About SupplierDiversity.com
The definitive resource for diverse business owners pursuing certification and contracting.
Most diverse business owners spend weeks figuring out what certifications they need, where to apply, and which corporations actually buy from certified suppliers. The information is out there. It's just spread across a dozen certifying bodies, fifty state agencies, and a federal contracting portal that wasn't written for newcomers. We put it in one place.

Who's behind this
Built by Will Moss & Mario Bailey.
Will Moss
Co-founder
Will Moss co-founded SupplierDiversity.com with Mario Bailey on the premise that the supplier diversity ecosystem deserves the same product polish as a personal-finance or e-commerce site. Diverse business owners shouldn't have to be procurement experts to find the right certification, the right corporate program, or the right federal opportunity for their business.
Will leads platform, data infrastructure, and product. That includes the federal spending pipeline (sourced from USASpending.gov), the certifying body and corporate program directories, the eligibility and matching tools, the buyer-supplier marketplace, and CertifyAll, the unified certification submission service.
He focuses on making the site the kind of resource diverse business owners actually use, not just bookmark.
Mario Bailey
Co-founder & Editor-in-Chief
Mario Bailey founded SupplierDiversity.com to fix a problem he kept seeing first-hand: diverse business owners spending dozens of hours navigating fragmented certification rules, scattered corporate program directories, and federal contracting jargon — only to give up before reaching a single qualified contract.
The premise of SupplierDiversity.com is straightforward: pull every certification path, every corporate supplier diversity program, every state agency, and every federal contract opportunity into one place — with verified data, plain-language guides, and tools that do real work. Federal contract data comes directly from USASpending.gov; certification guides are written from primary sources at NMSDC, WBENC, NGLCC, Disability:IN, NaVOBA, and the SBA; and outcome data is contributed by real diverse business owners through our public survey.
Mario writes and edits much of the editorial content himself, working with subject-matter experts at certifying bodies and procurement offices to fact-check claims about eligibility, costs, and processing times. He personally reviews every certification guide before publication.
Mission
Make supplier diversity legible to every business owner who could benefit from it.
The federal government and Fortune 500 corporations spend hundreds of billions of dollars every year through supplier-diversity-aligned procurement: federal set-asides for 8(a), HUBZone, WOSB, SDVOSB; Tier 1 and Tier 2 spend commitments for MBE, WBE, LGBTBE, DOBE, VBE; and dozens of state-level programs. The dollars are real. But the on-ramps are scattered across a dozen certifying bodies, fifty state agencies, and an SBA portal that assumes you already know the acronyms.
SupplierDiversity.com is the single front door. We translate the rules, surface the data, and put the application steps in one place so a diverse business owner with no prior procurement background can move from "what is this?" to "I'm certified and bidding" without paying a consultant for the basics.
What we publish
Four bodies of work the platform exists to maintain.
Reference
Certification guides
End-to-end walkthroughs of every major certification: eligibility, documents, costs, processing times, renewal. Each guide is fact-checked against the certifying body's own published documentation at NMSDC, WBENC, NGLCC, Disability:IN, NaVOBA, and the SBA.
All certification guides →Data
Federal contract data
Every diverse-supplier set-aside contract awarded by every federal agency, sourced directly from USASpending.gov. Refreshed daily, queryable by agency, fiscal year, NAICS code, and certification type.
Federal contract database →Tools
Tools that do real work
Eligibility quiz, capability statement builder, NAICS lookup, government readiness score, revenue calculator, certification comparison. Built so readers can take action immediately, not just read about it.

Editorial principles you can verify.
Quality only matters if it's checkable. These are the standards we hold our editorial work to. Anywhere we fall short, point it out and we'll fix it and credit the catch.
Primary sources only
Certification facts are checked against the certifying body's own documentation, not third-party blog posts. Every program's website is linked. Federal data is pulled directly from USASpending.gov and the SBA's own datasets.
Named human authorship
Every article has a real, named author with a public profile, expertise areas, and contact methods. No AI ghost-writing without human review. No invented experts.
Disclosed conflicts
If we mention a paid product, including our own (CertifyAll, premium subscriptions), it's labeled. If a guide is sponsored, it's labeled. Affiliate relationships with lenders or financing products are disclosed at point of mention.
Datestamps and corrections
Every guide carries a "last updated" date. Corrections are tracked publicly with the original error and the change. We don't silently re-write history.
Independence
We don't sell certifications. We help you choose them.
SupplierDiversity.com is independent of NMSDC, WBENC, NGLCC, Disability:IN, NaVOBA, the SBA, and every other certifying body and program covered on this site. We don't accept payment to recommend one certification over another. Editorial coverage is editorially independent of advertising or paid placements where they exist.
Where we do earn revenue: premium subscriptions for buyers and suppliers, the CertifyAll unified certification submission service, and clearly-disclosed affiliate relationships with select financing partners. Read more in our editorial standards.
Editorial team
Co-founded and run by Will Moss and Mario Bailey.
Contributors at certifying bodies, procurement offices, and certified diverse businesses help us fact-check coverage and contribute case studies. Authors carry full bios, public expertise areas, and contact methods.
