Challenges
  • No Digital Marketing Systems
    Climate Clarity had never used cold outreach or lead generation. Their visibility relied on event appearances, workshops, and organic LinkedIn posts, which generated interest, but lacked scale and predictability.
  • Needed to Reach a Niche Audience
    Their ideal clients span industries - from local government to private sector sustainability teams. The challenge was identifying and targeting the right professionals with relevance and precision.
  • Limited Internal Resources for Outbound
    As a small team focused on delivery, Climate Clarity didn’t have the capacity to build or manage cold outreach themselves. They needed a partner who could run the entire system end-to-end.
  • Messaging Needed to Be Values-Aligned
    Sustainability is a mission-driven space. Messaging needed to feel genuine, non-salesy, and aligned with the audience’s values, while still prompting clear action.
Solutions
  • Custom Scraped a Database for Sustainability Professionals
    We built a high-quality database of decision-makers in sustainability, ESG, and climate strategy roles across the UK, tailored by org size, sector, and seniority.
  • Tested Multiple Additional ICPs
    Being limited geographically, we wanted to ensure we expand Climate Clarity’s reach beyond sustainability professionals. So we tested more ICPs such as C-levels, HRs, Marketing & Comms.
  • CTAs That Helped Open Conversations
    Instead of pushing meetings from the first message, we asked permission to share personalized Loom videos with the prospects that led to booking calls. This lowered friction and boosted replies.
  • Complete Outreach Engine Managed
    Our team ran the entire outreach system, from data and messaging to technical setup and deliverability, allowing Climate Clarity to focus on conversations, not campaign operations and management.
Results
“I was impressed by the data-driven impact UltB.io was able to provide. Also, the variety of expertise they offered as part of the project team, and the sheer volume of outreach they were able to deliver on.”
