The problems
  • Digital marketing didn’t exist yet
    Cold outreach and lead generation were completely new to Climate Clarity. Visibility had come from workshops, event appearances, and organic posts on LinkedIn - enough to spark interest, but without scale or predictability.
  • A Narrow Target Audience to Reach
    Their ideal customers stretch across sectors, from local government through to sustainability teams in the private sector. The difficulty lay in pinpointing and reaching the right professionals with precision and relevance.
  • Scarce In-House Capacity for Outbound
    Being a small, delivery-focused team, Climate Clarity lacked the bandwidth to set up or run cold outreach on their own. What they needed was a partner able to operate the whole system end-to-end.
  • Copy Had to Reflect Their Values
    Sustainability is a purpose-driven field. The messaging had to come across as authentic, non-salesy, and consistent with their audience’s values - while still driving a clear next step.
How we fixed it
  • Built a Custom-Scraped Database of Sustainability Professionals
    We assembled a premium database of decision-makers holding ESG, sustainability, and climate strategy positions across the UK, segmented by organization size, sector, and seniority.
  • Tried several extra ICPs
    With geography as a constraint, we aimed to push Climate Clarity’s reach past sustainability professionals alone - so we tested additional ICPs including HRs, C-levels, Marketing & Comms.
  • Conversation-Starting CTAs That Worked
    Rather than pushing for meetings in the very first message, we requested permission to send prospects personalized Loom videos, which then led to booked calls. Friction dropped and replies climbed.
  • Outreach engine run end to end
    From data and messaging through technical setup and deliverability, our team operated the full outreach system - freeing Climate Clarity to concentrate on conversations rather than campaign operations and management.
The outcome
“The data-driven results B2B Growth Engine.io delivered really impressed me. So did the range of expertise they brought to the project team, plus the sheer scale of outreach they managed to execute.”

Climate Clarity
