HtPi is a personal lab where I use ideas from finance, data and design to make sense of everything else.
HtPi reads as the Pi of Hₜ. ∏ is the product operator — the twin of the summation sign Σ. Where Σ adds, ∏ multiplies; where addition accumulates, multiplication compounds.
The subscript t marks time — H, for Horris, changing across a series. Taken together, ∏Hₜ represents one person's knowledge compounding over time, perhaps gradually becoming a way of thinking in its own right.
In Chinese, it can also be read as "HT派" — the HT school, or school of thought, if you'll forgive the pun. It sounds rather systematic. In practice, it often just means putting a few apparently unrelated things together and seeing what happens.
∏ Hₜ = H₁ · H₂ · H₃ ⋯ Hₜ
FinanceDataDesign
Add knowledge together and it grows — but linearly. Each field stays in its own column, useful and separate.
Multiply it and it compounds — fields fold into one another and take on a form none could reach alone.
Data Science & Technology Consultant · Hong Kong
I work where finance, data and design meet — and twenty years in, I'm more certain than ever that the interesting things live at the confluence, not in any single channel.
H₁Code
I started programming at six, although my career did not remain entirely in technology.
H₂Finance
Earlier on, I worked across financial analysis, investment evaluation and regional strategy at AXA and Telstra International.
H₃Data & AI
Later, I moved further into data science, AI and technology consulting.
H₄Ventures
Along the way, I was also involved in the Thomson Reuters–Systex venture and founded WeMine Labs, helping organisations work through questions involving AI, data and digital transformation.
H₅Study · AISU
I hold a Master of Applied Data Science from the University of Michigan and the GARP Certificate in AI and Risk. I also founded AISU in 2002, one of Hong Kong's early AI organisations.
H₆Teaching
These days, alongside consulting, I occasionally teach at universities and professional institutions.
HₜHtPi
HtPi is the workbench beside my day job: a place to write about questions without standard answers, and to take ideas from different fields apart, recombine them, and see whether anything useful emerges.

Beyond the writing here, I've also shared what I see in data, technology, AI and digital markets — in interviews, classrooms and public discussions. A few of those records follow.
Here, I put questions from different fields on the same table and see whether they can help answer one another.
