Private Investigation for Attorneys and Clients in Criminal, Civil, Business, and Personal Matters.

Sebastien Wiggs is a licensed private investigator based in San Francisco handling sensitive, high-stakes matters for attorneys, businesses, and private clients. With nearly twenty years of experience, his practice spans criminal, civil, and family matters, plus workplace reviews and background checks.

Clients retain Sebastien to examine opposing parties and key witnesses. He distills investigative findings—gathered through field interviews, public records, open sources, and proprietary databases—into clear reports lawyers use in court, negotiations, or strategy sessions. He delivers testimony as needed and conducts post-trial juror interviews.

Companies rely on him to vet key hires, map business relationships, and quietly probe concerns around confidential information or unfair competition.

Sebastien remains closely involved across all assignments, tailoring his approach to each case and helping clients make informed decisions grounded in thorough investigative work.
