OpenAI × Start2 × Zendesk Hackathon
Build with Codex. Ship in one night. Win real prizes.
OpenAI, Start2, and Zendesk are teaming up for a hands-on build night at the Hanwha AI Center.
Bring your laptop, team up, and ship a working prototype in a single focused evening — powered by OpenAI's Codex and a lineup of 2-3 standout APAC dev tool companies.
This isn't about shipping a finished product. It's about building something real and showing it off live by the end of the night.
Best builds win.
