Ostertag Solutions

What Ostertag Solutions does

Ostertag DeTeWe GmbH, operating under the short brand 'OD,' is a privately held German IT services company headquartered in Germany with multi-country DACH coverage (Germany, Austria, Switzerland). The company delivers digital workplace, unified communications and collaboration (UCC), enterprise networking, security, multi-carrier connectivity, and managed services to mid-market and enterprise customers. Its portfolio is structured around four pillars — Connected Work (Modern Work / UC), Network & Security, OD Carrier (a Multi-Carrier Concept providing multi-provider architecture for high-availability connectivity), and (Managed) Services — and is sold alongside proprietary sub-brand YoUC Connect, a Cloud PBX offering.

Revenue is generated through three streams: professional IT services (consulting, implementation, and support), recurring managed services (operation, monitoring, and ongoing support of customer infrastructure), and product sales and licensing of third-party UC platforms (Microsoft 365, Mitel, Zoom) and the YoUC Connect PBX. The go-to-market is enterprise-direct via website contact funnels supplemented by a partner/reseller channel for major vendor platforms, with no public pricing — all engagements are quote-based on annual terms. The company serves four primary verticals — healthcare, automotive and industrial manufacturing, public administration, and financial services and trade — and holds ISO-related customer satisfaction recognition, with strategic partnerships spanning Microsoft, Mitel, Zoom, and (recently announced February 2026) a flagship partnership with Zoom Communications to target the German enterprise collaboration market.
