The Problem
Sound familiar?
Marketplaces lose buyer trust when bad sellers aren't caught until after damage is done
Manual seller vetting doesn't scale and creates inconsistent standards
Existing fraud tools focus on buyers, not the sellers who create systematic harm

Frequently Asked Questions
How is Trust Score trained and kept up to date?
The ML model is retrained monthly on aggregated marketplace outcome data (fulfilled vs. disputed orders). Your marketplace can optionally feed outcome labels to fine-tune accuracy on your specific seller population.
Does this work for C2C (consumer-to-consumer) marketplaces?
Yes. The signal set is designed for both professional and casual sellers. Weights adjust automatically based on seller volume tier.
