StartupTribunal runs monthly 30-day build competitions where founders build real companies with your APIs — and AI agents analyze every integration, security gap, and documentation failure at file:line precision.
VibeJudge scans every submitted GitHub repo for your API usage. Which endpoints developers reached for first, where implementations broke, what your docs are missing. File:line citations verified against actual code.
Worth $5,000–15,000 from a research firm
Between submission and results — the 48-hour window when every developer remembers everything — we deploy your custom survey. Fresh opinions, specific friction points, honest NPS from builders who just spent 30 days with your API.
50–200 qualified developer responses
Founders earn bonus judging points for publishing Medium articles about their build. We track every article and tweet referencing your product via Medium RSS and Twitter/X API. Content that ranks on Google for 12–24 months.
Tracked via Medium RSS + Twitter/X API
Your API is recommended to founders building in your vertical on Day 1 of a 30-day build — the only moment they are actively choosing their tech stack. Not after launch. Not at a conference. Now.
Day 1 of 30-day build window
Entry fees for capped founder spots are covered in your name. Every founder who competes sees: 'Entry sponsored by [Company].' Emotional association at the moment of gratitude, not passive banner awareness.
40–200 sponsored spots per tier
Your contribution to the prize pool is credited in the winner announcement — shared by the winner to their entire network across 14 countries. The announcement that every participant reads.
