Why most ad budgets underperform
Paid visitors decide in seconds. A long form, a busy header, a slow first paint — any of them turns the click into a loss. The market already measured the damage.

Verifiable standards
Marketing claims can be written. Technical specs either hold up under inspection or they don't. Here are the three pieces of infrastructure you can verify independently.
Events sent directly from our server to Meta's endpoints. SHA-256 hashing of email, phone, fbp, fbc. eventId deduplication between the browser pixel and CAPI: no event counted twice, none lost when iOS or Safari block the script.
Read from the query string at the page's first render and saved on the lead before the user touches the first field. Works even when Safari ITP blocks 3rd-party cookies. No GTM scripts to write, zero latency.
EU data residency by default. DPA available at signup, cookie banner and consent versioning built in, subject rights handled in the dashboard. Audit log is immutable and exportable.
FAQ
Most form builders either price per response (so cost scales with success) or treat performance-marketing features like CAPI and attribution capture as DIY add-ons. Fluenx is purpose-built for paid traffic: flat monthly pricing per lead volume, native server-side CAPI, UTM and click-ids captured without scripts, conditional endings baked in. On paid-traffic funnels, that combination is what moves CPL.
