Idana

Idana AG, formerly known as Tomes GmbH, operates a digital platform designed to streamline patient intake and documentation for medical practices and clinics. Founded in 2016 in Freiburg, Germany, by a team including doctors Lilian Rettegi and Lucas Spohn, the company addresses the increasing time pressures within the healthcare system. The founders, rooted in the medical field, aimed to create a solution that enhances the efficiency of routine processes, allowing physicians to focus more on direct patient interaction. The company transitioned from a GmbH to an AG (Aktiengesellschaft) in July 2023 to facilitate investment from other medical professionals and stakeholders, aligning with its "By Doctors for Doctors" philosophy.

The firm's core product, Idana, is a cloud-based SaaS platform that digitizes patient onboarding, medical history collection (anamnesis), and the signing of consent forms. It serves medical practices and clinics, enabling them to send digital questionnaires to patients before their appointments. Patients can complete these forms on any device, from home or in the waiting room via a tablet or QR code. The collected data, which can include everything from symptoms to administrative information, is then automatically structured and integrated into the practice's existing management software. This pre-visit data collection provides doctors with a comprehensive overview of the patient's condition, optimizing the consultation itself. Revenue is generated through a subscription-based model, with a satisfaction guarantee that allows new customers to claim a refund within the first three months if the product does not meet expectations.

The Idana platform is designed for seamless integration with various practice management systems via standards like GDT, HL7, and JSON, and it can automatically file reports in the patient's digital record. A key feature is its extensive library of over 400 customizable medical questionnaires and forms, which can be adapted using a built-in editor. The system also highlights critical patient answers and calculates clinical scores, providing actionable insights for the physician. For enhanced legal and medical quality, Idana collaborates with Thieme Compliance to offer over 2,000 legally vetted informational sheets in multiple languages. The company has secured funding from investors including Start-up BW and Universal Capital, and in March 2025, it closed a multi-million Euro Series A financing round to expand its technical team and customer support.
