Leading companies trust Sweep
Sweep allows us to have more confidence in our data. It’s extremely simple. The biggest gains so far have been saving time, and no longer necessarily needing assistance from external consultants, because the tool itself brings so much clarity to the process.
Sweep has allowed us to save time and energy. We can focus much more on data quality, instead of discussing how to collect the data. Previously we had dozens of spreadsheets all over the place, but now we have won back all of that time
The positive transformation of our company relies on our ability to make the analysis of our ESG performance just as solid and rigorous as the measurement of our economic and commercial performance.
“We know that the data in Sweep is accurate, enabling us to report information to external partners at the click of a button.”
