Overview

ClearCalcs, a leading provider of engineering computation software, partnered with Whistle to manage rapid growth and an expanding lead pipeline. Known for replacing manual spreadsheets and costly desktop programs with intuitive, cloud-based templates, ClearCalcs reached a stage where increasing inbound interest demanded a scalable, structured approach to sales outreach. Whistle stepped in to streamline lead follow-up, clear backlog trialist lists, and accelerate demo bookings to sustain ClearCalcs’ growth momentum

Challenges Faced

Scaling Demand: A surge in leads left the internal team without the capacity to respond quickly or consistently.

Backlog of Trialists: Hundreds of previous trial users required structured follow-up to identify new opportunities.

Time Constraints: Limited bandwidth prevented the team from balancing outreach with daily operational tasks.

Our Solution

Whistle built a lean, high-efficiency SDR model tailored to ClearCalcs’ immediate growth stage.

Dedicated Appointment Setting
Whistle deployed one full-time Appointment Setter (two SDRs working in alternating four-hour shifts), ensuring consistent coverage and proactive outreach.

High-Volume Demo Scheduling
With structured call blocks and daily reporting, Whistle increased the volume of qualified demo bookings, filling ClearCalcs’ calendars and maintaining strong engagement rates.

Operational Alignment
A shared feedback loop between Whistle and ClearCalcs kept communication clear and goals aligned. Both teams collaborated closely to test, refine, and optimize outreach strategies in real time.

Results Achieved

Meetings Scheduled: 279 meetings scheduled between January and July 2022.

Qualified Pipeline: 218 qualified sales opportunities created, generating a substantial pipeline value of $4,360,000.

Revenue Impact: Generated an estimated $872,000 in revenue, delivering a remarkable 53X ROI.

High Engagement: Achieved an 85% meeting held rate, confirming the high quality and intent of the booked leads.

Efficient Resource Use: Deployed a unique "split-shift" model with one full-time equivalent (two SDRs) to maximize coverage and responsiveness.

“It’s been an incredibly positive experience working with Whistle. The communication is open and upfront, and I especially appreciate that the Appointment Setters are proactive and confident to test and optimize the process.”

Future Outlook

Scalable Growth Foundation: With a tested and efficient SDR model now in place, ClearCalcs has established the operational infrastructure needed to handle increasing lead volumes without overburdening internal teams.

Sustained Efficiency: The success of the split-shift appointment setting approach ensures that ClearCalcs can maintain high engagement rates and rapid lead response times as they continue to scale.

Focus on Core Innovation: By offloading the lead qualification and scheduling process, ClearCalcs’ internal team can dedicate their resources to product development and customer success, driving long-term value for their engineering user base.
