Kammann Rossi

What Kammann Rossi does

Kammann Rossi GmbH is a privately held, owner-managed corporate communication agency headquartered in Cologne with a second office in Munich, founded in 1972 and operating across the DACH region. The firm serves enterprise and mid-market clients with full-service agency work spanning corporate reporting (annual, integrated, ESG/CSRD and sustainability reports), content marketing (magazines, reports, campaigns in digital and print), internal and change communications, and design services. Named clients include ARAG, OLB (Oldenburger Landesbank), DEUFOL, Lidl Schweiz, Clariant, Continental, Deutsche Bahn, REWE, GTAI, Henkel, Schaeffler, Liebherr, MANN+HUMMEL, NRW.BANK and the IHK Köln, supported by long-running multi-year reporting mandates (e.g., ARAG 2001–2023, OLB ongoing, DEUFOL since 2018).

In 2023 Kammann Rossi launched AssistantOS, a proprietary AI platform positioned as Germany's first agency-built AI infrastructure. AssistantOS aggregates third-party large language models (OpenAI GPT, Anthropic Claude, Perplexity) and image models (Midjourney, Stable Diffusion, Recraft) into role-specific AI assistants — Carl (Copywriter), Cora (Consultant), Dave (Designer) and Wanda (Wildcard) — extended in 2024 by modular Skillboxes. The platform is hosted on Microsoft Azure in European data centers under DSGVO-compliant agreements. Revenue is generated through three streams: project-based agency services, AI transformation and KI-Enabling consulting retainers, and SaaS subscriptions (Pro Assistant from €249/month, Enabling Package from €768/month, Custom Assistants from €512/month). Complementary products include CoffeeFM (social podcast app) and a 2023 Metaverse portfolio for AR/VR/NFT communications.

The company is led by Managing Partners Carsten Rossi and Viola Kirchhoefer and Managing Director Dr. Christian Fill (joined 2020), supported by a ~20-person team of long-tenured editorial, design and AI specialists based in Cologne and Munich. Kammann Rossi has accumulated extensive industry recognition — including 43 awards in 2020, #2 in the Lout Chartbreaker Ranking 2024/25, and wins across ARC, iF, LACP, Red Dot, ADC, FOX, Mercury, Galaxy and Stevie competitions — and maintains sponsorship and jury roles at the INKOMETA and ARC Awards.
