amBrain

amBrain is a Yerevan, Armenia software engineering company building low-latency trading platforms, matching engines and real-time bidding systems in Rust. We have been building software since 2019.

Trading and FinTech
We develop trading terminals and order management systems and integrate them with exchanges over FIX, ITCH, WebSocket and native crypto exchange APIs. We build crypto exchanges (matching engine, wallets, deposits and withdrawals), platforms for proprietary trading firms (evaluation challenges, trading rules and accounting) and algorithmic trading infrastructure (order execution, market data and pre-trade risk controls).

AdTech
We build DSPs, SSPs for publishers, ad exchanges and ad servers with targeting, frequency capping and reporting, as well as event pipelines for impression and click data. We also build ML inference inside the bidder, where the model decides the bid within the auction window.

AI
We deploy private language models inside a client's own infrastructure and connect them to the systems the client already runs, and we build retrieval-augmented generation (RAG) systems. We have taken an LLM integration to production inside a client's FinTech perimeter: extracting and normalising unstructured broker and venue notices — corporate actions, instrument and margin changes — into structured records the trading system consumes.
