Marketing & Revenue Operations Leader
4+ years building growth systems, scaling operations, and driving revenue for B2B companies through demand generation, marketing automation, and AI-powered workflows.
About
I've spent 4+ years helping B2B companies turn operational complexity into repeatable revenue. At Sellerant, I lead operations across demand generation, content strategy, competitive intelligence, and marketing automation, building the systems that power a revenue growth services firm. Before that, I co-owned and operated Proclaim, a B2B podcast production agency where I managed a team of 15 and built the infrastructure that led to its acquisition. I think in workflows, build with AI, and care about doing the work that makes growth sustainable.
