The first protocol where reviews make you money.
We solved e-commerce's $787B fake review problem by making honest reviews more profitable than fake ones.
The problem
30% of online reviews are fake today, costing consumers and businesses $787B annually. 54% of consumers won't buy a product if they suspect fake reviews. Current solutions — AI detection, verified purchase badges, moderation teams — all fail because they're playing defense against an offense with unlimited resources.
You can't solve fake reviews with better detection. You need to make honest reviews more profitable than fake ones. That's what UMP does — a revenue-sharing review system that rewards users who accurately predict marketplace success, solving the fake review problem through economic incentives rather than identity verification.

UMP Labs is founded by experienced builders with years of blockchain infrastructure, smart contract development, and forensics expertise.
Nick and Barabazs met in the crypto trenches — recovering stolen funds, auditing smart contracts, and building infrastructure that needed to work under adversarial conditions. They saw the same problem from different angles: online commerce is broken because trust systems are broken.
Today, UMP Labs is building the protocols that make peer-to-peer commerce trustworthy, private, and accessible to everyone. The review system is the first product — aligning economic incentives so that honest reviews are the most profitable strategy.
