AlgoX2

AlgoX2 builds a data streaming operating system that unifies ingestion, ordering, fan-out, transformation, and durable storage in one fault-tolerant engine. The company was formed by the team behind NYSE Pillar, the exchange trading architecture, after that team found no streaming platform that met exchange requirements and built the general-purpose streaming system it wanted to exist. It sells infrastructure software that speaks Kafka, NATS, MQTT, Redis, Postgres, HTTP, and WebSocket natively.

AlgoX2 builds streaming infrastructure for exchanges, trading platforms, and prediction markets. It differentiates on native multicast fan-out, where one write serves thousands of consumers. The system covers exchange matching, market-data distribution, risk surveillance, real-time lakehouse loading, strategy backtesting, and AI feature streaming.
