WE BUILD
SYSTEMS
THAT HOLD.

Raw EVM infrastructure, production AI pipelines, cloud-native backends and the mobile & web products sitting on top. We go where generalists can't.

What we build

OUR FOUR
DOMAINS

Four disciplines. Each one goes deeper than a generalist shop. You work directly with the engineers.

01
01 / 04
BLOCKCHAIN& ONCHAININFRA

Raw EVM log correlation, Substreams pipelines, Subgraph protocols, and high-throughput indexing into ClickHouse and TimescaleDB. The engineering that powers institutional DeFi analytics nobody else gets right.
