Tap into the value of data. Go from:

Data locked away

Valuable datasets trapped in static files, unusable by applications

Weeks of development

Building data pipelines and APIs traditionally takes extensive engineering resources

Isolated datasets

No easy way to combine, enrich, or transform data from multiple sources

To unleashing the value from any data file, all spreadsheet exports, and every public dataset in your applications within seconds.

No backend development required.

Case study: Scottish Energy Performance Certificate (EPC) data

Scotland publishes energy performance certificate data as CSV files only. So we used tap to transform those CSVs into the API behind epcdata.scot.

Raw government data

From a zip of 18 CSV files totalling 7.17 GB

Beyond ELT

We cleaned, transformed and enriched it with geospatial indexes

Enabled live applications

Our API is used in numerous applications providing real value
