Ditto raises €7.6M for patient-side AI summaries of medical appointments

At a glance:

• Dutch health-tech startup Ditto raises €7.6M led by Heal Capital to expand its AI-powered medical appointment summaries to Germany, UK, and Spain
• The mobile app generates plain-language summaries of consultations, helping patients remember more than the typical 20-40% retention rate
• With 100,000 users in the Netherlands and 4.7-star ratings, Ditto operates free for patients through partnerships with insurers and healthcare institutions

The funding round

Ditto, an Amsterdam-based health-tech building AI-generated summaries of medical appointments for patients, has raised €7.6m, the company announced on Monday. The round is led by Heal Capital with participation from Rubio Impact Ventures. Earlier backer Chris Oomen, chair of Optiverder, has also participated in this latest funding round. This financial injection will support the company's expansion into Germany, the UK, and Spain this year, as well as continued development of its consumer product.

The funding comes as Ditto has demonstrated significant traction in its home market. The company launched in the Netherlands with the support of the national Patient Federation, initially targeting 10,000 downloads in six months. However, Ditto reports that it hit that figure in under two weeks and is now approaching 100,000 users in the Netherlands, with 4.7-star ratings on both the App Store and Google Play. The company recently won the Dutch Healthcare Innovation Award, further validating its approach to addressing a critical gap in healthcare communication.

The problem Ditto solves

Ditto was founded by CEO Tobias Lensing alongside co-founders Bart Voorn and Merlijn van Breugel after Lensing accompanied a friend with stage-4 bile-duct cancer to an oncology appointment and realized the two had walked away with materially different understandings of what the doctor said. This experience highlighted a fundamental challenge in healthcare: patients typically remember only 20% to 40% of what is communicated in a medical consultation.

This knowledge gap has significant consequences for patient outcomes. When patients don't fully understand their diagnosis, treatment plan, or follow-up instructions, they may struggle to adhere to medical recommendations, leading to poorer health outcomes and increased healthcare costs. Traditional approaches to addressing this issue have focused on providing written materials or allowing patients to record consultations, but these methods don't actively help patients process and retain the critical information shared during appointments.

How Ditto's AI works

The product is a mobile app that records the consultation with the patient's consent and generates a structured, plain-language summary that the patient can revisit, share with family, and use to prepare for follow-up appointments. Unlike many AI healthcare solutions that focus on clinical workflows, Ditto's approach centers on the patient experience. The app uses advanced natural language processing to identify key information from conversations, organize it into digestible sections, and present it in clear, accessible language.

The position runs counter to the prevailing direction of AI in healthcare, which has focused primarily on clinician-side tools for note-taking, triage, and chart-completion. Ditto argues that the lower-cost, higher-leverage opportunity is on the patient side. By empowering patients with better information, the company aims to improve adherence to treatment plans, reduce confusion, and ultimately lead to better health outcomes. This patient-centric approach represents a significant shift in how AI is being applied to healthcare challenges.

Business model and expansion

Ditto is free for patients, with the company funded through partnerships with insurers, patient organizations, and healthcare institutions. The business model is based on the premise that the same summary that informs a patient also reduces follow-up calls, repeat explanations, and missed appointments on the clinician side. This creates value for both patients and healthcare providers, making the service sustainable without direct patient fees.

The company plans to use its new funding to expand beyond its successful Netherlands market. Ditto will enter Germany, the UK, and Spain this year, adapting its platform to meet the specific regulatory requirements and healthcare systems of each country. The company says it will go deeper into the patient journey, helping users prepare for upcoming appointments based on their consultation history rather than only summarizing past ones. This evolution represents a more comprehensive approach to patient support throughout the healthcare continuum.

Investor perspective

Heal Capital is one of Europe's most active health-tech investors, bringing significant expertise and network connections to Ditto's growth trajectory. Rubio Impact Ventures, which also participated in the round, brings an impact mandate aimed at populations the press release describes as those "the system already overlooks." This focus on underserved populations aligns with Ditto's mission to improve healthcare communication for all patients, regardless of their background or technical proficiency.

Earlier backer Chris Oomen, chair of Optiverder, has also participated in this funding round, continuing his support for the company. Oomen's involvement suggests confidence in Ditto's long-term vision and potential to transform healthcare communication. The diverse investor group brings not just capital but also strategic guidance and connections that will be valuable as Ditto expands across Europe.

Regulatory compliance and future outlook

Ditto is governed under the EU AI Act and publishes its compliance posture on its website. This proactive approach to regulation demonstrates the company's commitment to ethical AI development and patient privacy. As AI applications in healthcare continue to evolve, regulatory frameworks will play an increasingly important role in shaping how these technologies are developed and deployed.

Looking ahead, Ditto's leadership believes there's significant potential to expand the platform's capabilities beyond simple summarization. The company aims to develop more sophisticated features that help patients navigate complex healthcare systems, track their health metrics over time, and better communicate with their care teams. By focusing on the patient experience and leveraging AI to bridge communication gaps, Ditto is positioning itself at the forefront of a new wave of health-tech innovation that puts patients at the center of their care journey.
