Thanks for joining our collective! We can certainly use your help.
Please use this space to introduce yourself. Where are you from, what do you love doing, how much time you can dedicate to contribute to this collective and whether or not you are already part of a local group for climate.
Looking forward to get to know you!

Starting with myself, I'm Xavier Damman, I'm an engineer in computer science and an entrepreneur now based in Brussels and involved with Extinction Rebellion and #FridaysForFuture. My skills are product development, UX, coding (as in prototyping), fundraising.

I've started Storify back in 2010 in San Francisco where I lived for 7 years (it was a platform for enabling journalists to tell stories using social media, see wikipedia).
I then created Open Collective as a way to help communities collect and disburse money transparently in 2015 and moved to NYC. I now live in Brussels. I have a 7 year old daughter and I've been very active within the Extinction Rebellion movement (I was in the early days of XR Belgium, I participated in the October rebellion in London, got arrested twice already in Brussels) and more recently with the #FridaysForFuture movement.

I now want to dedicate my full attention to the climate emergency. That means helping those different movements for the climate but also helping society prepare for deep adaptation by recreating local communities to increase our resilience. Through my experience with various movements for the climate and citizen initiatives, I realize how much we need to build new software to help them. That's what I want to do, in open source, together and as a non profit.

Hi everyone, I'm Daniel Sum. I am the Co-Founder of Cherry Pulp a digital agency in Brussels and the CTO in charge of the development. I'm also a citizen hacktivist involved in different civic movements like the local currency of Brussels (, the elected civic party that create a deliberative democracy based on sortition ( and many others through our non-profit association

We started a project called an online platform designed to help organizations and individuals to develop, join or finance projects with social impact. 

As a dad, my principal motivation is to boost all the civic movements that can improve the world and potentially solve the climate crisis or the global sustainable goals in order to let a better future for my kid. 

That's why I dedicated all my energy to boost civic projects who will reinvent a new form of organisations and build a better future for everyone. That means helping civic movements and Open-Collective Community in the technical part so they can focus in changing the world - it's clearly my "Ikigai". Every revolutions in the history has been made possible by new disruptive tools. Open Collective Community could definitely be one of them and I'm pretty excited to collaborate in reinventing this new way of collaborating together for a better future.

Hi everyone! 🙌 I'm Michael Hulet and I live in the Belgian countryside. I am the dad of 3 kids aged 10, 8 and 6. They build their own future at l'École Démocratique de l'Orneau. You can find more about me on my LinkedIn profile or by looking at my tweets on Twitter, even if I don't tweet that much. 
I have been involved in my local Transition Town group for a few years, and joined Extinction Rebellion last year, launching a local group, setting up IT services and tools for coordinators and now onboarding a team of rebellious IT enthusiasts. 
I am living the adventure of our time, that Joanna Macy calls the Great Turning: the shift from the Industrial Growth Society to a life-sustaining civilization. This is what I’m dreaming about for years, and we have the opportunity (and we NEED to!) to make it happen. 
I have the feeling that computers can help many follow this path, and the Community project has the potential to make it happen - finally. This is the platform we are all looking for as activists, citizens, neighbours or parents. 
When I’m not coding, I’m on the road to deep adaptation at home and I’m studying to become an edible forest designer. I have the secret project to turn all gardens into delicious food stocks.

Hello hello!
My name is Leen, an energetic woman with roots in Antwerp city, mom of 3 crazy boys, that recently moved to Brussels to put all the energy I have (and I have lots :-)) in citizen projects and movements that catch my enthusiasm. I’m driven by the idea that society should be a warm, dynamic, inclusive and brave environment, where people feel comfortable to actively contribute, connect and care. I have just jumped into the big adventure of working as a professional facilitator, trying to create that environment wherever I can. When I’m not working on that, you find me running in a park, with my nose in a book, or camping in nature with my boys.

The past 7 years I worked in a university college in Antwerp as a policy advisor (on language and powerful learning environments), where I developed a didactical tool to stimulate active participation of students in classrooms and optimize the learning experience for both lecturers and students. 

About two years ago I got bitten by the deep democracy vibe and got very inspired by the facilitation techniques and world views of Myrna Lewis, Arnold Mindell and Margeret Wheatly. I became core contributor to the local and regional citizen list in Antwerp (, trying to revive democracy and working towards a deep (political) system change by focusing on citizen participation and full transparency in policy making (e.g. by organizing and facilitating citizen and people assemblies).

Since last year I have been contributing a lot of my time to Extinction Rebellion, in the Regenerative Culture Circle and the political circle. I see the movement as a big gateway to a new society, questioning deeply the existing laws that destroy our world, ringing alarm bells about the climate emergency, giving us all the chance to experiment with new ways to build a sustainable society and reinvent organizations. 

The biggest challenge for me in this project is how to build a platform that enables initiatives to build strong relationships within the collective and with the bigger community. Nothing beats live meetups and real dialogue to connect and build this new world we need so much. With no experience in IT at all, but as a woman and mother, with two feet in the real world and in activism, I will do my best to make this platform accessible for every busy citizen that wants to build and act without wasting time.

I am madhu singh working in Askmeoffers. is basically a trusted brand and a leader in India's affiliate eCommerce scene. 
That's why I dedicated all my resources to promoting community initiatives that would create a modern organizational model and construct a sustainable life for everyone. This includes supporting social activists and the Open Commons Group on the technological side so that they can work on transforming the environment-it 's my "Ikigai" obviously. Modern transformative technologies have made any change in history possible. Open Mutual Culture may certainly be one of them, and I'm very excited about working together to develop this modern form of working together for a better future.

Life is full of surprises, you will never know what lies ahead. I hope that reading about my experience will help you reflect on your present and your future, and will either help you start your career as a developer or motivate you to move forward in achieving your goals. The process is not a easy job it requires a lot of efforts of designers and developers to develop a end product that stands out in the market.
