Top Investigation Services Companies

A whistleblower alleges an executive is taking kickbacks, a lawyer needs to find a defendant's assets, an investor wants to know who really owns a target company. Investigation services handle these questions for businesses and their counsel: fraud and misconduct inquiries, background and due diligence checks, surveillance, asset searches, witness interviews and evidence collection that will hold up in court.

The investigation firms here include licensed private investigators, former law enforcement teams and global risk consultancies. Shortlist those that handle your type of case and jurisdiction, and check how they report findings for use in litigation or disciplinary action.

Buyer's guide

Hiring Investigation Services companies

What the work covers, how to judge a partner and what drives the price.

What corporate investigation firms do

Corporate cases begin with scoping: the allegation or question, the legal setting and who will rely on the findings. Investigators then gather public records, court filings, corporate registries and media; interview witnesses; run surveillance where lawful; and work with digital forensics specialists on email, devices and accounting records.

Common assignments include internal fraud and theft, harassment and misconduct inquiries, pre-deal due diligence on companies and executives, asset tracing for judgment recovery, intellectual property and counterfeit investigations, insurance claim checks and litigation support with witness location and evidence gathering.

Findings are delivered in a written report with sources and exhibits, and investigators may testify. Many firms are engaged through the client's outside counsel so the work can fall under legal privilege, and pricing is set per case or on a retainer for repeat work.

FAQ

Investigation Services FAQs

Short answers to what buyers ask before hiring a Investigation Services company.

Question not covered? Ask our team

Investigation services firms gather facts for companies and their lawyers. They look into fraud, theft and misconduct, run background and due diligence checks, trace assets, conduct surveillance and interviews, and deliver evidence in reports that can support litigation or disciplinary action.

Investigators bill hourly plus expenses, quote fixed fees for standard reports, or work on retainer. Many firms on Edverise start at $1,000 or have no minimum, while complex fraud and multi-country cases come from firms starting at $10,000 to $50,000.

A private investigator gathers facts from people, records and observation, while a digital forensics firm recovers and analyzes data from computers, phones and networks. Many corporate cases need both, and some investigation firms keep forensic examiners in-house or work alongside a specialist.

Choose a licensed firm with experience in your type of case and jurisdiction, and ask how it keeps evidence admissible. Check that it works lawfully, coordinates with your counsel on privilege, and has reach in every country your matter touches.

Business services, financial services and legal clients are the largest groups served by investigation firms in this listing, followed by medical, government and manufacturing organizations. Financial clients commission fraud and due diligence work, and law firms hire investigators for litigation support.

Investigation firms on this page are listed in Fort Lauderdale, London and New York, among many other cities. Licensing is local, so the investigator, or a licensed partner, should be authorized in the place where the inquiry is carried out.
