What COSYNUS GmbH does
COSYNUS GmbH is a privately held, owner-managed German software company headquartered in Darmstadt that has built enterprise communication and mobility software since its 1993 founding. Its portfolio centers on three product lines: the COSYNUS Corporate Communication Server (CCS), a unified messaging server integrating email, fax, SMS, voice, and social media into business applications; the COSYNUS Mobile Device Server (MDS), a centralized mobile device management platform supporting BlackBerry OS, iOS, Android, and Windows Phone with push synchronization, encrypted transfer, and remote wipe; and SmartMeeting, a cloud-based service for cross-company appointment coordination. Around these, the company packages a hybrid mail product (ePorto), custom native and Progressive Web App development on React/Docker, an open-source public-health interface (IRIS connect co-developed with Björn Steiger Stiftung), and a broad set of utility modules (Mail2Fax, PDFFax, COSYNUSconnect, etc.). Technology is delivered on-premise as server software with documented integrations into SAP, Baan ERP, Tobit.Software David, BlackBerry Enterprise Mobility Suite, and FIO2, and is positioned as DS-GVO/GDPR-compliant.
The company serves small and medium enterprises as well as large enterprises across all industries, with disclosed customer logos spanning manufacturing (Pepperl+Fuchs, Ralf Bohle/Schwalbe, BIEBER+MARBURG, ENGESER), financial services (Sparkasse Darmstadt), government (HEAG Holding), and media (Kai Pflaume), claiming over 1,000 companies and 2,000+ MDS deployments across DACH and Italy plus 50,000+ daily mobile-app users. Revenue is generated from software licensing, subscription cloud services, multi-tier technical support, and project-based custom app development, with no public pricing. Distribution combines direct enterprise sales with a three-tier certified partner program (Business, Solution, Qualified) of 50 partners across Germany, Austria, Switzerland, and Italy, supplemented by an own download portal and Apple/Google app-store publishing. The company has no disclosed external funding, no subsidiaries, no M&A history, and no patent or award filings in the available record, operating as a classic, bootstrapped German Mittelstand software house.

COSYNUS GmbH competitors and assessment
Company assessmentEmerging players
- Sinch: Cloud communications platform specializing in messaging (SMS, WhatsApp, RCS), voice, and email APIs. Overlaps with COSYNUS on the SMS/voice/email unification layer and SAP/CRM integration use cases, but delivers via APIs rather than on-premise servers.
- NetSfere: Enterprise messaging and communication platform focused on secure, compliant messaging for regulated industries. Overlaps with COSYNUS on the unified messaging/secure communications proposition, particularly in German/European enterprise and public-sector contexts.
Broad incumbents
- Avaya: Global incumbent in enterprise unified communications and contact center, including on-premise and cloud UC. Competes with COSYNUS for the same enterprise telephony and unified messaging workloads, but at a far larger scale and with a broader product portfolio.
- Atos (Unify OpenScape): European incumbent providing enterprise UC (OpenScape) and communications services to large and mid-market organizations. Directly comparable to COSYNUS on unified messaging/voice, but operates at a much larger scale and a broader portfolio across managed services and infrastructure.
- RingCentral: Cloud UCaaS leader offering voice, messaging, video, and contact center. Competes with COSYNUS on unified communications, but with a pure-cloud delivery model versus COSYNUS's on-premise-first stack.
- 8x8: Global UCaaS and contact-center-as-a-service provider competing for the same enterprise communications wallet. Similar overlap on messaging, voice, and integration, though 8x8 is significantly larger and cloud-native.
- Ivanti (MobileIron): Enterprise mobility management and unified endpoint management vendor. Competes with COSYNUS MDS for centralized device management across iOS, Android, and other platforms, with a larger scale and broader endpoint footprint.
- Mitel: Provider of enterprise UC, VoIP, and cloud communications. Overlaps with COSYNUS on unified messaging and multi-channel enterprise communications, especially in European mid-market and SME deployments.
Direct peers
- BlackBerry: Provider of BlackBerry Enterprise Mobility Suite for MDM and secure mobile communications, an active technology partner of COSYNUS. Directly comparable on the MDS side — both target regulated, security-conscious enterprises with multi-OS device fleets.
- Tobit.Software (David): German unified messaging vendor behind the 'David' platform, which is a core integration partner for COSYNUS CCS and MDS. They share the same DACH Mittelstand customer base, the same fax/email/SMS/voice-centric UC proposition, and are frequently deployed together (e.g., X-Leasing, Schwalbe).
