What ESB does

ESB IT-Services GmbH is a privately held, founder-managed IT system house headquartered in Hersbruck, Bavaria, approximately 30 km east of Nuremberg. Founded in 1990 by Frank Büttner as EDV-Systeme Büttner, rebranded to ESB IT-Services e. K. in 2008, and reincorporated as a GmbH in 2025, the company has operated continuously for over 30 years serving small and medium-sized businesses and select Mittelstand clients across the Nürnberger Land region. The firm maintains a team of over 10 employees plus apprentices and has relocated to progressively larger premises five times since 2011, most recently moving to a significantly expanded headquarters at Nürnberger-Str. 3 in 2023.

The company's service portfolio is organized around full-service managed IT for SMBs, including automated 24/7 server and network monitoring, patch management, centralized antivirus (ESET), Secumail-based spam filtering with 95% reduction, MailStore-compliant mail archiving under DSGVO and GoBD, NovaStor-based backup and disaster recovery, penetration testing, WLAN coverage planning, and infrastructure consulting. Adjacent offerings include Microsoft 365 deployment, Auerswald and NFON telephony systems, Toshiba managed print services, AQUADO server procurement with up to 60-month on-site warranty, NUKI smart access control, and LUPUS-based alarm and video surveillance. ESB operates as a manufacturer-independent reseller, integrating best-of-breed third-party products rather than developing proprietary software.

Commercially, ESB runs a sales-led, consultation-based go-to-market targeting SMB and mid-market clients through direct relationships and website-driven inbound inquiries. Revenue is generated through a mix of recurring monthly managed service subscriptions, hardware sales and leasing (multi-year contracts), Microsoft 365 seat-based services, project consulting, and managed print. Pricing is quote-based and not publicly disclosed. The company maintains no external institutional investors, no subsidiaries, and no acquisitions, with all operations concentrated in a single Bavarian office and no disclosed expansion into additional German states or international markets.

Highly comparable business model to ESB (managed services, consulting, infrastructure, hardware), serving the same SMB/mid-market segments but at national and international scale.

• msg systems AG: msg is a major German IT consulting and services firm with strong presence in insurance, banking, and public sector. Comparable to ESB in offering IT consulting, infrastructure, and managed services, though focused on larger enterprise clients and industry verticals rather than horizontal SMB.
