The data foundation
for the AI era.

An open lakehouse data platform: storage and compute scale independently, every engine works on the same data, and it runs on your own infrastructure — with no vendor lock-in on your data or architecture.

Key architecture

Storage and compute, decoupled.

Traditional clusters put compute and storage on the same nodes: whatever you run short of, you buy whole servers — and data takes three times the space. Use the buttons below to see how scaling differs.

Hare: compute and storage scale independently

Add only what you need
Hare compute layer (SQL / batch, containerized)

Platform

An open architecture — every layer replaceable.

Every layer uses open technology and open formats, connected through standard interfaces. Watch the orange packet travel from applications all the way down to storage.

Many engines, one platform

Data flows in. Insight flows out.

Once data lands in Hare, SQL, batch jobs, notebooks and AI frameworks all read the same data — no more copies for every tool. On the right: one SQL query spanning Hare and an existing database.
