About ClearCalcs

ClearCalcs engineering software enables you to replace clunky spreadsheets and expensive desktop software with powerful, easy to understand templates that are quick to export to PDF, and available online with no install.


At the time ClearCalcs approached Whistle, they were at a point where they needed to start scaling. As leads increased, they needed to ensure they had a scalable solution that would enable them to manage the lead process. They also had a massive backlog of former trialists and not enough manpower and time to take advantage of the lead opportunities.


Whistle set up one full time SDR (two SDRs working 4 hour shifts). This SDR team was able to make calls and book demos at a much higher volume than ClearCalcs was previously able to, due to time constraints. This resulted in more demos in ClearCalcs’ calendars and more freed-up time in their days to do the necessary admin and focus on looking ahead.
