Built by investigators, for investigators
Founder Lee Lewis spent 15 years supporting UK agencies such as the NCA, national police forces, and HMRC. UserSearch was born from frontline needs and is still refined with real-world cases.
“I built UserSearch because I watched investigators burn precious hours on manual searches. Every minute saved is a minute that goes back into the case. That’s what keeps us moving.”
— Lee Lewis, Founder & Director
