Marshall Clark
I help growth-stage companies build the marketing and sales engines that turn early traction into scalable, predictable revenue.
My career spans the full arc of modern growth marketing — from founding one of the first search marketing agencies in the late '90s, to product innovation leadership at Nielsen and IPG, to managing enterprise-scale media programs for Microsoft and Chrysler, to building B2C growth engines at venture-backed fintech companies.
For the last 11+ years I've focused on what I do best: designing and building the data, software, marketing, and sales systems that efficiently acquire high-value customers at scale. I've done this as a founding marketing leader, as an interim CMO, and as an advisor — always with a bias toward hands-on execution over strategy decks.
I bring a founder's mindset to every engagement: customer-focused go-to-market strategy, efficient pipelines, high-performance sales processes, and cost-effective revenue generation.
