“No referral/share mechanics. Free public lookup tools (e.g. 'Who Called Me?') and 'Invite teammates and share one credit balance' (team seats). Grey note: skip trace / reverse phone lookup / ringless voicemail products.”Quote from the site
New-user source: Other (Direct / referral / email / paid). Similarweb 2026-09: the top channel is referrals at 38.36%, followed by organic search and direct, but 73% of referral sources fall into a hidden category, so the specific sites can't be seen. Besides the brand keyword 1lookup, search terms include lookups.io, 'see instagram profile free', and the Russian query '1lookup по каким странам работает'. The country mix is spread out (United States, India, Turkey, Brazil, Russia), which suggests part of the traffic comes from free reverse-lookup tools. The website has a referral program with a 20% recurring commission (90-day attribution, paid monthly via Wise) and 'vs Twilio Lookup / vs ZeroBounce' comparison pages. Social is X only. TrustMRR has no founder-reported channels. Similarweb rank is around 750K; site traffic is tiny while monthly revenue is about $400-500K, which suggests revenue comes mainly from direct API calls and in-account top-ups.
