Low-latency AI solutions for trading and AdTech platforms in Rust
Overview
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.
What clients say
Every review is verified through Goodfirms before it's published.
What reviewers mention most
“At the edge of technologies and high responsible team.”
If you need highly client oriented tech partner that is Ambrain. Responsible, high sophisticated and enthusiastic team. I've never heard something like "this is not our problem". Real partnership, not just outsource.
“amBrain covered a Rust request that most of our network could not, with an engineer who was as senio”
We work with many software companies and notice quickly when things go wrong. This engagement didn't. We approached amBrain specifically for Rust expertise, and that's exactly what they delivered. The engineer asked thoughtful questions in the first few weeks, then took ownership of the project and ran independently. He stayed through completion without any issues surfacing to us—in our experience, that silence is the strongest signal of success. Their team responded to questions the same day most of the time, and when we sent a request outside their wheelhouse later on, they were honest about it not being a fit rather than stretching to fill the slot. We'd go back to them for Rust work.
