Private Investigation Agencies
A private investigation agency is a licensed firm of professional investigators that handles cases for attorneys, insurance carriers, businesses, and private clients across the United States. Agencies typically offer broader service coverage, multiple investigators per case, and the operational infrastructure that complex investigations require.
Investigator Jobs Portal connects both sides of the private investigation agency ecosystem:
- If you’re looking to hire a private investigator: Whether you need a single investigator or a multi-specialist agency, start by posting your case through our job portal.
- If you’re a private investigation agency:Use the platform to post subcontract jobs, hire full-time PIs, or extend your case capacity nationwide without expanding overhead.

What Is a Private Investigation Agency?
A private investigation agency (also called a PI agency or private detective agency) is a licensed firm that conducts investigations on behalf of clients. Unlike independent solo investigators, agencies typically employ multiple licensed PIs, handle higher case volume, offer multi-disciplinary specialties under one roof, and maintain the operational infrastructure (case management, reporting, billing, compliance) that complex investigations require.
Most US states regulate private investigation agencies through licensing boards that oversee both individual investigators and agency operations. State requirements vary; see official PI licensing websites for all 50 US states for jurisdiction-specific information.
Private investigation agencies range from:
- Solo-led agencies; a licensed lead investigator with a small team or subcontractor network
- Regional firms; multi-investigator agencies serving a specific metro or state
- Multi-state agencies; larger firms with licensed coverage across many jurisdictions
- Specialty agencies; firms focused on a particular type of work (insurance fraud, corporate investigation, surveillance, background screening)
Why Work with a Private Investigation Agency
Clients hire private investigation agencies, rather than solo PIs for several reasons:
- Capacity: Agencies can dedicate multiple investigators to time-sensitive cases (surveillance teams, multi-state coordination, parallel work streams)
- Specialty coverage: Larger agencies often have specialists in forensic accounting, computer forensics, surveillance, and background work all under one engagement
- Geographic reach: Multi-state agencies handle interstate matters with licensed investigators in each jurisdiction
- Operational reliability: Established agencies maintain insurance, bonding, case management systems, and reporting standards expected by law firms, insurance carriers, and corporations
- Continuity: If one investigator is unavailable, agencies have backups; solo PIs don’t
- Vendor compliance: many corporate and insurance carriers require licensed agency engagement rather than 1099 solo investigators for vendor-risk reasons
When you hire a private investigator through the Investigator Jobs Portal, you can engage either a solo investigator or an established private investigation agency, whichever better fits your case.

Frequently Asked Questions About Private Investigation Agencies
What’s the difference between a private investigation agency and a solo private investigator?
A licensed PI works independently; a private investigation agency is a licensed firm with multiple investigators, typically offering broader service coverage and operational capacity. Both must be properly licensed. Larger cases often benefit from agency engagement; smaller, single-investigator work may be efficiently handled by a solo PI.
How do I find a private investigation agency near me?
Post your case on the Investigator Jobs Portal and receive proposals from agencies and investigators in your area. You can filter by location, specialty, licensing, and ratings to find the right fit. Our licensing websites by state directory also provides official PI regulatory boards in every US state.
Are private investigation agencies licensed?
Yes! In most US states, both individual private investigators and the agencies they operate under must be separately licensed. Requirements vary by state. Every agency on Investigator Jobs Portal is licensed-verified before they can engage clients or post jobs.
How do agencies use Investigator Jobs Portal?
Agencies use the platform to (1) hire full-time investigator employees through the job board, (2) subcontract case overflow to qualified independent PIs, and (3) extend geographic coverage by engaging licensed PIs in states where the agency doesn’t have in-house staff.
Can my agency post jobs in multiple states?
Yes. Agencies can post subcontract jobs and full-time openings in any US state. For cases requiring multi-state coordination, the platform supports coordinated engagement across multiple licensed investigators.
What’s a subcontract PI job?
A subcontract PI job is a case engagement where one agency hires an independent licensed investigator on a 1099/contract basis to handle specific case work. Agencies use subcontracting to extend capacity, cover unfamiliar geography, or access specialty experience. See private investigator subcontractor jobs for more.
Does the platform replace recruiters and staffing agencies?
