AI Agents for Data Analysis

Your data team is backlogged. Every department wants dashboards, ad-hoc queries, and weekly reports. AI agents do the repetitive analysis work so your analysts focus on the questions that actually move the business.

The Problem

A data team of 5 analysts supporting a 300-person org gets roughly 40 ad-hoc requests a week through Slack, Jira, or email. Product wants a funnel breakdown. Finance wants revenue by cohort. Marketing wants attribution. Each request takes 2 to 4 hours because the analyst has to understand the question, find the right tables in Snowflake, write the SQL, validate the numbers against a source system, and paste results into a Looker dashboard or a Notion doc. The queue stretches to 3 weeks. Executives stop asking. Decisions move on gut instead of data. Meanwhile, a third of those requests are the same metric sliced differently: MRR by segment, MRR by plan, MRR by rep. Anomaly detection is nonexistent because nobody has time to set up alerts, so a 12% drop in signups runs for 11 days before finance catches it in the monthly board deck. The bottleneck isn't the data. It's that every question needs a human to translate it into SQL.

How AI Agents Solve It

A Claude Sonnet 4.5 agent connects to your Snowflake, BigQuery, Databricks, or Redshift warehouse with read-only credentials scoped to approved schemas. It ingests your dbt models, Looker LookML, and a curated metric glossary into a Pinecone index so it understands your business definitions (what ARR means in your company, how you define churn, what counts as an active user). When someone asks a question in Slack or the internal app, the agent writes the SQL, runs it with query resource limits, returns results as a table or chart, and shows the SQL for review. For scheduled reports it runs on cron and posts to Slack or email with trend context. For anomaly detection it baselines each key metric over the trailing 90 days and alerts when current values fall outside expected range with dimension-level attribution. Every query writes to an audit log for the data engineering team to review.

How It Works

1

Connect and Map

The agent connects to your data warehouse (Snowflake, BigQuery, Databricks, Redshift, or Postgres) with a read-only role scoped to approved schemas. It indexes your dbt models, Looker LookML or Cube definitions, and a metric glossary maintained by your data team into Pinecone. Schema awareness includes table relationships, column descriptions, join keys, and known grain (daily, session, user). Business definitions (ARR, churn, active user, attributable revenue) are centralized in the glossary and version-controlled. Failure modes: if a metric is undefined in the glossary, the agent refuses to compute it and asks the data team to define it rather than inventing a formula.

2

Query and Analyze

Users ask questions in plain English through Slack, the internal app, or a REST endpoint. The agent rewrites the question using the glossary, generates SQL, runs it against the warehouse with a timeout and byte-scanned cap, and returns results as a table, a line chart, or a breakdown by a requested dimension. For complex questions it will propose the approach first, show the SQL, and ask for confirmation before running. Scheduled reports run daily or weekly and post to Slack with period-over-period context. Failure modes: queries that would scan over a configured byte limit are rejected with a suggested optimization rather than run.

3

Alert and Explain

The agent baselines each monitored metric over the trailing 90 days using a seasonal decomposition model. When a current value falls outside the expected range (default 3 standard deviations), it sends a Slack alert with the metric, the deviation magnitude, the start time of the drift, and a dimension-level decomposition showing which segments account for the change. It then drafts a short explanation (revenue dropped because SMB conversion fell in the enterprise pod, not because prices changed). Your analyst reviews and either confirms or marks as noise, which refines the model. Failure modes: if the warehouse is stale (last load older than 4 hours), alerts are suppressed until freshness recovers rather than firing false positives.

What You Get

Self-serve analytics

Business teams get answers in minutes instead of filing a Jira ticket and waiting two weeks. A product manager asking what percentage of new signups activated within 7 days gets SQL, a result table, and a trend chart in under 90 seconds. The data team stops being the bottleneck on basic questions. For one client, ad-hoc ticket volume fell 88% in the first quarter and analyst CSAT went up 22 points.

Anomaly detection that works

The agent monitors your key metrics (ARR, signups, conversion rate, churn, NPS, cost per lead) continuously and alerts within hours when something drifts outside expected range. No more discovering a 15% signup drop two weeks after it started. Alerts include dimension-level root cause so you see which segment, channel, or cohort is driving the change, instead of only knowing that a number moved.

Analysts do real analysis

Your data team spends time on forecasting, experiment design, infrastructure improvements, and investigating genuinely hard questions instead of running the same weekly revenue report. One analyst at a Series B SaaS company moved from 80% ad-hoc work to 80% strategic project work within 8 weeks of rollout, and the team shipped three major forecasting models they had been unable to prioritize for two years.

Consistent metric definitions

The agent uses your governed metric glossary for every calculation. ARR computed by the CFO query matches ARR computed by a PM in Slack. No more conflicting numbers from different teams running different queries with slightly different filters. When a definition changes (say, you stop counting non-paying trials in active users), it updates in one place and every downstream report reflects it the same day.

