    This International Women’s Day 2025, we embrace the theme of "Accelerate Action"—taking steps to positively impact women's advancement. At DayOne, we put this into practice by launching our first Women in Data Centers Committee, dedicated to fostering mentorship, championing women’s career growth, and ensuring greater representation in digital infrastructure. To mark this occasion, Jamie Khoo, CEO of DayOne, shared her journey in a fireside chat on March 7 with our team in Singapore and online, connecting with colleagues across Malaysia, Indonesia, Thailand, Japan, Hong Kong SAR, and beyond. As a woman leading a high-growth digital infrastructure company, she reflected on the challenges and triumphs of building DayOne from the ground up over the past three years. Her message was clear: action drives change. Women in leadership bring resilience, compassion, fearlessness, and the ability to stand by their principles—qualities that not only fuel individual success but also drive industry-wide transformation. Her advice to women striving for leadership: 🚀 Be fearless and assertive—stand by your principles 🚀 Earn respect and success through capability and continuous learning 🚀 Every little success is a success—push through challenges and deliver results 🚀 Find mentors who challenge and support you At DayOne, we believe in taking action today to shape a more inclusive tomorrow. As we celebrate the achievements of women across DayOne, our industry, and society, let’s keep accelerating the momentum for real, lasting change. #IWD2025 #AccelerateAction #WomenInTech #WomenInLeadership #DigitalInfrastructure #DayOne
