Katherine Macri is the CEO of Group Forty Three, providing strategic intervention and executive direction for businesses navigating complexity and growth.
Katherine serves as a Fractional COO for founders
who need clarity, direction, and decisive leadership.
She is known for seeing what’s actually happening inside a business —
quickly — and cutting through noise, misalignment, and confusion.
Group Forty Three operates as an agency, with Katherine leading strategy and problem identification and activating execution support when needed.
Alongside selective human engagements, Katherine created HER-OS™ — a private clarity operating system built from her decision logic and pattern recognition. HER-OS is designed for founders who need support in the moment, without requiring access, and operates independently from Group Forty Three’s human services.
“I am increasingly engaged to translate operational intelligence into private AI systems that support decision-making, reduce leadership load, and stabilize execution as businesses scale. Rather than building technology for its own sake, I design AI as decision infrastructure — systems that encode how a business actually thinks so clarity, logic, and direction hold without constant human intervention. This work is becoming a core extension of my strategic practice and a defining element of how I support modern leadership.”
