About
Built by one engineer and a weekly pipeline
SoldSignal exists because resale prices online are mostly asking prices, single-market, or behind a paywall. This site puts real sales from several marketplaces side by side, for free.
How it runs
Every week a pipeline runs public web-data collectors (Apify Actors written by me), cleans and matches the results, computes the statistics and rebuilds this site. The whole run costs less than a cup of coffee per month. The same collectors are public on the Apify Store, and a sample dataset is on Hugging Face and GitHub.
Who built it
I'm Malek Oweis, an AI automation engineer. I build data pipelines, scrapers, MCP servers and AI-agent workflows that run on their own.
