I nearly partnered with a person who had such vile content online using an alternate identity, which would have hurt my business once our competitor put two and two together. I have no idea how you found what you found, but that’s why you are an expert in your field.
Thank you for helping resolve my cold case. Without you, there would have never been a conviction of my sister’s murderer. I don’t have words that really say how much this means to me. But thank you so much.

I should have just stopped trying to find the answers that I needed online using public resources that charged me for useless reports. You are a godsend, and I will be forever grateful that your report helped me make an informed decision that saved me thousands of dollars and years of grief! Thank you!
Without you, I wouldn’t have my granddaughter back! Having a missing child in my family is one of the worst things we have ever been through, and since her dad was hiding her, and the police wouldn’t help us, we are so grateful that you found her! Words are not enough. Thank you is not enough!
Just wanted to drop a line to let you know that you were the third investigator that we hired to locate these people, and you were the only one who got them to respond to our requests. Amazing job!
I wanted to let you know that because of your investigation, we did not put that influencer on contract with our brand, and thank God we didn’t! I mean, I don’t know how you do what you do, but you sure saved our bacon!
