Zachary Leifer
Fortune 500 CMO | Executive Technology & AI Experience | Conversion Mercenary
About
Fractional CMO with 20+ years leading marketing for Fortune 500s and startups — gaming, hospitality, sports media, SaaS, eCommerce, luxury retail. Results: $36M in new channel revenue, 67% growth over 4 years, 56% CAC cut, 73% LTV/CAC gain. Deep in martech, customer data platforms, and AI. I diagnose what's blocking growth, then run marketing like an operator. Cornell + Harvard AMP.
I drive revenue growth, improve EBITDA, and help organizations turn customer insight, data, technology, and AI into measurable business results.
My career has increasingly operated at the intersection of commercial growth, marketing, technology, and enterprise transformation. I’ve served as a CMO and CCO, led digital and eCommerce businesses, and was recruited from marketing leadership into Corporate IT at a Fortune 500 company. That combination has shaped how I approach growth: not as a marketing problem, but as an enterprise problem requiring alignment across customer strategy, product, pricing, technology, data, operations, and execution.
At 1/ST, I led marketing across a $1.5B organization spanning B2B and B2C businesses. During my tenure, the business delivered 67% revenue growth and 22% EBITDA CAGR while we reduced customer acquisition costs by 56% and improved LTV/CAC by 73%. At The Venetian Las Vegas, I secured $13M in capital investment and helped generate $36M in incremental direct-channel revenue through digital transformation, eCommerce, pricing, personalization, and customer experience initiatives.
I have led organizations and initiatives across gaming, hospitality, entertainment, SaaS, wagering, and eCommerce, with responsibility spanning go-to-market strategy, customer acquisition and retention, CRM, product, pricing and yield management, digital transformation, enterprise technology, sales, customer success, and organizational change.
What connects those experiences is a consistent operating philosophy: find where growth is being constrained, establish clear priorities and accountability, align the organization around the highest-value opportunities, and use data, technology, customer insight, and disciplined execution to unlock measurable value.
I recently completed Harvard Business School’s Advanced Management Program, where my work focused on strategic leadership, organizational alignment, digital transformation, artificial intelligence, and enterprise value creation.
I’m most interested in CMO, CCO, GM, and broader commercial leadership opportunities where the mandate extends beyond managing a function to building the systems, capabilities, and organization required for sustainable growth.
