u+i interact

u+i interact is a digital agency with 85+ experts, headquartered in Bielefeld, Germany. Founded in 2007, we design and build structured, high-performance digital platforms – with a strong focus on B2B clients in manufacturing, logistics, and professional services, and an equally sharp eye for ambitious B2C projects. Our interdisciplinary teams combine digital strategy, UX/UI design, content architecture, and full-stack development. A defining part of our DNA: our in-house Usability Lab, where we test and validate digital experiences with real users – ensuring that every platform we build not only performs technically, but converts and engages. We help clients replace legacy systems with scalable content operations on Sanity – delivered fast, built to last. Part of the Hagedorn Group.

From strategy to go-live – and beyond. We offer end-to-end services around structured content platforms built on Sanity: content architecture and modeling, Sanity implementation, UX/UI design, custom frontend development, and seamless integrations with ERP, CRM, and third-party systems. A core part of our approach is our in-house Usability Lab, where we validate digital experiences with real users before and after launch. We also support clients long-term with ongoing platform management, editorial training, and SEO-driven content strategies.

We work with mid-market companies ready to move from legacy CMS systems to a structured, flexible content platform on Sanity. Our core expertise lies in B2B – manufacturing, logistics, and professional services – where content complexity, multi-stakeholder workflows, and long-term platform thinking matter most. At the same time, we love working with B2C brands that bring bold visions and high content demands: campaign platforms, brand presences, and digital experiences that need to perform at scale. What sets us apart: before we build, we understand. Our Usability Lab gives clients real user insights early in the process – reducing risk and increasing the impact of every Sanity implementation.
