Jahn

What Jahn does

Jahn, legally Klaus Jahn Markt- und Mediaberatung GmbH and trading as Werbeagentur Jahn, is a full-service advertising agency founded in 1967 and headquartered at the Streits-Haus on Jungfernstieg in Hamburg, Germany. The firm operates as a private Gesellschaft mit beschränkter Haftung (GmbH) with 11-50 employees and is led by Managing Director Michaela Stein-Zenker, who has 30 years of tenure with the company. There is no parent company, no external funding, and no public listing.

The agency's service portfolio spans six interconnected pillars: strategic consulting (Beratung), media planning and advisory (Mediaplanung/Medienberatung), creative services including copywriting and design (Text/Gestaltung), multimedia production (Produktion), recruitment advertising (Personalmarketing), and channel-specific advertising across print, outdoor, digital, social media, and broadcast media. The technology stack is traditional rather than proprietary; no APIs, SDKs, AI capabilities, or platform products are disclosed. Competitive positioning is built on independence from publishers and job boards, enabling neutral cross-media consulting, and on five decades of continuous operation under the same trade name at a prestigious Hamburg address.

Commercially, Jahn generates revenue through project-based and multi-year retainer engagements with German businesses ranging from small firms to large enterprises, with some European cross-border reach. Pricing is fully custom with no published tiers. Go-to-market is direct sales-led, anchored by phone (040 343361), email ([email protected]), and personal consultation at the Hamburg headquarters. No named customer logos, revenue figures, or awards are disclosed, and there are no subsidiaries, acquisitions, partnerships, or external investors recorded in the source material.
