Singapore · Participant Guide
Each team picks one track only.
Track 1 — Impact
Prove it with business value.
This is the traditional hackathon impact track. Your project is scored on whether it could create real value in the market.
- • The problem is real, and someone is willing to pay (or use it daily).
- • The product is polished enough that the demo itself sells it.
- • The craft, UX, and shipping-ness are visible from minute one.
- • AI-native, but the AI is in service of a human user — not the other way around.
Stack is free. Use Codex, use anything else. What you built matters more than what you built it with.
Think: AI-native SaaS, consumer apps, workflow automation, useful products people would actually pay for or open daily.
Track 2 — Harness
Prove it with technical depth.
Less about monetization, more about how well you tame and operate the agent. Like Oh My Codex, OpenClaw, gbrain, gstack, hermes — the harness wrapping the agent is itself the deliverable.
- • The agent runs long, runs autonomously, and finishes its job without babysitting.
- • Goal, termination, verification, and recovery are designed — not improvised.
- • Multi-agent orchestration, tool use, memory, and loop structure are deliberate.
- • A judge can read the harness and understand why it works, not just that it works.
Harness track must be integrated so it works with OpenAI Codex. MCP Server, Agents SDK, Direct API, /goal — integration method is free, but evaluation is anchored on Codex.
Think: autonomous coding agents, Codex-backed multi-agent systems, harnesses that wrap Codex with novel loop / memory / verification logic, meta-agents that improve themselves on Codex.

📹 Media Notice
This hackathon is being filmed by a professional video crew. If you prefer not to appear on camera, please let us know at check-in — we'll provide a sticker for your name badge so the crew knows to keep you out of frame.
Judges walk the floor and visit each team's table. ~3 minutes live demo + 1-2 minutes Q&A per team.
Show us what you have built. Please do not show us a presentation. We'll be checking to ensure your project was built entirely during the event; no previous work is allowed.
Scorecard
One card per judge per team.
Columns: Team name · Judge name · Live demo (0-4) · Creativity / Originality (0-3) · Impact potential (0-3)
Total: 10 points (Live demo 4 + Creativity 3 + Impact 3)
- • Live Demo (0-4) — How well does the team implement the core idea? Does it actually work live?
- • Creativity / Originality (0-3) — Has this been seen before? Does it tackle the track's problem in an original way?
- • Impact Potential (0-3) — Will this survive past the hackathon? How useful is it?
Tracks
Impact and Harness are awarded separately. The same scorecard is used, but for Harness, 'Live demo' evaluation includes Codex integration quality.
