This week we’re celebrating the first winner of our inaugural Demo Day and sharing what the Builder Circle can look forward to next!
The Short Version
New blog is live on why AI-generated documents need independent verification beyond surface-level polish.
Demo Day crowned its first winner: Joshua Mwangi’s DuelLegends showed how Proof of Quality can power fair, skill-based competition.
Builder Circle returns next week with Lukas Grapentine sharing product updates and hosting a live AMA.
New Blog: Why AI Documents Need Independent Verification
AI can generate polished documents in seconds, but verifying them is much harder.
The core problem
Citations may be incorrect
Quotes may be fabricated
Claims may mix real and false information
What the blog covers
Why hallucinations are hardest to detect when they look professional
Why mixed real and fake sources are especially dangerous
How Proof of Quality verifies documents using structured consensus and audit trails
Our First Real Product Data Pilot
We’ve completed our first pilot using real production data, and we’re now applying the results.
Key question
Can Proof of Quality evaluate AI work where there is no ground truth?
If you missed it, the full pilot write-up is on our blog: How Proof of Quality Caught All Nine Errors in an Automotive Training Data Trial

The best of many great submissions.
Demo Day Has Its First Champion
Our first Demo Day is complete, and it delivered exactly what we hoped: builders applying Proof of Quality in real ways.
Congratulations to Joshua Mwangi and his project DuelLegends!
DuelLegends is a skill-based arena where players stake into escrow and winners are decided using AI review with an independent consensus and Proof of Quality scoring.
Thanks to everyone who participated!
