SaaS Spend Anomaly Investigation Agent
When a Stripe charge exceeds a vendor's historical baseline, an agent investigates the spike using Snowflake history and web research.

What it does
Turns a spend spike into a worked investigation, not just an alert. When a Stripe charge comes in materially above a vendor's trailing average, an agent gathers the vendor's billing history from Snowflake, researches whether the vendor recently changed pricing, and writes up the most likely cause with a recommendation.
When to use it
Use it when a raw threshold alert is not enough and you want the first pass of analysis done before a human looks. It is ideal for finance teams who want every unusual software charge triaged with context, separating real price increases from seat growth or duplicate billing.
How it works
- 1A Stripe webhook fires when a charge exceeds the vendor's baseline.
- 2The agent queries Snowflake for the vendor's trailing 12-month charge history.
- 3It runs web research to check for announced price changes or plan migrations.
- 4The agent reasons over the evidence to classify the spike as price increase, seat growth, duplicate, or unknown.
- 5It drafts a recommended action and opens a Linear ticket assigned to the budget owner with its findings attached.
