I am an entrepreneur and investor.

I was born in China. (Chinese translation of this page) And I grew up in the San Francisco Bay Area as a first generation immigrant.

Given my middle-class upbringing, I chose a very safe, very traditional way to start my career – at Goldman Sachs. (More context in: The privilege to take a risk)

Afterwards, I worked for 3 years at a fundamental-value hedge fund. After 20 years in the Bay Area, I moved to Boston in 2016 to pursue an MBA at MIT Sloan.

While at MIT, I co-founded DeepBench. We connect customers with experts on any topic in any industry.

I now operate a start-up studio called Optionality Partners. I use my own capital and that of a few close friends to build businesses and invest in companies.

My hobbies include reading, writing, and playing poker.

Currently, I live in Los Angeles.

My why

The reason for this site is three-fold:

  1. I am on a lifelong journey to better understand how our world works.
  2. In order to generate capital and perpetuate this quest, I plan to use what I learn by investing in existing businesses and starting new businesses.
  3. It’s no fun, and not to mention impossible to do this alone, and so I hope to find collaborators with intelligence, energy, and integrity to join me on this adventure.

I hope to find others who share my curiosity and excitement about business topics. I wish to create a network of peers interested in learning and working together.
