About eMoment
Financial infrastructure engineering, from Tokyo to the world
Our Story
Founded in Tokyo, eMoment Technology (eMoment Japan KK) was built by engineers who spent years inside trading firms, exchanges, and fintech startups. We saw firsthand how critical infrastructure decisions — the ones buried deep in the stack — determine whether a financial product succeeds or fails.
Today, we bring that operator experience to every engagement. Whether it's a greenfield crypto exchange, a latency-sensitive HFT system, or an AI-driven risk engine, we build the infrastructure that institutions trust with real capital.
Our Mission
To engineer financial infrastructure that is fast, secure, and built to last — giving institutions the technical edge they need to compete in global markets.
Our Team
Engineers, quants, and systems architects with deep domain expertise in financial markets and distributed systems.
Global Reach
Headquartered in Tokyo with infrastructure deployed across NY4, TY3, and major cloud regions worldwide.
Our Values
Precision engineering, radical transparency, and relentless focus on correctness.
Engineering Principles
Performance First
Every microsecond matters. We profile, benchmark, and optimize relentlessly — from kernel bypass networking to lock-free data structures.
Reliability
Financial systems can't go down. We design for fault tolerance, graceful degradation, and zero-downtime deployments.
Security
Defense in depth from the network layer to the application. HSM key management, mTLS everywhere, and regular penetration testing.
