Humbility

By its own account the first large-scale crypto trading firm in Lithuania, which makes Vilnius an improbable node on the European HFT map. Humbility runs high-frequency arbitrage across two worlds at once: centralized exchange order books and on-chain DeFi markets, a dual-venue posture that forces it to maintain custom infrastructure for both standard exchange APIs and live mempool monitoring.

The approach is model-driven and self-contained. The firm gathers large volumes of market data, builds mathematical models tested against real-world simulations, and runs arbitrage bots while also taking directional positions long and short. Teams own both the strategies and the systems beneath them outright. Incorporated in July 2021, it has since added footholds in the United Kingdom and France.
