ABOUT WILLIAM KO
I help enterprises turn messy data into commercial value through end-to-end data and systems transformation.With 16 years of experience spanning Amazon and high-growth startups, I\'ve built and led data organisations, architected cloud platforms, and delivered transformation programmes that drive commercial outcomes.At Amazon, I was a Head of Data Analytics and Science and led a multinational team of 15+ engineers and analysts delivering customer insights, commercial analytics, and growth strategies. Since then, I\'ve worked as a Principal Technical Architect and interim data leader for FTSE100 and F500 enterprise clients and venture-backed startups - from large-scale data platform transformations at major UK telecoms to greenfield builds for social commerce scale-ups.I work with executives and founders who need to accelerate their data maturity, establish governance frameworks, and turn data into a commercial asset rather than a cost centre.My work spans: • E2E data and technology platform architecture and technical implementation (AWS, GCP, dbt, modern data stack) • Building data and tech capabilities that unlock 8-figure commercial value • Accelerating data maturity and evolving data functions into strategic growth assets • Building and scaling high-performing data and technology teams• Advising SLT on data and technology investment and commercial prioritisationI operate through Towards Insights Ltd, typically on retained or project engagements.
