Mathieu Marteau

Founder of DeaLynx, web developer

• Price tracking
• Fake discounts
• French e-commerce
• Web development

Mathieu builds and runs DeaLynx on his own, in France. He wrote the engine that records the prices of more than a thousand products every day on Amazon, Fnac, Darty, Cdiscount and Boulanger, and the usual-price method that tells real discounts from fake ones.

Every comparison and guide relies on data actually collected by DeaLynx, not estimates. Publication and update dates are shown on every page, and the barometer figures are recomputed weekly.
