Ian Ho
Profile
I've been building things on the internet since before most people had it at home. Started as an engineer at eBay — their first Technical Architect — and spent the next twenty-five years crossing back and forth between technology and marketing until I stopped keeping track of which side I was on.
The pattern: build something, understand how growth works, build something else. eBay. Wynn Resorts. A decade running a performance marketing company. Years as a Fractional CMO. Now building AI security products and helping founders grow.
I work at the intersection of systems thinking and human psychology. The engineer in me builds things that scale. The marketer in me makes sure anyone cares. Bangkok-based. Occasional writer. See field notes below.
