IONOS Group

What IONOS Group does

IONOS Group SE (ticker: IOS) is a publicly listed European IT services group headquartered in Montabaur, Germany, that operates as Europe's leading SMB digitalization partner and cloud enabler. The company was founded in 1988 and was spun off from United Internet AG, with Ralph Dommermuth (founder of United Internet) serving as Chairman of the Supervisory Board. The Management Board comprises Achim Weiß, Patrik Heider, and Dr. Jens-Christian Reich. The group employs between 1,001 and 5,000 staff across offices in Germany, Austria, the UK, Spain, Romania, and the Philippines, and serves approximately 6.81 million customers across 17 markets in Europe and North America (as of March 31, 2026), with around 22 million registered domains and an NPS above 34.

The business is organized around two product pillars. The first, Web Presence & Productivity, bundles domain registration, web hosting, website builders, do-it-yourself solutions, e-commerce tools, online marketing, and the Nextcloud Office productivity suite. The second, Cloud Solutions, delivers enterprise-grade IaaS and PaaS via the IONOS Public Cloud (with SDN and NFV capabilities), supplemented by Defense Products (DDoS protection, WAF, Zero Trust, CDN). The technology stack includes 30 company-operated data centers, Kubernetes-based container orchestration, Linux server infrastructure, an AI-driven customer care platform, and an emerging AI Agent platform for SMBs. The platform is delivered through ten retained sub-brands — IONOS, STRATO, InterNetX, arsys, fasthosts, home.pl, sedo, united-domains, world4you, and we22 — each addressing a regional or functional niche.

Revenue is generated primarily through subscription-based recurring contracts across both B2C and B2B channels. Distribution combines a self-serve e-commerce platform (product-led growth) with a customer-service-driven sales motion (telesales and retention teams), supported by performance marketing (PPC, AI-automated SEA/social/display), content, email, and a customer referral program. Primary customer segments are SMBs and individual consumers, with a secondary enterprise segment targeted through cloud infrastructure offerings. Mid-term financial targets are approximately 10% CAGR revenue growth and roughly 40% adjusted EBITDA margin over four to five years.
