About

A small senior team for data too large to copy.

Stratoscale is a boutique geospatial data engineering consultancy. We make petabyte-scale climate, satellite and sensor archives queryable with SQL, directly in object storage — and we build the open-source engine that does it.

It started with one hard problem.

Making petabyte-scale climate and satellite data queryable with plain SQL, without copying it into a database first.

Solving it meant working deep in query engines, storage formats and cloud infrastructure — and that work became zarr-datafusion, our open-source engine.

Today we bring the same skills to teams sitting on large array datasets who need them in front of analysts and decision-makers — without standing up a warehouse or a large in-house data team.

What we believe

01

Senior people do the work.

The engineer you talk to on the first call is the one who builds your system.

02

Working results over slide decks.

We prove ideas with running code and real measurements.

03

Open standards, no lock-in.

We build on open formats and your chosen platforms, so you're never dependent on a vendor — or on us.

04

Your data stays with you.

We work inside your environment, with access you control.

05

Numbers you can defend.

Every recommendation comes with costs, trade-offs and stated assumptions.
