What Zone35 does

Zone35 GmbH & Co. KG is a Berlin-based, owner-managed digital agency founded in 1999 that supplies software products and digital services to organizations in the German healthcare and welfare (Dritter Sektor) sectors. Its core proprietary platforms are assisto, a modular online consultation software for psychosocial counseling offering text/video chat, mail consultation, and appointment management; beranet, an online consultation platform for secure and anonymous counseling via mail, chat, and forums; and e-coaches, a personalized online health coaching platform for prevention programs delivered over multiple weeks. Alongside these products, Zone35 delivers professional services including website relaunches, e-magazine development, CMS/CRM/E-commerce implementations, and cross-media concepts, with a stated emphasis on accessibility (barrier-free design) and mobile optimization. The technology stack is built on PHP and open-source foundations, notably TYPO3 CMS, with mobile-optimized web front-ends for consultation interfaces.

The company operates through a hybrid of recurring SaaS subscriptions for assisto and beranet (offered as white-label solutions to counseling centers and social institutions) and project-based digital consulting engagements. Its named customers comprise German BKK statutory health insurers (BKK Stadt Augsburg, BKK Mobil Oil, BKK Akzo Nobel), welfare associations (Der PARITÄTISCHE Wohlfahrtsverband Hamburg, Deutsche Rheuma-Liga Bundesverband), and patient-advocacy non-profits (Bayerische Krebsgesellschaft). Zone35 claims to operate the most widely used online consultation platform in Germany (beranet.de) and to be the largest provider in Germany for psychosocial online consultation software (assisto). Distribution is direct (website contact forms, email, demo requests) with white-label/OEM licensing as a secondary channel; the firm maintains dedicated product landing pages (assisto.online, beranet.de, e-coaches.de) and a content blog (beratungsrauschen.de).

Zone35 is structured as a GmbH & Co. KG with sole managing director Maximilian Ort responsible for strategy, product management, and business development, supported by Stefanie Rostin in project coordination and HR. The firm reports headcount ranging from 18 (main page) to 35 (shortfacts) digital media specialists across sources and is bootstrapped, with no disclosed institutional investors, funding rounds, or parent entity. Geographic operations are confined to Germany, although markets-served listing references the broader DACH region.
