Cosie up

Cosie stands for co-creative, sustainable, ideas and endeavours. 

We’re on a mission to co-create solutions with you and alongside you, tailor made for you.

We work in non-linear phases that rely on feedback loops while creating space for flexibility. Our approach allows us to think in systems while being adaptive to change. 



Here is where we take the time to listen and understand you and your needs. 

Through a series of sessions together, we formulate co-created 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. 

We support in setting you up for your plans to be executed and easily managed. How much we support you in this phase is according to your needs and is something that we decide together.



Here is where we create space to remain accountable to the solutions and plans that we co-created together. 

We support you in tracking, measuring, reflecting and adapting the solutions and plans according to the current state of your organisation’s progress.

I honestly love working with Tammy! From diving deep -having personal chats where one opens up during dream mapping sessions- to setting intentions and building a whole professional business canvas. Tammy creates this unique, safe space where magic happens. I leave every session motivated and energised!

Through Tammy’s engaging workshops & in depth knowledge of branding & sustainability, we designed a purpose driven brand that I’m truly aligned with. She listened to my vision & challenged my ideas, helping to take concept to the next level. I really feel that she was as passionate & excited about the brand as I was, giving me the confidence in her & in us as a team.
