About Lin

Who am I

I'm Lin Cheng, the Founder of Great Idea Technology, a venture studio company. I describe myself as someone who is learning TAO/道 — a part-time investor, researcher, food inventor, poet, writer, YouTuber, and personal trainer.

What I do

I wear many hats and enjoy exploring the intersection of technology, business, health, and creativity:

• Technology & Entrepreneurship — As the founder of Great Idea Technology, I build and incubate technology projects that solve real-world problems.
• Investing & Research — I research and invest in opportunities across technology, business, and emerging markets.
• Writing & Content Creation — I share insights through this blog, covering topics from business strategy and technology to health and creative fiction.
• Health & Wellness — As a personal trainer and health enthusiast, I'm passionate about helping every individual live a healthier life.

My mission

Make every individual healthier. I use “health” broadly: physical and mental well-being, but also people's ability to think clearly, make good decisions, use better tools, and act effectively. This belief drives everything I do — from the technology I build to the content I write and the people I work with.

About this site

This site is a persistent, first-hand record of things I build, test, and examine — software I've built, products I've tried, details I've noticed, and conclusions I've changed my mind about. The topics are broad; what stays constant is the pattern: build, test, observe, judge, update, share. You could think of it as an opinionated sensor for the web. It is operated by Great Idea Technology Limited, a company registered in the United Kingdom.
