About

Founder, convener, and impact angel.

I'm the founder and CEO of Socious. I convene the Tech for Impact Summit, grow the Impactism movement, and back founders as an impact angel.

Portrait of Seira Yun

I want to leave my kids — and everyone else's — less to fix, more to build on. Everything else — the company, the idea, the summit, the investments — follows from that one commitment.

For most of modern history we've measured value one way: money. It's legible, liquid and universal — and it quietly bends everything we build toward what pays, not what matters. My work is an attempt to change the yardstick.

I didn't start in software. I spent years in humanitarian management at the International Committee of the Red Cross (ICRC) and UNHCR — close enough to the front lines to see how much human good never shows up on a balance sheet. In 2021 I exited my first social business and founded Socious: infrastructure to make sustainability and impact measurable, verifiable and executable inside real markets.

Make impact, not money, the measure of a life. That's Impactism — not impact translated back into money, but impact honored for itself: conferred between people, and never cashed in.

That conviction grew into more than a company. I proposed Impactism as a way of thinking, founded the Tech for Impact Summit to convene the people who can act on it, and invest as an impact angel in founders working on decarbonization.

It sits in a lineage: Bhutan's Gross National Happiness, Amartya Sen's Human Development Index, and Ken Suzuki's PICSY — each an attempt to measure what money misses. My inversion goes one step further: not a better translation of impact into money, but impact honored, not priced.
