The business expo is a regular event organized by Atma Jaya Business Incubator, aimed at fostering innovation and collaboration among entrepreneurs and business leaders. This event serves as a platform for showcasing new business ideas, networking with industry professionals, and exploring potential partnerships. Each year, the expo features businesses run by Atma Jaya students from various industrial backgrounds, including food and beverage, souvenirs, and more.
In 2024, the third business expo was held in collaboration with Universiti Teknologi Malaysia (UTM). UTM and Atma Jaya have partnered on various occasions, such as lecturing sessions and product innovation competitions, which were participated in by UTM students. This collaboration not only enriched the academic and practical experiences of the students but also strengthened the relationship between the two institutions.
