connpass - The IT meetup platform for building connections Overview & Contact Data

Connpass is a Japanese web platform for organizing, publishing, and promoting IT meetups and technical events. It helps developers, engineers, open-source contributors, designers, product teams, and community organizers create event pages, invite participants, and manage groups around technology topics. The service is commonly used for public tech talks, workshops, hackathons, user groups, and company-led developer events, making it a practical tool for people who want to build a local or remote audience around a specific subject. The platform supports event creation with details such as title, schedule, venue, capacity, and publish date, then shares the event through search, group pages, and social channels including Twitter. Organizers can track upcoming events, recent presenters, and public event listings, while attendees can browse by date, topic, or community. Because listings often include date and time, presenter names, and public event status, users can compare options before registering for an event. Paid event support gives hosts a way to run ticketed sessions, while group features help maintain ongoing communities rather than one-off gatherings. What makes Connpass notable is its focus on IT and engineering communities, particularly in Japan, where it has become a familiar channel for meeting other developers, sharing technical knowledge, and discovering niche meetups. It reduces the administrative work of event promotion by combining scheduling, registration, discovery, and community management in one place. For attendees, it makes it easier to find upcoming public events and follow presenters or groups. For organizers, it offers a straightforward way to publish an event, attract participants, and build a repeatable community around technology topics.
