## What the story says

Whatnot uses Hex as the environment where analysts and data engineers do exploratory analysis, explore models and prepare forecasts, alongside dbt for modeling and documentation. Once a model is validated, the logic is pushed to dbt, so SQL is shared across analytics, machine learning and data engineering.

Summary written by usedby from the source page, in English. The figures are those of Hex and Whatnot, not ours.

> Analysts and data engineers use Hex as an exploratory internal development environment. They explore models, prepare forecasts, and share findings with each other. Once they confirm the model is solid, they push the logic to dbt.

- **10x**: “10x decrease in maintenance costs”
- **1 week**: “1 week for new analytics engineer hires to start shipping”
- **20x**: “20x growth in sales last year alone”

> dbt and Hex make the data development environment so much easier to work with than any other combination of tools. Since it’s all native, we don’t need to wait for or build a custom adapter
