What inlingua Frankfurt does

inlingua Frankfurt is a private language school operating as inlingua Sprachschule Frankfurt GmbH & Co. KG, established in 1968 and headquartered on Kaiserstraße near Willy-Brandt-Platz in Frankfurt am Main. The school is part of the global inlingua network (260+ schools across 30+ countries) and delivers language instruction in German, English, French, Spanish, and Italian through daytime classes, evening courses, private lessons, intensive crash programs, online formats, and language travel. It serves both private individuals (students, expats, professionals, exam candidates) and corporate clients, including named accounts such as Lufthansa, Accenture, ING DiBa, Deutsche Bundesbank, Air Liquide, Stada, Chemetall, Ferchau, DFB, and LSG Sky Chefs.

The core technology is the proprietary inlingua communicative learning method, a standardized pedagogy emphasizing active language use, complemented by a corporate onboarding platform for client-side training management, free online placement tests, and telc-aligned diagnostic and mock-exam preparation tools. As an authorized telc test center, inlingua Frankfurt administers official B1, B2, and C1 University German certification exams on-site, integrating exam administration with course delivery under a single roof.

The business model combines per-participant course fees (group and private lessons), corporate full-service contract revenue (customized curricula, onboarding platform, attendance monitoring, on-site or blended delivery), one-time telc exam fees (€189–€199 per candidate), and language travel commissions through the inlingua network. Go-to-market is sales-led with enterprise field sales (managed by Managing Director Thomas Sonntag) targeting large accounts, supported by online placement tests, content marketing, and direct consultation. The asset-light operating model relies on approximately 19 core employees and 120+ contracted language trainers to serve 6,000+ participants annually across 300+ corporate clients.
