About
Hey, I'm Marielle — a GTM Engineer specializing in Clay automation and data-driven outbound systems. I help B2B teams transform scattered data into scalable, revenue-generating campaigns. By combining advanced Clay workflows, AI-powered personalization, and multi-source enrichment, I design outbound engines that deliver qualified opportunities at scale. I've spent my career building complex automation systems at top Clay agencies including Growth Engine X (elite Clay partner) and OneAway — now I help others turn data signals into pipeline that actually converts.
