What Dr. Flex does

Dr. Flex GmbH is a Berlin-based SaaS company founded in 2015 that provides an AI-powered patient communication and appointment management platform for medical and dental practices in Germany. The platform serves over 14,100 practices and processes approximately 4.5 million appointments annually. Its core offering combines an online appointment booking system with VoiceAI, a proprietary AI telephone assistant, supplemented by a modular suite of add-on products including Smart Messaging reminders (€0.12 per notification), an automated Recall-Service for DMP and preventive-care follow-ups, a digital waitlist for cancellation recovery, a patient self-service portal, and an SEO-optimized public practice discovery portal. Distribution follows a hybrid model: direct sales and personalized demos for mid-market practices, self-serve onboarding with a 30-second setup for smaller practices, and channel referrals from web agencies and PVS (Practice Management System) vendors.

The technical foundation is the proprietary PVS-Connector, which provides real-time bidirectional synchronization with 27+ German Practice Management Systems including medatixx, CGM (Z1, M1 PRO, ALBIS, MEDISTAR, CHREMASOFT via PRAXISTIMER), Dampsoft DS-Win, INDAMED Medical Office, charly by solutio, ivoris, Evident, Dentport, Doc Cirrus inSuite, and Quincy by Frey. VoiceAI processes patient audio locally without transferring to third-party cloud services, transcribes speech into structured tickets, and autonomously resolves roughly 74% of incoming phone calls while reducing practice phone volume by up to 90%. The platform is hosted exclusively in Germany on BSI C5-attested and ISO 27001-certified cloud infrastructure with full GDPR/DSGVO compliance, and was named Stiftung Warentest Test Winner (Note 1.6) in January 2021.

Dr. Flex monetizes primarily through tiered monthly SaaS subscriptions — Starter at €39/month on a pay-per-use basis and Flat at €99/month with unlimited usage — with no setup fees, no contract duration, and monthly cancellation, plus usage-based fees for Smart Messaging notifications. The company appears bootstrapped with no disclosed external funding rounds, no parent company, and no M&A history, operating with a headcount of 11–50 employees from its Berlin base.

• Smart Messaging Automated appointment reminder and patient communication module sending SMS and email reminders 24h and 2h before appointments, plus preparation instructions per appointment type. Supports up to 8 languages. Pay-per-use at €0.12 per notification.
• Dr. Flex Portal Public patient-facing portal with SEO-optimized practice profile pages. Extends practice visibility beyond the practice website so patients searching for a practice can discover and book via the portal. Included in the Combi tariff at no additional cost.
• Booking Widget 24/7 appointment booking calendar embedded on the practice website. Customizable to practice branding; works without patient registration. Links can be placed on the practice website, Google Business Profile, newsletters, or social media.
• Digitale Nachrückerliste (Digital Waitlist) Automatic waitlist management: when a patient cancels, the system identifies matching waiting patients by practitioner, appointment type, insurance status, and availability, and sends an SMS or email offer. First patient to confirm gets the appointment, which syncs back to the PVS in real time.
• Booking Manager Central task and event manager for all practice inquiries and tickets generated by VoiceAI. Practice staff can view, prioritize, and process incoming patient requests from a unified dashboard.
• WordPress Plugin WordPress integration that allows practices to embed the Dr. Flex Booking Widget on their WordPress website in minutes without a developer, providing all booking widget functions.
• Praxis-Konfigurator (Practice Configurator) Backend configuration tool for fine-grained control of booking logic: individual appointment types with duration, practitioner and room resource logic, pre-booking questions, specialist consultation settings, DMP structures (Diabetes, KHK, Asthma, COPD), HzV-specific appointment types, and recall rules. Changes are self-managed without support tickets.
• Recall-Service Automated follow-up appointment management triggering personalized SMS or email reminders for DMP follow-up appointments, preventive screenings, vaccinations per STIKO recommendations, and recall appointments. Patients select a slot directly from the reminder; the appointment syncs to the PVS in real time.
• Termin-Infobereich (Appointment Info Area) Patient self-service portal accessed via a one-time link in confirmation or reminder emails/SMS. Patients can view appointment details, reschedule, cancel, or complete digital anamnesis forms without creating an account.

Direct peers

• Doctolib: Europe's leading online appointment-booking and telehealth platform with dominant German market presence. Doctolib competes head-on with Dr. Flex in practice scheduling, patient communication, and video consultation for medical and dental practices.
• Jameda: German doctor directory and online appointment-booking platform (part of Docplanner Group). Jameda directly overlaps with Dr. Flex in patient-side appointment discovery and practice-side scheduling for German physicians and dentists.
• Docplanner: Parent group of Jameda and other healthcare-booking marketplaces across Europe and Latin America. Comparable SaaS-plus-marketplace model targeting SMB practices, making it a strategic peer to Dr. Flex.
• Samedi: Berlin-based online appointment and patient-communication platform for hospitals, medical practices, and MVZs in Germany. Directly comparable in target customer, geography, and core booking/communication functionality.
• Termed: Germany-focused online appointment-booking platform for medical and dental practices. Closely overlaps with Dr. Flex in target customer, product scope (online booking, reminders), and German SMB-practice distribution.
• arzttermine.de: German online appointment-portal marketplace where patients can book appointments with doctors and dentists. Comparable patient-side discovery and practice-side scheduling proposition to Dr. Flex.

Broad incumbents

• CompuGroup Medical: Largest European provider of practice management systems and healthcare software, and a key integration partner of Dr. Flex (Z1, Z1.PRO, ALBIS, MEDISTAR, CHREMASOFT, M1 PRO via PRAXISTIMER). CGM could expand into the patient-experience/booking layer Dr. Flex occupies.
• medatixx: Major German PVS vendor with a large installed base of medical practices. Listed as a core integration partner of Dr. Flex and a potential competitor or preferred channel partner depending on strategy.

Regional players

• Doctena: European online appointment-booking platform active in Benelux, Germany, and other markets. Comparable SaaS model targeting medical and dental practices, though its core strength lies in non-German geographies.

Emerging players

• Zava (formerly DrEd): European direct-to-patient digital health platform offering online consultations, prescriptions, and referrals. Adjacent rather than directly competing in SMB-practice scheduling, but a useful comparator for AI-enabled patient communication in regulated European healthcare.
