What Diligentia Group does
Diligentia Group is a boutique private investigation firm operating as Diligentia Group Inc. from Katonah, New York. Founded and led by Brian Willingham, a Certified Fraud Examiner (CFE), the firm provides professional investigative services to four primary client segments: law firms, businesses, investors (including private equity and financial institutions), and private individuals. Core offerings include Background Investigations, Due Diligence Investigations, Legal Investigation (witness location and interviewing, intelligence gathering against legal adversaries), Asset Investigation (real property, UCC filings, hidden assets), People Location Services, Executive Background Checks, Pre-Litigation Asset Searches, and Business Partner Vetting.
The firm's underlying methodology is open-source intelligence (OSINT) gathering supplemented by licensed access to professional-grade investigative databases — IRB, TLO, Merlin, Courtlink, Factiva, Lexis Nexis — alongside public records, civil and criminal court filings, and a developed network of specialized contacts in physical surveillance, cybersecurity, forensic accounting, and fraud examination. The firm does not operate a software platform or API; deliverables are produced as professional service work product.
Diligentia Group operates on a project-based, consultation-driven professional services billing model with no publicly disclosed pricing. Go-to-market is sales-led, anchored on a content marketing engine of 700+ blog pages, an email newsletter with 2,000+ subscribers, podcast appearances across PI Magazine, PI Perspectives, ACFE Stories, and others, and earned media coverage in Wall Street Journal, Washington Post, MarketWatch, ABA Journal, and Fraud Magazine. A free educational guide on hiring a private investigator functions as mid-funnel lead capture. The firm is privately held with no institutional funding, acquisitions, or partnerships disclosed.
