About
Growth marketer building 0→1 GTM engines across SaaS, deep tech, hardware, and robotics. I turn marketing activity into measurable pipeline and revenue through global, cross-functional programs. I'm currently leading marketing as an operator, while building the infrastructure that makes agentic commerce work as a co-founder.At Sartorial, I'm building the layer that lets AI agents reliably navigate and transact on e-commerce catalogs. I came to it from the merchant side, having run Shopify storefronts end-to-end and watched firsthand where today's agents break down in real commerce environments.Before founding, I was the first U.S. marketing hire at Orbbec (a $2B company focused on robotics, AI, and 3D machine vision), where I built the entire demand-generation function from scratch while managing their Shopify storefront end-to-end: storefront build, frontend optimization, supply-chain coordination, conversion funnel, and data tracking. +32% QoQ marketing-sourced pipeline; -73.7% CPL YoY2.4x ROAS improvement through paid channel segmentation and testingDeep Tech Storytelling: BBC StoryWorks co-production, 2.7M impressions, 709K views, 280 MQLs from target accounts20+ product launches across U.S. and EU marketsEnd-to-end attribution: UTM → GA4 → HubSpot → CRMCross-industry track record: +40% qualified leads / 4.6x ROI (Siasun - Robotics), +30% SQLs / +20% ARR (Helios - B2B SaaS), +25% leads / -10% CAC (EAC - Education).
