Diogenes LLC

What Diogenes LLC does

Diogenes LLC is a full-service private investigative agency founded in 2000 and headquartered in Milford, Connecticut, operating under Connecticut Private Detective License #A-2042. The firm is led by Managing Member Bradford Cole, a Certified Fraud Examiner with 34 years of investigative experience, supported by personnel averaging more than 20 years of experience. It serves the legal and corporate communities across Connecticut, New York City, Massachusetts, Rhode Island, and through national associates and international affiliates for broader U.S. and global engagements.

The agency's core offerings span theft and fraud investigations, intellectual property and economic espionage investigations, surveillance (land, sea, and air), undercover operations, litigation support (witness locates, juror dossiers, asset discovery), background investigations and due diligence, and a Technical Services suite that includes polygraph examinations, computer and digital forensics using EnCase and FastBloc, TSCM electronic surveillance detection, covert CCTV/video, and email tracking. Its technology stack is anchored by specialized investigative software drawing from databases of over 30 billion records across public records, court databases, police databases, and proprietary non-public information sources, with IRS record access for income verification.

Diogenes operates on a sales-led, direct-engagement go-to-market: clients reach Managing Investigator Brad Cole directly by phone or email for a free consultation, receive customized written proposals and cost estimates per case, and benefit from individual case supervision. Pricing is bespoke with no public rate card, and payment is accepted via major credit cards and PayPal (subject to a 4% convenience fee). Revenue is not publicly disclosed, the firm is privately held with no institutional investors, and no funding rounds or M&A activity are on record. The website copyright spans 2000-2018, indicating a low digital refresh cadence typical of a relationship-driven boutique rather than a scaling agency.
