About Mario ….
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.
