• Develop and execute outbound strategies—including cold calling, email outreach, and social selling—to generate high-value business opportunities.
• Qualify leads based on fit, interest, and potential value to build a high-quality sales pipeline.

• Build and maintain a robust pipeline of engaged prospects through strategic outreach and follow-ups.
• Track all prospecting activities in our CRM (Attio) to ensure accuracy and transparency.
• Work closely with the sales team to optimize lead handoff and improve conversion rates.

• Define best practices and processes to scale outbound sales efficiently.
• Collaborate with leadership to develop hiring and expansion plans for the SDR team.
• Help recruit, train, and mentor new SDRs as the team grows.

• Stay up to date with trends in media, advertising, and digital marketing to inform and tailor outreach strategies.
• Identify new markets and segments with untapped potential.

• Partner with the Director of Partnerships (Australia-based) and the wider sales team to align on strategy and execution.
• Report on key metrics, including lead conversion rates, outbound efficiency, and pipeline health.

Continuously refine outreach techniques based on real-time feedback and data-driven insights.
