Arbiter
Decision, safety, and infrastructure for the work that has to be right.
Finance
Arbiter builds decision, safety, and infrastructure for regulated and high-stakes domains: places where being wrong is expensive and someone is required to be right.
Every product is held to the same standard. It has to work under scrutiny, hold up when the record is examined years later, and state plainly what it can and cannot prove.
The company was registered in 2026, after the work was already underway. Each product was researched, engineered, and tested as working software before there was an entity to hold it. Nothing here began as a business plan waiting for a build.
The unifying idea is the same in every domain. Take an ambiguous input, apply the rules, make the call, and keep proof a third party can check.
Leadership
Dayeon Kang
Founder & Chief Executive
I’m the founder of Arbiter, a developer, quantitative researcher, and civic-technology builder. I lead design, engineering, and delivery across all five domains, from the cold-chain hardware thesis to the cryptographic trust rails to the AI-safety research.
My method is the same everywhere: find a place where a high-stakes decision is made badly or slowly, build the system that makes it well, and keep proof it was right.
