What global office GmbH does

global office GmbH is a German telephone answering and call management service provider headquartered in Heiligenroth (Montabaur district), Germany, founded in 2000 and operating as a private GmbH (HRB 21326, Amtsgericht Montabaur). The company delivers inbound call management ("Erreichbarkeitsservice") and outbound telephone marketing ("Telefonmarketing") for small and mid-sized businesses, with a roster of named customers spanning automotive dealerships (AVP Autoland, Autohaus Dresden), hospitality (Hotel Sacher Vienna), events (Messe München), legal practices, public sector bodies, and energy utilities.

Its service architecture combines 450+ trained human telephone agents branded as "Telefonengel" with AI voicebot technology introduced in 2024, enabling 24/7 handling of routine inquiries while routing complex, empathy-requiring conversations to human agents. The platform supports API, XML, and email-based message delivery into customer systems, and the company has begun productizing vertical-specific bots such as the Hospitality Bot showcased at Intergastra Stuttgart in February 2026.

global office distributes its service through a franchise network of 55+ locations across Germany, Austria, and Namibia, with 33 direct employees supporting the central organization. Revenue is generated via subscription-based recurring contracts; managing director Erik Krömer leads the company. In September 2024, Deutsche Telekom featured global office as an AI reference customer at its Digital X trade show, providing third-party validation of the hybrid service model.

• Cognigy: Aachen-based enterprise AI agent platform for customer service automation via voice and chat. Directly comparable to global office's AI voicebot layer; both target enterprise CX automation in DACH and increasingly compete for the same conversational-AI budgets.
• D+S GmbH (D&S Gruppe): Hamburg-based CX and market research BPO with large contact-center operations in Germany. Comparable inbound/outbound telephone services, multi-vertical coverage, and German market focus; overlaps with global office's core service portfolio.

• arvato (Bertelsmann): German-headquartered BPO and customer service provider within the Bertelsmann group. Operates large contact centers for enterprise and public-sector clients in DACH; directly overlaps with global office's vertical mix including automotive and government.
