The GTM problems Marshall solves
Marshall solves growth stalls caused by leadership friction, unclear ICPs, fragmented focus, and strategy that stops running after offsites. When leaders agree in meetings but pull apart after, or when founder-dependent decision-making bottlenecks execution, Marshall aligns leadership around focused priorities and operating rhythms. He works across marketing, sales, product, customer success, and operations rather than in a silo, using the GTM Operating System (GTM OS) to connect strategy to cross-functional execution. Marshall identifies where friction is holding the business back, helps reset roles, and implements structured operating rhythms to keep plans moving forward.
Track record
Marshall brings over 20 years of commercial leadership experience spanning $1B+ industrial technology companies to founder-led operators. He is a Gold status GTM OS Certified Partner and a Certified Working Genius Facilitator. His past engagements include generating 71% more sales in eight months for a $10M consumer goods manufacturer by establishing clear ownership and lanes among co-owners. He helped a newly acquired agency achieve 57% more revenue the following year by identifying, repricing, and focusing on profitable services. Additionally, Marshall helped a SaaS company increase profit by 41% the following year by defining its ideal customer profile and adjusting sales compensation.
In Marshall's words
Growth is a clarity problem, and Friction is the enemy slowing down your business. I help founders and leadership teams find the friction holding growth back, in how they work together, where they're headed and how they'll get there, then guide the work to clear it.