Human in the Loop

Data engineers review any generated SQL before it becomes a recurring scheduled report or a saved query. Ad-hoc user questions run without review because they're read-only and resource-capped. Anomaly alerts require analyst confirmation before escalating to business owners. Any metric not defined in the governed glossary routes to the data team for definition rather than being computed on the fly. Queries above the byte-scanned threshold (default 50GB) require manual approval. All guardrails and thresholds are configurable per schema and reviewed monthly with the data platform team.

Frequently Asked Questions

Does the agent write SQL directly?+
Yes. It generates SQL based on your schema, your dbt model definitions, and your metric glossary, runs it against the warehouse with a read-only role, and returns results. Every query is visible to the user who asked, logged for the data team, and saved as a reusable artifact if marked. For complex multi-step analysis, the agent shows its plan and the SQL before running so you can catch issues upfront. Your data team can review and amend the agent's SQL the same way they would a junior analyst's work. We have seen the agent write cleaner SQL than most junior analysts within 4 weeks of deployment because it has full schema context.
What if the agent writes a bad query?+
All queries run with read-only permissions and two guardrails: a 120-second timeout and a configurable byte-scanned cap (default 50GB per query). If a query would exceed either, it's rejected and the agent proposes a more efficient formulation (add a date filter, aggregate first, use a pre-built rollup table). The warehouse role cannot drop, update, or insert, so a bad query cannot corrupt data. For Snowflake specifically, we use resource monitors to cap credit consumption per user. Queries that return unexpectedly large result sets (over 100K rows) are paginated or summarized automatically rather than dumped to the user.
Can it handle complex multi-table joins?+
Yes. The agent understands schema relationships from your dbt manifest or LookML and writes joins with appropriate grain management. It handles window functions, CTEs, subqueries, recursive queries, and semi-structured data (JSON, VARIANT in Snowflake, STRUCT in BigQuery). For questions that require joining 5+ tables or multiple CTEs, the agent will break the work into intermediate steps and show each one for review. It knows about common anti-patterns (fanout from one-to-many joins, duplicate grain) and will warn when a join would produce misleading counts. If your schema is a mess, the agent will surface that rather than produce garbage silently.
How does anomaly detection work?+
The agent learns normal patterns for each monitored metric using a seasonal decomposition model over the trailing 90 days (Prophet or a custom STL approach depending on the metric). When a current value falls more than 3 standard deviations outside the seasonal-adjusted expected range, it fires an alert. The alert includes the magnitude of deviation, the time it started drifting, and a decomposition showing which dimensions contributed (by channel, segment, cohort, geography). Your analyst reviews and either confirms the anomaly or marks it as noise. Marking as noise refines the baseline. For metrics with irregular patterns (daily signups with strong weekday seasonality), the model adjusts automatically. For new metrics with less than 30 days of history, alerts stay off until the baseline is stable.
What happens when the agent isn't sure? Does it just guess?+
No. For questions with ambiguous scope (what does active user mean here, which revenue definition), the agent asks a clarifying question before running. For questions about undefined metrics, it refuses to compute and asks the data team to add a definition to the glossary. For queries that return suspicious results (impossibly round numbers, unexpected nulls, grain explosion indicators), the agent flags the result with a warning rather than presenting it cleanly. Confidence is surfaced to the user: high confidence results look normal, medium confidence results come with a warning about caveats, low confidence results route to the data team for validation before the user sees them.
How does it integrate with our existing BI tools?+
We connect to Looker, Tableau, Mode, Hex, and Superset as read sources for existing dashboards and as write targets for new ones. For Looker, the agent uses LookML as part of its schema understanding and can generate new Looker explores or dashboards through the API. For Tableau, it writes back computed datasets through the Tableau Server REST API. The goal isn't to replace your BI tool. It's to shorten the time from business question to usable answer. Users still consume long-lived metrics in dashboards. The agent handles the questions dashboards weren't built for and the requests that would otherwise queue with the data team.
How is this different from Looker or Tableau's built-in AI features?+
BI-native AI features are limited to the data model already defined in the tool. Looker's assistant can query what's in LookML. Tableau's can query what's in the data source. Our agent operates one layer higher: it spans your warehouse, dbt models, BI semantic layers, and a company-wide metric glossary. It can answer questions that require joining across datasets the BI tool doesn't have wired together yet. It also handles scheduled reports, anomaly detection, and Slack-first delivery, which most BI AI features don't. In practice, most of our customers keep Looker or Tableau for dashboards and use the agent for ad-hoc analysis, alerting, and questions that cut across domains.
Can we audit every decision the agent made?+
Yes. Every question, every generated SQL query, every execution plan, every result, and every user who saw it writes to an audit log in Postgres. Your data engineering team gets a daily digest of agent activity: volume, top queries, resource consumption, result accuracy feedback from users, and metric definitions referenced. Query patterns that repeat frequently get flagged as candidates for promotion to a dbt model or Looker tile. This feedback loop is important because the agent should reduce data team load, not create a shadow analytics layer. Audit logs retain for 13 months and are queryable by user, by metric, by dataset, or by time range.
