60 day lookback
Identify tables unused over 30, 60, or 90 day windows. Find the real dead weight.
Data stays secure
Your data never leaves your warehouse. We query metadata only, never table contents.
You know there is waste. You just cannot find it fast enough.
You are paying Fivetran to sync hundreds of tables into your warehouse, but half of them have not been touched in months. Every unused table costs you Monthly Active Rows. Digging through INFORMATION_SCHEMA to find them is a day's work you never get round to.

From connection to savings in under 5 minutes.

We find the dead weight
Optimisely queries your audit logs to find Fivetran tables that nobody has touched in 30, 60, or 90 days and calculates their MAR cost.

Common questions
How does Optimisely cut Fivetran costs?+
We connect to your warehouse, identify Fivetran-synced tables that have not been queried recently, calculate the Monthly Active Rows cost of each unused table, and show you exactly which connectors to disable.
Is it really free?+
The initial analysis is free and takes about 5 minutes. You only pay if you want ongoing monitoring and automated recommendations.
What warehouses do you support?+
Google BigQuery and Snowflake today. Databricks and Redshift are on the roadmap.
Do you have access to my data?+
No. Optimisely only needs read access to INFORMATION_SCHEMA and audit logs. We never query the contents of your tables.
How much can I save?+
Most teams find 30 to 50 percent of their synced tables going unused. On a 2,000 GBP per month Fivetran bill, that is typically 600 to 1,000 GBP of recoverable spend.
