Patient 21

What Patient 21 does

Patient21 (Patient21 SE) is a Berlin-based healthtech company founded in 2020 by serial entrepreneurs Christopher Muhr (former COO of Auto1 Group) and Nicolas Hantzsch (exits include Veganz, HometoGo, and Groupon) that operates an integrated dental care platform combining a network of 56+ owned dental clinics across Germany with a proprietary software suite. The company serves two primary segments: individual dental patients, reached through the Dental21-branded clinic network with online booking, short wait times, and standardized modern facilities; and independent dental practice owners, targeted through a structured 6-step integration/succession program and standalone software products. The core technology stack comprises five interconnected software modules — Availy (online booking), Claire (practice management), Medlog (described as an AI-based dental assistant), Happy (review management), and Medpress (practice websites) — alongside a Crocodile Health digital learning platform for employee training. Underlying the clinical operation is a hub-and-spoke architecture in which software developed for internal use is also licensed externally, creating a software business layered on top of the clinic roll-up. Internationally, the group has established Patient21 EOOD in Bulgaria as a regional entity.

The business generates revenue across three streams: direct clinic operations from treatment fees paid by patients (the dominant stream); subscription/SaaS revenue from external dental practices licensing the Availy, Claire, Medlog, Happy, and Medpress software products; and managed services revenue from practice integration, succession transactions, billing, QM (quality management), inventory, and marketing support. The company reports 100,000+ patient visits in 2022, 501–1,000 employees, and a subsidiary structure of more than 20 wholly-owned German MVZ (Medizinisches Versorgungszentrum) entities plus Dental21 GmbH and Dentalab21 GmbH, reflecting an aggressive roll-up strategy. Pricing for clinical services is quote-based and not publicly disclosed; software pricing varies by practice size with custom quotes. Cumulative funding disclosed across rounds totals approximately $188M, with a $76M Series C (May 2023) led by Pitango VC and a $32M debt facility from IPF Partners in the same month, alongside prior rounds backed by Target Global, Piton Capital, PICO Venture Partners, Eight Roads, Bertelsmann Investments, and Artian Investments.

The go-to-market is multi-modal: direct-to-consumer for clinic bookings (leveraging Google reviews, Jameda, and SEO), sales-led B2B targeting practice owners for integration and succession, and product-led growth for the external software suite. Markus Boser serves as Chair of the Supervisory Board, and the company has been recognized as a Kununu Top Company in both 2024 and 2025 for employer branding. No public revenue figures are disclosed; pricing is opaque; and the AI positioning rests primarily on the Medlog product and the use of digital X-ray/intraoral scanning infrastructure across clinics rather than on proprietary models or research artifacts.
