About
I’m Marcio Gessoni, a Growth Engineer and full-stack builder who bridges the gap between growth strategy and production engineering. I’ve spent the last decade designing acquisition, attribution, and outbound systems—then shipping the code that makes them measurable—working with B2B tech, e-commerce, and industrial teams across the US, Canada, Europe, and LATAM.
My background includes 10 years at Mercado Libre, where I owned product and marketing for an online-store platform across multiple countries, and earlier I helped launch Yahoo! Brazil’s search advertising products. Today I work end to end on outbound infrastructure (Clay + Apollo, enrichment, verification, deliverability), AI-agent automation with MCP-accessible APIs, analytics/BI pipelines (GA4/Looker Studio), and paid growth measurement so teams can improve CAC and LTV with confidence.
