Today, when various digital technologies such as AI and IoT are drastically changing our society, economy, and lifestyle. You could say that we live in an era of digital overlapping, where "digital encompasses everything. The evolution of digital technology is accelerating at an unstoppable pace. In such an environment, companies are forced to redesign themselves to fit the digital age (digital transformation). All actions will be converted into data in some form or another and will be utilized in an online competitive principle that transcends physical limitations. beBit believes that the O2O (Online to Offline) concept, which considers online and offline as separate entities and tries to connect them, has already become obsolete, and that we are moving into the OMO (Online Merges Offline) era, which considers digital and real as one platform. The scalability of technology increases the convenience of people and improves the value of their experience. In other words, under the OMO concept, all businesses will shift from being product-based to being experience-based and will become more like social infrastructure. In other words, companies need to redefine "products, services, and promotions" as "experiences that blend into the lives of users regardless of whether they are digital or real". By supporting "experience design," we strive to create a "better society" for both companies and consumers.
