Cosie is a creative change agency helping you integrate sustainability and purpose into your brand or business.

Whatever your starting point, we work with you to clarify and develop your ideas, build a sustainable vision, and map out a clear and accessible way forward.


Combining our expertise in sustainability with creativity, strategic thinking, and a deep understanding of your needs, we work together to flesh out your brand, integrating sustainability in a way that is accessible for you and aligns with your values and goals.


- Those looking for support bringing your ideas to life, in the form of a tangible vision and direction.

- Entrepreneurs and small business owners wanting to integrate sustainability and purpose into your new or existing brand.


Because we believe that sustainability isn’t simply ‘nice to have’ - it’s essential, both in terms of our collective responsibility, as well as business strategy.

By empowering our clients to be change agents in their industries, we build a network of positive impact and sustainable development.

Sustainability is a buzzword

We hear it all the time, and yet it can feel like a minefield.

We clear up the confusion so you can understand:

how to develop a clear vision and core brand values, with sustainability and purpose woven in seamlessly

how to identify your priorities and drive action from there in straightforward, manageable steps

In other words, we’ll help you get comfy with sustainability.

What do we mean by Sustainability?

Our mission is to make sustainability accessible to entrepreneurs and small businesses owners from various sectors and industries, activating an ecosystem of positive change and impact, from the ground up.

Rather than quick fixes or one-size-fits-all solutions, we help you integrate sustainability in the roots of your business, to encourage meaningful and lasting impact. We act as advisors and creative partners, equipping you with the knowledge, tools and insights most relevant to you to begin and scale up your journey in sustainability.



We start by taking the time to hear from you, understanding your specific requirements, ideas and goals.

In a series of bespoke sessions, we co-create solutions and structure them into an action plan with clear next steps and measurable outcomes.



Here is where we put the formulated solutions and their plans into action.

Depending on your needs, we’ll decide what level of support is appropriate for you to execute and manage your plans with ease.



Plans have been implemented, what happens next? We build a framework to stay in check with the actions and solutions we’ve created together.

We support you in tracking, measuring, reflecting and adapting the solutions and plans according to your progress.

Her skills in design thinking, strategising and brand ideation are extremely valuable for any company or organisation wanting to take things to the next level
