About

A fund built like infrastructure.

T0 Systems started from one conviction: the firm that moves from idea to production with the least friction wins, whatever the strategy. Today it is run by its founder.

Our story

Why T0 exists.

I started learning programming on my own at 12 or 13. It was not taught at my school, so I studied it myself and later joined an online engineering school for mathematics, programming and AI.

Each step went deeper. I built small AI models and chatbots, then games in Java, then freelance web projects. Backend work led me to architecture, performance and scalability, where designing an efficient system turned out to be more interesting than building one more application. To understand how software runs close to the hardware, I wrote a small 32-bit operating system in C and Assembly.

In parallel I taught myself economics and finance, tutored university students in economics, and focused on cryptocurrency markets. The tools available to traders had real limits, so instead of using them I built the infrastructure I wanted. That became T0 Systems and its first product, T0 Trading Terminal.

The name says what we care about. T0 is the moment a measurement begins, and every decision in the firm is made to keep that measurement honest.

The name and the mark

Origin, rigor, permanence.

The zero instant

T0 is the starting instant: the origin from which everything is measured. It stands for numerical rigor.

A zero with a bar

The zero carries a diagonal bar so it can never be mistaken for the letter O. Precision starts with the characters.

The shield

Custody and permanence. A solid, symmetrical form with no ornament: an institution that does not depend on fashion.

People

Who runs T0 Systems.

T0 Systems is a one-person firm today. The systems are designed so that human effort becomes reusable capability, which is how one person can run the work of a larger team.

Eichi Arakaki

Founder and developer

A self-taught engineer who builds trading infrastructure end to end, from low-level systems to the market.

Background

  • Age 12–13

    Self-taught programming

    Began learning technology independently, then enrolled in an online engineering school for mathematics, programming and AI.

  • Early

    AI and mathematics

    Studied mathematics to roughly university level and built small AI models and chatbots.

  • Next

    Game development

    Learned Java and applied mathematics and programming to small games.

  • Then

    Web and backend, freelance

    Took freelance web projects, which led to backend engineering and a focus on architecture, system design, performance and scalability.

  • Then

    Low-level systems

    Worked in C and Assembly and built a small 32-bit operating system to learn memory, system architecture and how software runs near the hardware.

  • Alongside

    Economics and finance

    Studied economics and finance independently and worked for several months as a freelance economics tutor for university students.

  • Later

    Crypto markets and trading

    Gained hands-on market experience and saw the limits of the existing trading infrastructure.

  • Today

    Founder of T0 Systems

    Sole founder and developer. Designed and implemented the core architecture of T0 Trading Terminal personally.
