IONOS is a cloud services and web hosting provider founded in 1988 as 1&1, operating for over three decades before evolving into its current form following its combination with ProfitBricks in 2018. Headquartered in Europe and part of the United Internet group, the company serves more than 6 million customers across Europe and North America, with over 4,000 employees spread across 70 countries.
The company builds and operates its own data centers in Europe and the United States, rather than reselling third-party infrastructure. Its product portfolio spans web hosting, email services, cloud computing, AI platforms, and enterprise-level container orchestration. This vertical integration of infrastructure underpins IONOS's emphasis on data security, privacy, and reliability as distinguishing characteristics of its offering.
Its primary market is small and medium-sized businesses, for whom it positions itself as a digital infrastructure partner. Notably, every customer is assigned a dedicated personal consultant to advise on products and business needs - an unusual service model in a sector that typically operates at scale with minimal human contact. Products are designed to scale from a startup's first website through to enterprise container orchestration deployments.
The engineering organisation works across cloud infrastructure, container orchestration, security and privacy, AI platforms, and data center construction and operations. IONOS describes its working culture as combining the operational scale of an established infrastructure business with the agility of a technology company.
