About Me



I'm a Platform Product Marketing Manager with over a decade of experience embedding myself in product and engineering teams. I learn how complex systems actually work, then translate that depth into narratives that drive pipeline, adoption, and expansion.

My career spans AI-driven SaaS, digital watermarking, mobile commerce, and automotive B2B, but the throughline is consistent: I build the positioning, content, and enablement infrastructure that gives revenue teams the clarity and confidence to win.

I'm completing my MBA at SMU Cox School of Business with a focus on strategic leadership.

I don't just write about AI. I build with it. I develop custom Claude AI skills for GTM workflows and hold certifications from both Harvard Business School Online and the Product Marketing Alliance.

Why Alexia

Not all PMMs are
built the same.
