Welcome to MNI
People-powered industrial data since 1912.
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 unmatched detail and consistency.
Who We Are
More Than a Century of Industrial Leadership
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 the most reliable, accurate, and comprehensive insight into the American industry.
Major media outlets, government agencies, and industry organizations rely on our research
as a definitive benchmark.
A Dedicated Team of Research Professionals
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.
Nearly a Half Million Industrial Companies
Our database covers nearly a half million U.S. manufacturers, suppliers, distributors, fabricators,
warehouses, industrial service providers, and related operations. We don't stop at basic firmographics —
we document capabilities, employment and sales figures, certifications, markets served, facility functions,
and other crucial details you won't find in scraped or automated datasets.
Nearly a Million Executive Contacts
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
Human-Verified, Not Scraped
Scraping and automation can't 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.
Unmatched Detail and Depth
- 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
Accuracy You Can Trust
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.
Ethical and Transparent Data Practices
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
Direct Phone Verification
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.
Email-Based Updates
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.
CASS, DPV, and NCOA Validation
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.
Smart Verification Technologies
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.
Copy Editing and Quality Control
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.
Continuous Real-Time Updates
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.
