About
Taiwan. Naperville. MIT. A life I love building.
I was born in Tainan, Taiwan. The early years were across Taiwan — dirt lots, marbles, pickup baseball, and school rankings in first grade. I love to compete, and I still bring that energy to everything I build.

Who is James Chen?
I am James Chen — people still call me mitnerd. I am Chief Technology Officer at Immortals, an MIT Course 6 graduate (B.S. Electrical Engineering and Computer Science, 1996–2000), and a happy builder. I love shipping technology that helps people live longer and healthier, and I am a supporter of Bryan Johnson, Blueprint, and science-backed longevity.
The family moved to the United States when I was eight. Dad took the chance in a week. He was the only one who spoke English. We bounced through Lodi, California and South Bend, Indiana, then four more times between fifth and sixth grade, and landed in Naperville — the Chicago suburb he chose as the right place to raise us. He made that future happen.
Naperville North is where I found my people: computer club, chess, math team. The math team threepeated as Illinois ICTM AA state champion from 1994 to 1996. In 1996 I won the ICTM Individual Senior State Championship — written precalculus, a perfect 40. I set my sights on MIT after watching the robot competition on television. I got there, and it still feels like the right door.
I arrived intending to be a chemical engineer. One night in a lounge that path opened wider. I did research in the Media Lab, TA'd organic chemistry, and started CampusCraze before the diploma was warm. Fluent in English and Mandarin. Native of Taiwan.
What followed has been a life I love: founder, then CTO, then larger stages — Jenzabar, FreeCause, Rakuten, Amazon, Flexport, Built, Wonder, Immortals. I am also an angel investor and an MIT class officer. People still call me mitnerd. Some still say chenman.

Press
Work that made the page.
It was a joy to be featured in Business Week magazine before I graduated from MIT. In Japan the Nikkei wrote about the Rakuten years — cool technology, a billion lives, a name in world history. Beacon Reports told the CampusCraze and FreeCause story.

The column is titled with that line. Cool technology, at the scale of a billion lives.
