MNI is the nation's trusted source for industrial information and data. Since 1912, we have been dedicated to documenting, verifying, and maintaining complete, in-depth profiles on U.S. manufacturers, suppliers, and industrial service providers. Our mission is to provide accurate, ethical, and human-verified industrial data that helps businesses grow, innovate, and compete with exceptional detail and consistency.
Who We Are
Since 1912, MNI has been the trusted authority for industrial information. Our print directories have evolved into modern digital platforms, but our mission remains the same: to provide reliable, accurate, and comprehensive insight into U.S. industry. Major media outlets, government agencies, and industry organizations rely on our research as a definitive benchmark.
Behind every profile is a team of skilled researchers, fact-checkers, copy editors, analysts, and developers. We interview companies directly, validate information across multiple sources, and apply industry expertise to ensure each record is complete, accurate, and trustworthy. Every company profile is built by real people who understand industrial operations, supply chains, and manufacturing.
Our database covers nearly a half million U.S. manufacturers, suppliers, distributors, fabricators, warehouses, industrial service providers, and related operations. We go beyond basic firmographics, documenting capabilities, employment and sales figures, certifications, markets served, facility functions, and other crucial details not typically found in scraped or automated datasets.
We maintain direct-contact details for executives across ownership, leadership, operations, engineering, procurement, HR, plant management, and other key roles. Executive data includes names, titles, and functions served. Wherever available, we include personal email addresses, giving you powerful visibility into the individuals who make or influence purchasing decisions.
Why Our Data Is Different
Scraping and automation cannot capture real operational insight. Our profiles are built through direct outreach, verified public sources, and human analysis — not bots, guesswork, or machine-generated data. This approach delivers dramatically higher accuracy, especially for privately held, family-owned, mid-sized, and hard-to-reach industrial companies.
- Corporate hierarchy (HQ, branches, subsidiaries)
- Competitors identified through real research
- Verified SIC/NAICS classifications and business descriptions
- Products manufactured, services provided, and markets served
- Capabilities, products and services offered, and certifications
- Executive names, titles, and direct contact information
- Operational details including employee count and annual sales
Industrial companies evolve constantly — relocating, expanding, changing ownership, shifting production, or retooling operations. Our continuous verification process and multilayered quality checks combat data decay and ensure our records remain far more accurate than automated or scraped alternatives. While no data provider can guarantee 100% accuracy, we work tirelessly to deliver the most reliable industrial data available.
We never scrape personal inboxes, harvest private browser data, or pull from questionable sources. All data is collected ethically through direct communication, verified public information, and industry-standard research methods. Companies trust our approach, making them more willing to provide accurate updates.
How We Collect and Verify Data
Our researchers speak directly with company staff to confirm executive names, titles, product lines, capabilities, certifications, facility roles, markets served, employment levels, and other critical operational details. These conversations often uncover nuances that scraped sources simply cannot detect.
Companies are contacted multiple times per year by email to review and update their information. Direct input from the business helps us maintain exceptional accuracy while capturing leadership changes, expansions, rebranding, new capabilities, and other updates as they occur.
Every address is verified using national postal standards and relocation tracking, including weekly CASS certification and Delivery Point Validation (DPV) and quarterly National Change of Address (NCOA) processing. This ensures deliverability, reduces returned mail, and keeps contact information consistent across all locations associated with a company.
Our proprietary systems flag irregularities in phone numbers, email formats, industry classifications, executive changes, and facility details. Emails, websites, and phone numbers are verified regularly through automated processes. Any anomalies are reviewed by our research team, ensuring that outdated data is removed immediately and questionable data never makes it into the record.
Every record passes through multiple human checkpoints — editing, validation, normalization, consistency checks, and quality assurance reviews. Each profile must meet our rigorous standards for clarity, consistency, accuracy, completeness, and style before it is added or updated in our digital products.
Industrial activity moves fast — mergers, expansions, facility closures, equipment upgrades, hiring shifts, and leadership changes. We update records year-round using verified sources, direct company outreach, industry news, government filings, and dozens of other proprietary real-time indicators.
