From NYSE to Streaming OS

AlgoX2 was founded by the team that built NYSE Pillar — the trading architecture that today powers $100B+ in daily transactions across 7 regulated exchanges. While building exchange infrastructure, they discovered that no streaming platform could meet the requirements. AlgoX2 is the general-purpose streaming OS they wished existed.

Why AlgoX2

Today's stack vs. AlgoX2

Today's stack

AlgoX2

Rebalance storms stall writes

A single slow consumer — or one added broker — triggers multi-second rebalances that pause production across the cluster.

Partition-free user API

No Kafka-style topic partitions to rebalance. Producers publish to a single stream; X2 handles ordering internally.

Storage coupled to brokers

Scaling disk means adding CPU you do not need — and vice versa. Capacity planning becomes a guessing game.

Compute-storage separation

Scale CPU and I/O independently with policy-driven tiering across NVMe and object storage.

Five systems duct-taped together

Kafka for transport, Flink for transforms, Connect for sinks, Schema Registry for types, Redis for state. Five things to deploy, monitor, and page on.

One unified data plane

App-app, app-storage, and storage-app handled natively in one engine. No connectors, no schema registry, no external state store.

Duplicate pipelines for analytics

Streaming goes one place, analytics queries go another. Data is copied, freshness lags, and infra bills double.

Streaming + analytics in one engine

Kafka-compatible delivery with inline transforms and enrichment. Query the same data you stream.

JVM pauses and kernel copies

Garbage collection spikes tail latency; every hop copies buffers through the kernel. Microsecond tails are out of reach.

Zero-copy, kernel-bypass runtime

NUMA-aware networking with no kernel transitions. Predictable microsecond tails at extreme throughput.

N×M fan-out tax

Delivering one message to N consumers costs N× egress and N× broker CPU. Scaling subscribers scales your bill linearly.

Native multicast fan-out

One write serves thousands of consumers, with no duplicate network or CPU work.
