Stefanie Nastou

I've spent over 20 years transforming marketing into a strategic growth engine, aligning brand, demand, and revenue to drive real commercial impact. From scaling global marketing teams to repositioning brands in complex markets, I've led go-to-market transformations across B2B and B2C SaaS, private equity-backed companies, and Fortune 500 organizations. I'm passionate about building marketing functions that do more than support the business, they power it. That means creating operational clarity, leading with purpose, and bringing together the right mix of data, storytelling and innovation to deliver outcomes that matter to the boardroom and the customer. Along the way, I've developed a leadership philosophy grounded in resilience and reinvention. As the author of RuleBreaker Mindset, I help others lead with authenticity, challenge the status quo, and build cultures where bold ideas thrive. I actively mentor women in tech and advocate for inclusive leadership. Recognized among the Top 50 Women in Tech and Most Influential Women in Marketing 2023 by CIO Look magazine, for me, great marketing is the result of bold leadership, clear vision, and the courage to reimagine what's possible.
