Founder, LeadSignal
Daniel Kalcher founded LeadSignal because conversion tracking has become far too complicated for most advertisers: pixels, Google Tag Manager, server containers, consent banners and privacy rules rarely fit together cleanly. As CTO of LeadMetrics he leads the technology behind tracking, attribution and the Conversions API. On this blog he writes about how to get accurate conversion data into Meta, Google, LinkedIn and TikTok with simple means - GDPR-compliant and without a developer.
