What customers say on Trustpilot
See how businesses like yours are preventing fraud, improving data quality, and increasing revenue with 1Lookup
"Been using 1Lookup for a couple months now. We verify leads before pushing them into Pipedrive. Honestly it just works. Not fancy, not buggy, and the support actually answers when you write them. Can't really ask for more."
Brian Letzter
Verified review via Trustpilot, October 2025
"We use 1Lookup inside our telemarketing app to verify numbers before they go to the dialer. Setup was simple and the results have been consistent. It's not overloaded with features, just fast, accurate, and reliable. Docs could be a bit deeper, but honestly, it works out of the box."
Dirk van Meer
Verified review via Trustpilot, December 2025
"We run a SaaS product with free trials and were getting flooded with bots and fake users. After integrating 1Lookup, the difference was night and day. It quietly filters out junk signups without blocking legitimate customers. The support team even helped us fine-tune our risk thresholds on a quick Zoom call. Being honest, we couldn't ask for more."
