XAVIER
Trusted answers from data you control
Xavier is Xephyr's analytics agent. It answers questions and runs the analysis inside your environment, under your governance.
WHY XAVIER IS DIFFERENT
Lead with the numbers
- 98%+
Accuracy
98%+ accuracy, measured in production evaluation.
- 5x+
Fewer tokens per question
Fewer than a tier-1 cloud-native platform, from context optimisation. On the hardest questions, up to 75x.
- Open-weight
Cheaper again on open-weight models
Xavier is model-agnostic. On self-hosted open-weight models (Nemotron, Kimi, gpt-oss) you pay for compute, not vendor per-token markup.
- <2 wk
Time to live
Under 2 weeks, because Xavier is pre-configured with your domain context.
- Stable
Predictable
Xavier does not spin into endless loops the way a general LLM agent can, so cost and latency stay stable question to question.
- Yours
Where it runs
Inside your environment, on-premise or private cloud.
WHAT XAVIER DOES
Answers on demand, without the queue
Business teams wait days for answers that sit behind a data backlog. Xavier removes the queue. Ask a question, get the answer, the working, and the source, in minutes.
Does the analysis
Xavier runs multi-step analysis end to end, not just a single lookup. It acts, it does not just chat.
Explainable by default
Every answer comes with its working and its source, so the result is auditable.

FAQ
Common questions about Xavier
What is agentic analytics?
Agentic analytics is AI that does the analysis, not just the charting. Xavier answers a business question end to end: it reads your data, runs the analysis, and returns the answer with its working and its source. It moves analytics from a queue of dashboard requests to answers on demand.
Where does Xavier run?
Inside your environment. Xavier deploys on-premise or in your private cloud, so your data never leaves your control. Your governance rules apply to every query it runs.
Which data systems does Xavier work with?
Xavier connects to Snowflake, Databricks, Google BigQuery, Amazon Redshift, ClickHouse, Oracle, Microsoft SQL Server, PostgreSQL, MySQL, MongoDB, Apache Cassandra, Elasticsearch and Apache Kafka. It reads from what you already run, in your cloud of choice or on-premise, rather than forcing a migration. If your system is not on that list, tell us what you run and we will confirm.
Is my data used to train someone else's model?
No. Xavier runs inside your environment and your data stays there. It is not sent to a third-party model provider for training, which is the core of what sovereign AI means at Xephyr.
How is Xavier different from a BI dashboard tool?
A BI tool shows you data and waits for someone to build the report. Xavier answers the question directly, builds the view, and runs the analysis, so your team stops waiting behind a data backlog. It returns the query and the source alongside the answer, so the result is auditable.
How do we get started with Xavier?
Book a demo and we will show Xavier answering a real question from your world. From there, the usual path is a scoped pilot on one part of your data before wider rollout.
