Hadiryuk is an Indonesian event platform for people who want to create, share, discover, and attend events focused on education, personal development, and inspiring ideas. It serves both event organizers and participants, bringing event listings and ticket transactions together in one place. Organizers can create an event and share it with prospective attendees, while visitors can browse upcoming events, review details, select tickets or merchandise, enter their information, and proceed to payment. Users can also access their tickets through the platform.

Hadiryuk features a varied calendar, including conferences, competitions, open houses, festivals, workshops, and certification events. Listings range from webinars and professional development training to mathematics competitions and English-language assessments, with events held online or at venues. The site also provides guidance on how to transact and create an event, along with support information, refund details, and terms and conditions. Through these services, Hadiryuk offers a practical destination for finding events and managing the steps involved in participating. The platform is powered by PT Teknologi Karya Sejahtera.
