What Join does

Join GmbH is a privately held German IT consulting and solutions company headquartered in Magdeburg with a second office in Eisenach, formed in 2018 from the merger of B-S-S Business Software Solutions GmbH and Lintra Solutions GmbH (both founded 1999). The company employs 70+ experts and serves 750+ customers across 3,900+ projects globally, operating as a Microsoft Solutions Partner (Legacy Gold status) and ISO/IEC 27001:2022-certified integrator focused on the Microsoft 365 and Azure ecosystem. Its primary customer base is mid-market and large enterprises, supplemented by public administration, tourism organizations, and corporate legal departments.

The company combines professional services (strategic IT consulting, workshops, custom software development, and integration) with a portfolio of proprietary products. Core products include LEDOX365 Legal Suite (a contract and matter management platform operating as a Private Cloud Application within the customer's M365 tenant with an embedded AI assistant), CompanyGPT (a self-hosted, LLM-agnostic enterprise AI platform), RathausGPT (an open-source sovereign AI solution for German public administration with F13 reference architecture compatibility), and the KI-Telefonassistent (an autonomous AI phone agent for 24/7 call handling). Technology integrations span SAP, Salesforce, DocuSign, Adobe Sign, SharePoint, Teams, Twilio, and ElevenLabs.

Join's revenue model blends time-and-materials consulting, fixed-price project work, recurring software licensing/support, and implementation services for its proprietary products. Go-to-market is predominantly direct enterprise field sales with a consultative motion, supplemented by distribution through the Microsoft partner network and tourism industry associations. The company is owner-managed by Managing Director Christian Wittrich with no disclosed external venture or private equity investment, consistent with a traditional German Mittelstand IT firm.
