Background

About Gemma Platt

Strategic and results-driven marketing leader with over 15 years' experience delivering impactful B2B marketing programmes across the technology landscape—from hardware and software to cybersecurity and developer ecosystems. I’m passionate about building initiatives that scale, teams that thrive, and campaigns that make a genuine difference. Currently leading Developer Marketing at Arm, where I built and scaled a global developer programme in just eight weeks—aligning outreach across the business and unlocking new opportunities through strategic event presence (GDC, Microsoft Build, KubeCon) and community engagement. I’ve also driven go-to-market success for developer tools and platforms including Success Kits and Arm IP Explorer. With a background in product marketing, sales alignment, and executive leadership, I bring a balance of creativity, commercial acumen, and operational discipline. I’m especially proud of my work embedding DEI into our approach, championing representation and inclusive practices that support women in tech. I thrive in fast-paced environments, enjoy tackling complex challenges, and believe that great marketing is all about connection—whether with developers, partners, or peers.
