Acalta

What Acalta does

Acalta GmbH is a German digital health company founded in 2021 and headquartered in Erlangen-Tennenlohe within the Medical Valley innovation cluster. The company develops a cloud-based digital health platform that connects patients and medical specialists through standardized, modular care plans, enabling asynchronous patient-provider communication, structured treatment documentation, and location-independent care coordination. Its product suite consists of four integrated components: the Acalta Health Platform (core infrastructure), the Patienta App (patient-facing mobile interface), Acalta Clinics (browser-based management dashboard for providers), and Versorgungspläne (configurable modular care plans containing questionnaires, reminders, information delivery, document exchange, diaries, and checklists, with vital sign integration under development).

Acalta serves German healthcare providers — primarily hospitals, medical practice networks (MVZs), oncology and radiotherapy departments, and university hospitals engaged in clinical research. The platform is fully eligible for funding under the KHZG (Krankenhauszukunftsgesetz / German Hospital Future Act), which subsidizes hospital digitization in patient portal, decision support, and cloud computing categories. Architecture is privacy-first: German server infrastructure, GDPR compliance, biometric authentication, and a de facto anonymity model that requires no traditional user accounts for patients. Deployment is available both as a cloud-hosted SaaS and as an on-premise install. Named customers include University Hospital Erlangen, Nordstrahl MVZ at Klinikum Nürnberg Nord, University Medical Center Göttingen, the RECUR registry (spanning ten German university hospitals for urinary stone research), and the BMBF-funded MIA-PROM research consortium with Charité Berlin and TU Berlin.

The business model is B2B SaaS subscription, sold via a direct sales team (CSO Frederik Kaul and Sales representative Monika Ammon) targeting enterprise healthcare providers in Germany. Revenue figures are not publicly disclosed. The company is venture-backed by the Fraunhofer Technologie-Transfer Fonds and has received non-dilutive support from EXIST, Start?Zuschuss!, Zollhof incubator, Existency, and Microsoft Startups. The founding team consists of three physicians (CEO Simon Winkler, CTO Dr. Nico Ploner, CSO Frederik Kaul) and CFO Eva Weber, all with medical training — a positioning the company leverages explicitly in its "by physicians, for physicians" brand.

Core offering

Acalta provides a cloud-based digital health platform that enables healthcare providers to extend treatment pathways beyond practice and clinic boundaries. The platform consists of Acalta Clinics (browser-based provider dashboard for patient enrollment, care plan administration, and data export), the Patienta mobile app (patient-facing interface for treatment status, health documentation, and asynchronous communication), and modular Care Plans (Versorgungspläne) that digitally map standardized clinical pathways using questionnaires, reminders, information delivery, diaries, and document exchange.

Product overview

Acalta offers a unified digital health platform consisting of three interconnected products: the Acalta Health Platform as the core infrastructure, the Patienta App as the patient-facing mobile interface, and Acalta Clinics as the browser-based management tool for healthcare providers. The system is built around modular Care Plans (Versorgungspläne) that digitally map standardized clinical pathways, enabling asynchronous patient-provider communication, treatment progress documentation, and location-independent care coordination. The platform is designed for healthcare providers including hospitals and clinics, with a focus on patient-centered care and highest data protection standards.
