The Team That Brings Events Alive
zzzarit Inc. builds and delivers interactive software for events.
What We Do
Kiosk contents, QR access systems, photo booths, wish trees, mini games — we build event software from scratch and deliver it ready to run. Hardware and software are considered together, so nothing breaks on the day.
What We Build
We build the interactive software events need — in-house.
Interactive saju readings from a guest's birth date and time.
A participatory piece guests fill together with their wishes.
Shoot on-site and print or share instantly.
Custom games that turn waiting time into fun.
Pre-registration, on-site check-in, and issuance — the whole entry flow.
Time-slot booking, multi-booth ops, KakaoTalk alerts, and interpreter dispatch — all in one.
With you from planning to teardown
One team, responsible from start to finish.
We design the content around the event's goals and flow.
We develop the software in-house.
We bring in the gear and install and test on-site.
We run it with you on event day.
We handle gear collection when it's over.
No outsourcing. Fast iteration and full customization.
Designed for real event conditions — lighting, networks, crowds.
From planning to on-site setup to teardown.
Why ‘zzzarit’
It started when the AR service ‘kkkAR’ met IT.
Type ‘ㅋㅋㅋ’ with the Korean/English key toggled and it turns into ‘zzz’. Add IT and you get zzzarit — read aloud, ‘zzarit (짜릿).’ AR meets IT to spark the moment.
The logo is a lightning bolt drawn from the vowels ㅏ and ㅣ in ‘짜릿’ — the electric moment that wakes an event up.
Team
Two co-CEOs who plan and build it themselves.
Ran a video production studio and an event agency, and led DX at a mid-size event agency. Rooted in video production and on-site event operations.
A developer who ran his own software studio. Designs and builds the products and systems himself.
What We've Done
Every event we ran and every solution we delivered — in one place.
