Building a digital presence for a sustainability challenger
When Infinitas Design and Hillside Environmental Services merged to form HI Group, it marked the start of an ambitious new chapter. With bold plans for growth and innovation in the decarbonisation sector, the newly formed business turned to Whistle to help shape its brand and bring its story to life online.
The Challenge
Emerging from two respected consultancies, HI Group entered the market with broader services, a bigger vision, and a clear mission to accelerate the green transition. But a larger offering meant a more complex message, and it needed to be communicated clearly, consistently, and with confidence.
To succeed, HI Group had to build brand awareness from the ground up. That meant expanding its digital footprint, forging connections with key sectors, and positioning itself as a challenger brand in a space dominated by established players.
The Response
Our partnership began with the people behind HI Group. We led a strategic communications workshop with senior leaders and the commercial team, uncovering the brand’s values, differentiators, and priorities. These insights shaped a detailed messaging matrix and communications strategy, laying the foundation for all external messaging – from press to social.
We then developed a tailored social media approach to reflect the bold, forward-thinking spirit of HI Group. Each channel was assigned a clear purpose and tone of voice, with content themes built to inspire trust, spark conversation, and drive engagement. Backed by a robust 12-month content plan, Whistle took full ownership of the brand’s organic social media, curating, creating and managing content aligned with business goals and audience needs.
The Results
Whistle’s work with HI Group delivered measurable, high-impact results:
- 480% growth in followers on their lead social platform, boosting brand reach
- 68% increase in search appearances, enhancing discoverability
- 277% rise in social engagements, reflecting deeper audience connection
These results helped position HI Group as more than just a new name, they’re now a credible voice in sustainable decarbonisation, driving innovation and change.
At Whistle, we don’t just deliver social media plans, we build platforms for influence. Our work with HI Group shows how strategic communications can help purpose-driven brands cut through the noise, connect with their audience, and amplify their impact.
