Real SF Bay Area detectives.​

While others put liptstick on a pig and pretend to be local, we really are the "private investigator near me" you have searched for. Based out of Napa, we serve the entire Bay Area.

​

Pay for results, not billable hours.​

Our boutique private investigation agency is different. In most cases, we will bill for the project, not hours. With hours, you never know when your case will end. Perhaps, it ends when you're out of money. In contrast, we have clear up front all-inclusive pricing so you know what you're getting.

​

Boutique private investigator, not a big company.​​

We believe that small businesses make the world go round. The experience between private investigator and client should be closely guarded and kept safe, unlike dealing with admins, case managers, and hi-tech software.
