AltriScore is a French business information service that helps users assess the reliability of companies in France. It calculates an index from 0 to 100 using official public data, including INSEE’s Sirene register, BODACC announcements, INPI/RNE records and the European VIES VAT system. The site presents scores across five bands, from “Very low” to “Excellent,” to make results easier to interpret.

Each company profile identifies the sources used and when the data was recorded. AltriScore says its calculation methodology is public and versioned, with no undisclosed criteria and no option to purchase a higher score. Users can search for a business by name or registration number, browse companies by activity or department, and check a website’s compliance. The service also provides customer review listings. Companies may request a free review of their profile or challenge an index, with a response promised within 14 days. By combining dated official records with an explainable scoring approach, AltriScore offers a structured way to explore company information and evaluate business reliability.
