COMEUP 2025: Why EventCAT Was Chosen for AI Simultaneous Interpretation at an International Exhibition
Held in December 2025 at COEX in Seoul, COMEUP 2025 brought together startups, investors, policymakers, and industry leaders from around the world. As one of Asia’s leading global startup conferences, COMEUP is designed to connect Korean innovation with international markets - making multilingual communication a core requirement rather than a secondary feature.
To support this global audience, EventCAT was selected as the official AI simultaneous interpretation solution, enabling real-time multilingual access across the entire event.
AI Simultaneous Interpretation Across Multiple Stages, in Real Time
COMEUP 2025 ran for three consecutive days with five stages operating simultaneously. Keynotes, panel discussions, and live Q&A sessions unfolded in parallel, requiring a solution that could scale without disrupting the flow of the event.
EventCAT delivered real-time AI simultaneous interpretation and live captions across all stages without interpreter booths or additional hardware. Attendees simply accessed translations via QR codes on their own devices, allowing speakers to present naturally while audiences followed in their preferred language.
This approach significantly reduced operational complexity while ensuring that every session remained accessible to international participants.
Live Captions for Global Online Audiences
In addition to on-site interpretation, COMEUP 2025 placed strong emphasis on digital reach. Major sessions on the main stage were streamed live on YouTube, with real-time captions powered by EventCAT embedded into the broadcast.
This allowed global online viewers to follow presentations and discussions as they happened, rather than relying on post-event summaries. The response from online audiences was notably positive, with viewers highlighting how real-time captions made the content easier to follow and more engaging - especially for non-native speakers.
Real-Time Subtitles as a Global Promotion Experience
One of the most talked-about activations during COMEUP 2025 was a new initiative designed to support startups’ global visibility. Participating companies recorded short on-site pitches, which were instantly enhanced with real-time AI-generated multilingual subtitles.
These subtitled videos enabled startups to present their ideas clearly to international investors, partners, and media - without additional production steps. The initiative demonstrated how AI simultaneous interpretation and live subtitles can extend beyond the conference hall, becoming a powerful tool for global storytelling.
The on-site reaction was enthusiastic. Startups, visitors, and international guests gathered to watch the subtitled pitch videos, recognizing them as immediately usable global communication assets.
A Practical Example of AI Simultaneous Interpretation at Global Events
COMEUP 2025 illustrated how AI simultaneous interpretation is now being applied at scale in real-world international conferences:
- Multiple stages running concurrently
- Real-time multilingual access for on-site attendees
- Live captions for global online audiences
- Subtitled video content created instantly for international outreach
Rather than slowing conversations down, AI-powered interpretation allowed sessions to move faster, discussions to flow more naturally, and global participants to stay fully engaged.
Setting a New Baseline for International Conferences
At COMEUP 2025, AI simultaneous interpretation was not presented as an experimental technology - it functioned as core event infrastructure. By enabling seamless communication across languages, platforms, and audiences, EventCAT helped transform a complex international exhibition into a truly global experience.
The event demonstrated a clear shift in how major conferences approach accessibility and engagement: real-time AI interpretation and captions are no longer optional enhancements, but essential tools for global-scale events.
