, reflecting their potential to augment the workforce. Hospitals have substantial capital to invest in solutions like Mindoo.
Because hospitals actively compare notes, and prefer to limit the number of IT vendors, it is a sector where we often see 90% market shares for software providers on a regional basis. This dynamic makes for an atypical venture opportunity in the sense that we expect Mindoo to gain very high market shares in a small number of geographies, rather than a small market share globally.
We believe that Mindoo will capture most of the Belgian hospital market, a meaningful share of Germany, and potentially The Netherlands. Combined, these markets represent approximately 2,500 hospitals and 80,000 healthcare practises, a revenue opportunity well into the hundreds of millions annually.
