Diagnose, never write
Read-only credentials, and no fix is ever attempted. Sentry tells you what it found and hands you the evidence; the decision stays yours.
Sentry is made by Sovarium in London, for the data teams that owns a warehouse everyone else's decisions run on.

I spent six years leading analytics at fast growing startups where people relied on the numbers in dashboards to make decisions. I would find out about broken data from someone forwarding a dashboard and asking why the number looks wrong.
We had some tests in place but at a startup things move fast and the tests would go out of date quickly. Maintaining them takes too long and there was always something more urgent on the roadmap.
The tools that fix this properly are built and priced for companies a hundred times our customers’ size. So I built the one I wanted priced for regular sized data teams.

Four commitments that decide what gets built and, more often, what does not.
Read-only credentials, and no fix is ever attempted. Sentry tells you what it found and hands you the evidence; the decision stays yours.
If it needs a threshold you had to guess, we have pushed our work onto you. Sentry learns each table's normal from its own ninety days of history.
An alert nobody reads is worse than no alert. Every feature has to survive one question: does this make the morning digest more worth opening?
Self-serve pricing on the page, no sales call, no seat games. The one-to-five person data team is the customer, not an afterthought.
A pipeline stops loading. An upstream API changes a field format. A join starts fanning out duplicates. Nothing crashes, no error is raised, and the numbers are simply wrong.
The platforms that solve this were built for enterprises, and they are priced, sold and installed accordingly. So a small team writes a handful of dbt tests, means to write more, and never gets to it.
Something that learns each table's normal behaviour from its own history, runs every night without being asked, and says what changed in plain English before anyone else notices.
