TUNAG's Remarkable Achievement

TUNAG, an employee experience (EX) platform developed by Stamen, has recently been honored with the 'High Performer' title in the 'Web In-House Newsletter Tool' category at the ITreview Grid Award 2026 Spring. This marks the 15th consecutive time TUNAG has received this prestigious recognition.

The ITreview Grid Award, organized by ITCloud, celebrates software and cloud services that have received positive user reviews on the ITreview platform. Awards are awarded based on factors such as customer satisfaction and brand recognition derived from extensive user feedback.

For TUNAG, receiving the 'High Performer' designation underscores its already high user satisfaction levels. It also indicates the product’s potential for gaining greater recognition in the marketplace as an innovative solution for corporate communication and employee engagement.

What is TUNAG?

TUNAG is an integrated platform designed to enhance organizational productivity and reduce turnover rates by promoting effective internal communication and information sharing. As of April 2026, over 1,400 companies and 1.5 million users have implemented TUNAG, demonstrating its broad appeal and effectiveness in workplace environments.

Unlike traditional engagement initiatives that primarily focus on surveys and diagnostics, TUNAG adopts a practice-oriented approach. It features tools that are closely tied to daily activities, such as an internal social network, recognition systems, and policy management. This design helps address organizational challenges through concrete actions and practices, making it especially useful for modern workplaces.
