About
I’m Jimmy Chang, a growth marketer with 6+ years of experience across user acquisition, paid media, and SEO. I’ve managed USD 4.5M+ in ad spend for brands including LEGO, Dyson, Sony Pictures, and Bloomberg, running campaigns across APAC and the US with a strong focus on measurable performance and fast iteration.
I enjoy building systems that improve acquisition efficiency—using conversion tracking, funnel optimization, and A/B testing to reduce CPA and accelerate ROAS decisions. Most recently, as a founder and growth marketing consultant, I’ve delivered major improvements in cost efficiency and booking growth for hotel and B2B clients, and I’m also developing AI-driven agent and chatbot experiences to scale experimentation.
