Private Investigator Business
Offer lawful investigations to attorneys, insurers and individuals.
TL;DR
A private investigator business performs lawful investigative work such as background checks, surveillance, locating witnesses and gathering evidence, usually for attorneys, insurance companies and businesses. Most states require a PI license with experience or training requirements, and the work must follow privacy and evidence laws. Repeat clients like law firms are the foundation of a steady practice. Expect to spend about $2k–$15k to start, earn your first dollar in 1–4 months, and reach roughly $2k–$12k/mo after a year of steady work.
§ 01
Why a Private Investigator Business works now
Law firms and insurers regularly outsource fact-finding, and digital evidence adds work around social media, public records and video. Clients value discreet, well-documented investigators who understand what evidence will stand up. Online databases give solo investigators powerful research tools, subject to strict legal limits.
