Kaye Sumanga
Head of Procurement @ Grab
About
I drive transformation with a bold mix of commercial acumen, systems thinking, and a deep understanding of human dynamics. As Head of Procurement, I’ve led high-stakes transformations across Southeast Asia, delivering 200%+ of targets while building resilient, future-fit teams and restoring trust in Procurement as a strategic partner. What sets me apart? I’ve sat on all sides of the table: Business (I am an ex Marketer), Supplier (I grew from the ranks of cross discipline Agency world), and Procurement (I earned my stripes not from theories, but real practice end to end) - which gives me a rare, 360° lens on commercial negotiations, risk management, stakeholder dynamics, and business intent. This triple vision has been my superpower in cutting through noise and enabling Procurement to lead with influence, not just process. Highlights: • Procurement Transformation Architect – Twice over. From rebuilding foundations (policy, governance, operating model) to leading a region-wide transformation with double the commercial impact and stronger alignment to business growth. • Digital Systems & P2P Reimagination – Led the Procure-to-Pay workstream of a broader Digital Finance & Systems Transformation, reengineering workflows, modernizing systems, and navigating change adoption with clarity and grit. • Trusted Bridge-Builder – Closed the gap between strategy and execution, regional and local. Placed premium in people capital and the power of breaking silos towards unified passion to a shared vision. Repositioned Procurement from tactical executor to strategic enabler. • Change Catalyst Beyond Procurement – Steered Change & Communication strategy for Finance Transformation—ensuring leadership sponsorship, operational readiness, and business adoption in the face of resistance and fatigue. Multiple times described as a “unicorn leader,” I combine intellect with empathy, urgency with clarity, and structure with imagination. I build high-trust, mission-led teams that don’t just deliver, but elevate the standard. I believe transformation doesn’t happen by process or systems alone. It requires purpose, storytelling, and the courage to ask “what if?”, then the unshakeable resolve to make it real.
