Hojoon Lee

The house is called Hojoonbar. Friends come by for a drink and a chat — that's how it got its name. This site is that counter, moved to the internet.

By day, I run Korea Green Data, where we use energy data to cut power consumption in buildings and factories. Before that, I emptied two glasses of startup life in Silicon Valley.

What I write about

• Energy data & carbon — if you don't measure it, it won't shrink
• Changing how we work with AI (AX) — failure logs, not launch announcements
• Workplace safety — what data can actually do
• Founding & running companies — things I barely learned by the third one
