Greenhouse makes move to employee ownership
More than a business decision
On 10 July 2025, Greenhouse became 100% employee owned. After years of working with an amazing community of changemakers with a clear mission to drive social and environmental change, Greenhouse has taken the next step by moving to employee ownership.
The move to employee ownership isn’t just a business decision – it’s the natural evolution of our values and our commitment to practising what we advocate for in the world. We have been a B Corps for 10 years with a firm belief that business can be a force for good, that we value people, planet and profit and that we are here to serve the green movement that we operate in. This next step recognises the extraordinary commitment of our team plus the clear belief that they are the best people to develop and deliver the vision moving forwards.
Why employee ownership matters now
Since founding Greenhouse Communications, Anna Guyer has been driven by a simple but urgent belief that climate change demands not just action, but transformation. Real, systemic change that ensures people and planet can thrive together.
“We’ve built something special at Greenhouse – a team of passionate communicators who see their work as more than a job. We’re a community of changemakers, united by our mission to amplify the voices and solutions our world desperately needs to hear. The creativity that flows through our campaigns, the strategic thinking that guides our client work and the passion that drives us through challenging projects – it comes from all of us, working together,” says Anna.
Employee ownership aligns with our values
Employee ownership feels like the natural next step because it aligns perfectly with everything Greenhouse Communications stands for:
• Justice and equity: If we’re advocating for climate justice in the world, we must model it in how we organise ourselves. Everyone who contributes to our mission deserves a voice in shaping our future.
• Collective power: The climate crisis is too big for individual heroes. It requires collaborative action, shared vision and collective commitment – exactly what employee ownership represents.
• Long-term thinking: Sustainability isn’t just about the environment, it’s about building organisations that can sustain their values and impact over time. Employee ownership protects our mission for generations of changemakers to come.
For us this is all about our values. We’re doing this because we believe the future of business needs to be purpose-driven, collaborative and centred in community. We want Greenhouse to be a place where we grow together now and in the future.

What this means for our work
Our mission remains unchanged: to create positive social and environmental change by supporting those with solutions to address climate change. Employee ownership will amplify our impact.
“When everyone on the team is an owner and a steward of our mission, when every voice helps shape our strategy, when collective wisdom guides our decisions – that’s when we believe we will do our best work,” says Anna.
We will continue to be:
• Entrepreneurial and agile, ready to seize opportunities and innovate for our clients.
• Expert-led, deepening our specialist sector knowledge and expanding our network globally.
• Community-minded, supporting the broader movement for climate solutions.
• Impact-focused, measuring success by the positive change and real-world outcomes we help create.
Our community of changemakers
“What makes this transition so exciting is our people. Our team don’t just execute campaigns – they bring creativity, passion and genuine care to every project. They challenge each other, support one another, and share a deep commitment to our mission,” says Anna.
We have been the business on strong values: we are inclusive, motivated, passionate, authentic, collaborative and tenacious. These qualities drive us every day and will guide us as we grow into this new governance structure.
The future we’re building
“Since the beginning faith has always helped me to focus on justice – climate justice, social justice, economic justice. It’s taught me that we’re called to be stewards of creation and servants of one another. Employee ownership is also an expression of this faith in action,” says Anna Guyer.
As we face the defining challenge of our time, we need organisations that can think long-term, act collaboratively and stay true to their values under pressure. We need businesses that prove there’s a better way to organise human effort toward meaningful goals.
That’s what we’re building at Greenhouse.
What next for employee ownership
The journey will unfold over the coming months, with plenty of opportunities for our team, clients and partners to learn more about what employee ownership means for our work together.
What will change is that we’ll be doing it as a true collective. A community where every member has both voice and ownership in shaping our impact.
What won’t change is our unwavering commitment to the organisations, leaders and movements working for climate solutions. We’ll continue providing the strategic communications support that helps good ideas have big impact.
Special shout out to our partners
To our clients, partners and community – thank you for always being so supportive and for always being alongside us. This step is a commitment to our team and to building something that has a long term role in the movement as we grow together.
We want to thank four amazing employee-owned companies that have inspired us and supported us: Torchbox, The Good Agency, Sawdays and Riverford. They are role models and we are so grateful for their wisdom, time and advice along the way.
It also would be remit to not give a special shout out to Triodos Bank, for being our very first client and also our banking partner for all these years. Triodos bank have guided us and supported us through employee ownership, plus have always believed in and supported who we are and what we do. Special mention also goes to Baxendale, the best employee ownership partners you could hope for, who have kept us on track with knowledge and support on our journey to employee ownership at Greenhouse.
The climate crisis demands transformation. Today, we’re not just advocating for that transformation – we’re embodying it.
