Building open source data infrastructure for the context era.For data engineers, by data engineers.

Galaxy is an applied data engineering lab. We build open source data infrastructure, and we join your team to put it to work. Our engine, Filament, moves data from your databases, SaaS tools, and file storage into your warehouse at up to 2.6 million rows per second. Our engineers build the layer around it. One place where all your data lands, one definition of every business term, and one set of rules for who can see what. Your dashboards, your product, and your AI agents all read from the same model.

Filament is Galaxy's open source data movement engine. It copies data from your databases, apps, tools, and file storage into your warehouse or lake, as a full load, just the changes, or a live stream. Every batch is verified on both ends, and a failed run picks up where it left off. It runs on your own infrastructure with nothing metered and no paid tier. In our published benchmarks it finished first against every tool we tested, using less memory and less CPU. Managed ELT charges you the most right when you succeed. Filament costs the compute you already run.

Enterprise context management is how a company turns everything it knows into something its people and its AI agents can trust. Your data lives in databases, your process lives in apps, and your knowledge lives in docs and in people's heads, and they rarely agree on what a customer actually is. Context management pulls all of it into one living model of the business that you control. Every term is defined once. Every record is matched across systems. Every fact carries its history. Every person and every agent sees only what they should, and any action that writes back is checked against your rules first. Get this layer right and your AI is right. Skip it and your AI is guessing.

Galaxy is an embedded applied data engineering team. Senior engineers join your team and help you build the data stack that sets you up for what comes next. It starts with a real problem. A data bill growing faster than the business. A warehouse that needs standing up. An AI agent that answers confidently and wrong. We get the data in, give it one model the whole company agrees on, put rules around it, and ship it as pull requests your team reviews into your own cloud. Working software lands in weeks, not quarters, and your team can run it without us because they built it with us. Email hello@getgalaxy.io to talk to an engineer.

We build on your stack, so we play by your rules. Everything runs in your cloud, under your access controls, your network, and your compliance program. Your data stays in your accounts, and nothing ships without your team's review. Your security posture stays exactly what it already is. What we build is secure by default, with row-level access and audit trails from the start, so every agent stays inside the permissions you set and leaves a record you can check. You own the keys, the code, and the paper trail.

Because your company's knowledge is your most valuable asset, and the infrastructure that holds it should not be rented, billed by the row, or locked in a format that makes leaving expensive. That kind of pricing punishes growth. Good infrastructure should make you want to move more data, not less. So Filament is Apache 2.0, one repository, nothing gated, and every benchmark ships with the code so you can rerun it. No black box, no vendor lock-in, no penalty for growing. Galaxy was built on open source, and we return the favor by releasing each piece of our context management system as it matures. Filament is first.
