iO's rise stems from focused investment in a dedicated Contentstack competence centre. We built deep platform expertise and earned significant credibility through high-profile projects where Contentstack's composable digital experience platform emerged as the winning choice after rigorous selection processes.

Elite Partner status is Contentstack's highest tier, reserved for partners demonstrating exceptional technical expertise, proven results with organisations, and strategic platform knowledge. iO joins a select group of global agencies qualified to deliver complex composable architecture projects.

"iO consistently champions composable thinking and guides customers with clarity and confidence. Their growing expertise and the strength of our collaboration have made a real impact for enterprises navigating large‑scale digital transformation. Reaching Elite status reflects the momentum we’ve built together and the value iO brings to our shared customers. And we look forward to how else we can work together as the market continues to evolve.” - Preseetha Pettigrew, Global VP of Partnerships, Contentstack

Composable architecture for ambitious brands

As Elite Partner, iO helps businesses unlock the full potential of headless CMS and composable architecture. The agency guides clients through platform selection, migration, integration, and optimization—ensuring technology choices align with business goals, not vendor hype.

"Achieving Elite Partner status reflects our commitment to mastering the platforms that matter most to the organisations we work with," says Jochem Molenaar, Service Line Director Technology at iO. "Contentstack's composable approach bridges the gap between ambitious content strategies and the technical reality of delivering them at scale."

The partnership strengthens iO's position as a leading composable DXP partner in Europe, working with over 1,500 brands across marketing, platforms, and content.
