LookupSwiss is a Swiss-grade phone and email validation API built for developers and SMBs. We founded the company in 2025 in Zürich with a clear mission: clean data, less fraud.
Every signup form, every checkout, every cold-outreach list is leaking money to typos, disposables, and outright fraud. We exist to plug that leak with one tiny REST call.
Every endpoint engineered to the millisecond. No flakiness, no half-built features.
We do data validation. That’s it. No bloated product portfolio dragging us off mission.
GDPR-grade. Swiss FADP-grade. We never sell logs. Your customers stay your customers.
A REST API you can integrate in 60 seconds. No SDK lock-in. Honest pricing in CHF.
