Your AI is guessing.
Because your data never told it the truth.

We hand-build a verified semantic layer for your business, so every AI agent understands your data like your best analyst does. Built by humans. Checked by humans. Nothing automated.

The semantic layer is fast becoming the standard interface between enterprise data and AI, the layer that decides whether your agents answer with the truth or a guess.

The problem

You bought AI. So why does it keep getting your business wrong?

Confident, wrong answers

It picks the wrong column and tells you the number with total confidence. You only find out in the board meeting.

Every team has a different truth

Finance, sales and ops each define a metric differently. Your AI inherits all three, and blends them.

Tools nobody trusts

The shiny copilot gets quietly abandoned after the first bad number. Trust, once lost, doesn't come back cheap.

Knowledge stuck in one head

The one analyst who knows what the numbers really mean is your bottleneck, and your flight risk.

The hidden cost

The problem isn't your AI. It's that your data can't explain itself.

The solution

A semantic layer is the translator between your data and your AI.

A verified dictionary and map of your data: what every metric means, which tables to trust, how to calculate it, so your AI answers like a senior analyst instead of guessing.

The differentiator

Automatic tools guess at meaning. We don't guess.

Auto-tools infer meaning from column names, so they inherit the exact ambiguity you're trying to fix, at scale. We build every layer by hand, capture your team's real logic, and a human verifies each definition.

What you get

Everything you need to trust a number again.

A version-controlled semantic layer, living in your environment.

Every metric documented: definition · formula · source · owner · verified sign-off.

Live connections to your LLMs / agents, BI and warehouse.

A data-truth audit report: the conflicts you didn't know existed.

Team enablement: documentation plus hands-on training.

An optional ongoing verification retainer.

The bar we build to: when your AI gives an exec a number, nobody opens a side spreadsheet to check it. That's the whole game.
Our promiseEvery number, traceable to a verified definition.

Who it's for

If your AI touches internal data, this is for you.

Teams rolling out AI copilots / agents on internal data and hitting trust issues.

Data teams with drifted metric definitions across departments.

Leaders who want AI-ready data without a six-month rebuild.

Mid-market → enterprise on Snowflake, BigQuery or Databricks.

Not for you if you have no warehouse yet, or you're happy letting AI guess.

FAQ

The questions a data buyer actually asks.

A tool generates a guess from your column names, inheriting the ambiguity you're trying to fix. We capture your team's real logic and a human verifies every definition before your AI ever sees it.

Discovery is about one week. A working, connected layer lands in weeks, not quarters. Fixed-scope, so you know what you're getting.

No. It's built in code, in your stack, and fully handed over. The retainer is optional, you own everything.

Snowflake, BigQuery, Databricks, dbt, Cube, and any LLM or agent. The semantic layer is the neutral source of truth they all read from.

The layer lives in your environment — we don't move your data out of it. We work under your NDA and access controls, request only least-privilege access for the duration of the work, and hand everything over in your own repositories. More detail on our security page.

Stop letting your AI guess. Give it a source of truth it can't get wrong.
