DEINFO Internet Services

What DEINFO Internet Services does

DEINFO Internet Services is a privately held German IT services partnership (GbR) founded in 1997 and headquartered in Kusel, Rhineland-Palatinate, operating with 1–10 employees and serving SMBs, private consumers, and public institutions within approximately a 30 km radius. The firm operates a customized web hosting business on its own servers in German data centers, offering a 99.1% uptime guarantee, daily backups, and full-stack domain, email, and SSL services, layered with a broad portfolio of complementary products: S/MIME email encryption (GlobalSign), email archiving (SYNAXON), cloud-based VoIP telephony (ecotel cloud.phone), ESET endpoint security (as a 20+ year Gold Partner), fiber optic (FTTH/FTTB) installation, network infrastructure services, remote and on-site PC support, custom web application development (PHP/MySQL/HTML5/JavaScript/WordPress/Typo3/Joomla/Drupal), web design, and a refurbished hardware resale business built on business-grade leasing returns (Dell, Lenovo, Fujitsu, HP, Terra/Wortmann).

The underlying technology stack is deliberately self-hosted and sovereignty-oriented: proprietary servers in German data centers, Cloudflare CDN, self-hosted Matomo analytics, on-premise Jitsi Meet for video conferencing, Nextcloud for cloud storage, SolidWP for WordPress security, and S/MIME for email security. All data processing is GDPR-compliant (DSGVO), with order processing contracts (AVV) in place for third-party providers. The business model combines recurring subscription revenue (hosting, domains, S/MIME, ESET, email archiving, cloud telephony) with transactional revenue (refurbished hardware, professional services billed at 27.25 EUR per 15-minute increment for remote maintenance, fiber optic setup, and one-off IT support jobs).

Go-to-market is entirely direct and relationship-driven: phone (06381-994540), email, website contact form, and walk-in office visits at Schwebelstr. 14 in Kusel. There are no resellers, no paid digital advertising, and no self-serve or marketplace channels. The company is owned and operated by its two co-founders, Detlef Grimm and Peter Adamczyk, with no external investors, no subsidiaries, and no parent company. Customer concentration risk is high given the micro customer base within a single German district, but switching costs on hosted domains, email, and telephony provide some revenue stickiness.

Direct peers

• Strato AG: Major German hosting and email/S/MIME provider under United Internet, selling directly overlapping products (hosting, mail, domains, SSL) to SMBs across Germany.
• IONOS (1&1 IONOS): One of the largest web hosting and cloud infrastructure providers in Germany, competing directly with DEINFO's web hosting, domain registration, and email services - but at a vastly larger national scale.
• Hetzner Online: German hosting and data center operator offering shared hosting, servers, and managed infrastructure - directly comparable to DEINFO's proprietary-server, German-data-center hosting model.
• All-Inkl.com: German web hosting provider focused on shared hosting, domains, email, and small-business customers - the closest size-and-positioning analogue to DEINFO's SMB-focused hosting portfolio.

Broad incumbents

• Computacenter: European IT infrastructure services provider covering workplace, networking, security, and managed services - analogous corporate-IT capability set to DEINFO's PC service, networking, and security offerings but at enterprise scale.
• Bechtle AG: Largest German IT services and systems integrator with broad infrastructure, hardware, and managed services offerings - a vastly larger incumbent that competes on enterprise IT services dimensions DEINFO also addresses.
• Cancom SE: Major German managed IT services and cloud provider for SMB and enterprise customers - comparable service breadth (managed services, cloud, security) but multi-region and far larger.

Regional players

• NetCologne: Regional German telecom and IT-services operator in the Cologne/Rhineland area offering connectivity, hosting, and business IT services - a regional comparable but in a different geographic footprint than DEINFO's Kusel base.

Others

• Wortmann AG (Terra): German PC/notebook manufacturer whose Terra brand DEINFO resells alongside refurbished hardware - a key upstream channel partner rather than a competitor.
