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 brand, to encourage meaningful and lasting impact. We act as advisors and 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 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 organisation’s progress.

Tammy creates this unique, safe space where magic happens. I leave every session motivated and energised!

The thorough focus on sustainability as part of the brand building and the in-depth insights is what helped us create and grow as a brand. Tammy offered us a tailored strategy report that has been crucial to the developing of the brand, she sat with us to understand where we were coming from and what we wanted to achieve and turned it into life. It was a pleasure having her work with our team.

Tammy was amazing! I am starting a brand from 0 and the main challenge is that I want it to be as sustainable as possible.I have been researching for years about this topic and still was as lost and overwhelmed (if not even more) as the first day. During my sessions with Cosie I learned so much! everything started to make more sense and became much clearer, a path I could follow. I am very happy I decided to partner with Cosie on this, I still have a very long way to go but now I have a much
