Data quality monitors: the dbt-test layer everyone needs and nobody bought
dbt tests are reactive. The product that proactively monitors data freshness, schema drift, and row-count anomalies, without a giant SaaS bill, wins the dbt-on-Snowflake long tail.
Why now
Monte Carlo and Bigeye sell to enterprise. The mid-market, anyone running dbt on Snowflake or BigQuery for under $50K/yr, has no good tool. The OSS-first product wins by being self-hostable.
The idea you could build today
Connect to the warehouse. Sample tables on a schedule. Detect freshness lapses, schema changes, row-count anomalies, null spikes. Alert to Slack. Free OSS, hosted SaaS for the alert + history.
Build stack
- ·Python core + TypeScript dashboard
- ·Connector library per warehouse
- ·Anthropic Claude for the anomaly classification
- ·Slack + email alerting

The seed-round pattern hiding in the trendline
Data-quality OSS repos with velocity in the "anomaly-detection" module + dbt integration are the seed-stage tells.

What about Monte Carlo / Bigeye?+
Enterprise. The OSS-first, self-hostable, dbt-native version wins the long tail.
