About Meridian
Meridian is a family of open-source analytics tools that make messy data approachable. We build software that helps analysts understand what's in their data before they query it — so they can trust what they see and act on what they know.
Why “Meridian”
A meridian is a line of measurement — the reference point navigators use to know exactly where they are. It's also the line the sun crosses at noon, connecting the name to light, clarity, and precision. That felt right for tools built to help you find your bearings in unfamiliar data.
Who it's for
Meridian is for data analysts, analytics engineers, and anyone who regularly opens a CSV and wonders what's actually in it. If you've ever spent an afternoon figuring out which columns are dates, which are identifiers, and which will break your query at row 47,000 — these tools are for you.
Current tools
FineType
A semantic type inference engine written in Rust. Point it at a dataset and it identifies 250+ types — dates, emails, currencies, coordinates, phone numbers — then maps each to a DuckDB SQL expression guaranteed to succeed. One command, no setup, no cloud required.
More tools are in development. Each will focus on a single problem in the analyst's workflow and ship when it's ready.
Built by
Built by Hugh Cameron, based in Australia. I've spent years working with analytics tools — building pipelines, exploring datasets, and trying to close the distance between a raw file and a wonderful answer.
Licence & open source
All Meridian tools are released under the MIT licence. Free to use, modify, and distribute.
Open source isn't just how we distribute the code — it's how we think about the work. Analysts already operate in the open: sharing queries, publishing notebooks, building on each other's findings. Our tools belong in that ecosystem.
Source code, issues, and contributions live on GitHub.
