Analytics and graphs.
One fast engine.
Rayforce fuses columnar analytics, graph traversal, and recursive queries into one embeddable execution pipeline—built for teams that measure latency in microseconds, not meetings.

One execution model
Stop moving data
between engines.
Relational operators and graph traversals belong in the same plan. Rayforce sees the whole workload, rewrites it together, and keeps the hot path close to the metal.

Rayfall language
Ask complex questions.
Keep the syntax small.
Use Rayfall interactively, embed the C API, or connect through a growing set of client interfaces. Every surface reaches the same optimizer and execution core.

Built as one system
Small footprint.
Serious machinery.
Everything you need to move from raw columns to connected answers—without assembling a second platform around it.

Columnar analytics
Vectorized filters, joins, groups, windows, pivots, and time-series primitives.
Native graph engine
CSR traversal, shortest paths, centrality, communities, WCO joins, and HNSW.
Recursive Datalog
Express reachability and recursive relationships as rules compiled into the same DAG.
Storage that stays open
CSV, splayed and partitioned tables, memory maps, IPC, and block offloading.
Rayforce in the wild
Built for real work,
not synthetic demos.
Rayforce is already part of production systems and open-source projects spanning trading, market connectivity, investment analytics, and risk.
Usage confirmed by the Rayforce project. Consumer names link to their public sites.
Rayforce Cloud Coming soon
The engine you can embed.
The platform you won’t have to operate.
We’re bringing Rayforce’s unified analytics and graph pipeline to a managed cloud experience—so teams can move from local prototype to production workload without rebuilding the data path.
