Most investigators follow people. We interview them. Most investigators photograph situations. We analyze, document, and deliver findings that hold up - in a courtroom, a boardroom, or a conversation that matters.

KB Tenacious is a licensed private investigation and behavioral intelligence firm based in Washington State. We work primarily with civil litigation attorneys, businesses conducting due diligence, and individuals who need the truth found the right way.

Our principal investigator holds Paul Ekman Group micro-expression certifications and is trained in behavioral analysis - the same foundations used in structured truth assessment. We apply those tools to real cases, with documented methodology and legal defensibility.

We don't do domestic surveillance. That's a choice, not a limitation.
