How we help
Every situation is different, and every investigation starts with a conversation. We listen, answer your questions, and recommend the best approach based on your goals. Whether you need proof, peace of mind, or evidence for court, we’re here to help.
-
Infidelity
Discreet infidelity investigations that give you clarity instead of endless second-guessing. The most common call our Austin team gets starts with “I feel crazy, but…” — and you’re almost never crazy. -
Child Custody
We document what’s really happening during the other parent’s time, so your attorney has facts instead of he-said-she-said when it matters most.
-
Background Checks
Know who you’re really dealing with — a new hire, a business partner, or someone your family just got serious with. We find what surface searches miss. -
Surveillance
Professional surveillance across Austin for personal, legal, and corporate matters — documented with clean timestamps and chain of custody.
Investigations
Who we serve
Northwest Austin has its own rhythm, and working it well takes investigators who understand master-planned communities — limited entry points, HOA patrols, and heavy commuter flows along Brushy Creek Road and Parmer Lane. We know those daily patterns, not just the map, so we can set up without standing out and deliver accurate results.
