Target Persona

Veremark is a global background screening and pre-employment verification platform helping companies hire faster and more safely through automated, compliant, integrated checks. The company generates strong inbound demand but lacked a consistent outbound cold-calling cadence, as its Account Executives were too stretched by inbound volume to sustain outreach. Veremark engaged Whistle to provide outsourced SDR talent under a Plug-and-Play model, integrating directly into Veremark's own systems to build outbound coverage across the UK, Australia and Singapore.

Challenges Faced

  • Strong but volatile inbound traffic left Account Executives too tied up to maintain steady outbound activity
  • "Scar tissue" from a previously failed fully managed agency contract made Veremark cautious about outsourcing again
  • Existing Philippines-based SDRs were focused on email and LinkedIn only, with no coverage for phone-based cold outreach
  • An extensive HubSpot database (one SDR alone holding 30,000 contacts) was not being actively worked via cold calling

Our Solution

  • Build a consistent outbound cold-calling cadence to complement existing inbound demand.
  • Assigned 1 SDR to to EMEA warm leads, including webinars and blog downloads.
  • Assigned the other SDR to cold leads.
  • Establish SDR coverage across three time zones: UK, Australia and Singapore.
  • Stay within budget constraints.

Results Achieved

16 meetings scheduled in the first month of the campaign with 10 sales opportunities created.

Future Outlook

As performance data accumulates by source, Veremark and Whistle are positioned to double down on what's working — webinar-driven leads and the reps performing best against them — while adjusting the approach for lower-intent segments.

Key Learning

Lead Source Matters

Webinars and physical events generally produce better opportunities than cold or content-download lists

Focus on SDR strengths

Email-heavy approaches work better for reps who are less effective on calls

Marketing and SDR Alignment

Better targeting, webinar quality and lead qualification directly affect what SDRs can convert
