We list more than 350,000 industrial suppliers. But we're unlike other directories. IndustryNet is built on accuracy, reliability, and real human research. Every supplier listing is researched and verified by our in-house team, supported by proprietary validation and quality-control processes — not scraped from outdated sources.

Our team of more than 80 professional data researchers reviews hundreds of sources to identify qualified industrial suppliers of all sizes. Each company is contacted multiple times per year to confirm its products, services, capabilities, certifications, and status. We maintain our listings through direct communication and continuous verification — not guesswork. We believe in accuracy, completeness, and quality over quantity.

Many directories list only suppliers who pay or who manually create their own profiles. Others rely entirely on suppliers to update their own information. IndustryNet takes a different approach: our data team proactively researches, updates, and maintains every qualified listing to ensure buyers always have access to the most accurate and complete industrial directory available.

We have been helping industrial professionals find reliable suppliers for more than 100 years. IndustryNet is powered by MNI, the nation's most trusted source of industrial information. Since 1912, MNI has refined the art of discovering and verifying U.S. industrial companies. Today, that expertise powers a modern platform that connects industrial buyers and suppliers across the country.
