Breanne ByrneFounder, The Modernist Advisory
Fractional CMO & Strategic Advisor
I help CEOs bring clarity to their next stage of growth, connecting marketing, customer experience, and the people who make progress possible.
My career spans enterprise leadership, entrepreneurship, and business transformation. I’ve led marketing and customer experience for a national healthcare organization, co-founded and grown a consumer brand, and shaped brand and go-to-market strategy for an AI-native business. That range gives me a practical understanding of both the ambition behind a business and the decisions required to move it forward.
At Octapharma Plasma, I led work across brand, digital strategy, customer experience, and organizational change. Building Bump & Run Apparel brought the founder’s perspective: taking an idea to market, developing customer relationships, and making thoughtful choices about where to invest. My work with Syntari brings that experience into the evolving relationship between human expertise and AI.
Through The Modernist Advisory, I bring that perspective to CEOs of small and midsized businesses across industries. We clarify what your business needs from marketing, align the team around a shared direction, and create a practical path from strategy to execution.
My approach combines clear expectations with a deep respect for people. I work closely with leadership and the team doing the work, building the trust, ownership, and confidence that help change take hold. The goal is a marketing function that strengthens your business and a team equipped to carry it forward.
