Let’s reinvent our organisations
to move from depletion
to regeneration
Our organisations were designed to optimise and grow. They must now learn to adapt if they want to last.
In a world marked by ecological limits, instability, and a loss of meaning, the question is no longer simply about reducing negative impacts.
It is urgent to fundamentally transform the way we operate, in order to regenerate the people and ecosystems on which we depend.
Join us at
ChangeNOW 2026 !
We will be at ChangeNOW, on March 30th, 31th and April 1st in Paris to explore concretely what it means to regenerate an organization, and to become regenerative. At our booth, you will be able to:
- discover our approach,
- experience our new ReSet game,
- discuss your strategic challenges,
- and question what regeneration actually changes within an organisational framework
Come and meet us and enjoy a 30% discount at this dedicated fair focused on solutions!
Our promise at ReGen by Nexus
What is required is a shift in mindset: drawing inspiration from living systems to create an organisation capable of adaptation, cooperation, and renewal. In order to strengthen both the vitality of its members and the health of the ecosystems on which it depends.
ReGen by Nexus accompanies you to operate this shift. Through engaging at strategic, cultural and operational levels, we help leadership teams and their organisations integrate the principles of living systems into their operations, decisions, business models and governance methods.
Who we are
Founders of Nexus in 2005, Silvia Gollini et Matthieu Daum have been supporting the regeneration of companies since 2015, and subsequently created a model of the 6 Principles of Regeneration.
What we offer
ReSet Workshop
ReSet is a collaborative game, at the same time dynamic, playful and profound, which enables organisations to enter the mindset and the functioning of living systems, in order to regenerate themselves and become regenerative.
Through play, teams produce concrete solutions for positive impact, both internally and externally.
Regenerative Leadership Training
Whether it’s to sustain regenerative solutions that emerged from ReSet, or more generally to breathe new life and a new dynamic into the leadership of your organisation, Nexus has developed a training program to guide your leaders toward leadership styles that put life at the center and develop robustness and resilience in this VUCA era.
Regenerative Business Model
The central focus of a regenerative company is its purpose – the impact it aims to generate in the world. Its business model is how it chooses to organise its activities, its production processes, and its value chain in order to fulfill this purpose while developing its economic, financial, and human vitality.
ReGen by Nexus enables you to mobilise your teams to rethink the business model of one of your products, an entire branch of your business, or even your whole organisation, thanks to a unique approach that combines design thinking, an augmented business canvas, and a wide range of collective intelligence methodologies.
Bespoke Consultancy for Regeneration
Do you want to initiate a regenerative dynamic within your company, adapted to the specific nature of its culture and challenges ?
ReGen by Nexus also offers bespoke consultancy to help you clarify your needs and intentions, and to collaboratively develop a unique regeneration project focused on the specific challenges you have identified.
This may include, for example, learning journeys to discover other regenerative innovations, design thinking workshops, engaging seminars, and regeneration training, combined, if necessary, with the other ReGen by Nexus products described above.
Notre Jeu ReSet
ReSet est un jeu collaboratif, à la fois dynamique, ludique et profond, qui permet aux organisations de se penser et de fonctionner comme des systèmes vivants, afin de se régénérer et de devenir régénératives. Par le jeu, les équipes font émerger des leviers concrets à impact positif, en interne comme en externe.
These organisations that tested ReSet
Matthieu Daum accompanied us from 2010 to 2017, a pivotal period as the three European provinces merged into a single province in 2011. Thanks to his expertise and professionalism, those years became an exciting adventure in co-creation where, whilst respecting everyone’s different roles, each of us was able to play a full part in the unification process. I remain deeply grateful for Matthieu’s support, for his great respect for people and his ability to move forward with us, step by step.
Véronique Fabre, Cenacle Sister, former Provincial for the Europe-Togo Province
« In a context of ageing and diminishment, Nexus has partnered with Society of Mary in Europe to strengthen leadership, reimagine structures, and revitalise its mission, nationally and internationally, ranging from leadership accompaniment, professional training and supervision, Provincial Chapters, ministry evaluation, and a major two-year organisational transformation.
The teams approach combines strategic clarity with deep respect for identity and mission born of their understanding of and respect for the culture of religious life, all delivered with warmth.
Working with Nexus, we were able to rethink how we lead and organise ourselves, through a creative, consultative process that enabled us to design new leadership and governance structures across eight countries, generating strong ownership of the outcome and a sense of unity. What could feel overwhelming became manageable thanks to their professional rigour and human touch. »
Martin McAnaney, former Provincial for the Europe Province, Society of Mary
« We entered into contact with Matthieu through the recommendation of another Congregation because we were searching for a facilitator for our general chapter, looking for different manners of approach our needs, discern together in the multicultural reality of our Congregation, and also in a process of organisational transformation. We found it interesting and provocative, to have a lay person as facilitator in our general chapter for the first time in our history. This was a great exercise in the preparatory process and during the chapter.
We were a group of leaders, leaving and working from different perspectives, and we practiced how to build good relationships and work together from our differences.
I recommend Nexus, because they help to mobilise our mental models and their methodsd (such as the “U” process) help us to transform our manner of thinking, feeling, work, and organize our actions to impact. »
Yaneth Moreno Rodriguez, SDS, Superior General, Salvatorian Sisters
« Nexus accompanied and advised us during a crucial phase in the development of our congregation, when we were facing major changes.
With their support, we undertook and successfully completed a profound process of transformation involving all 5,000 sisters across 71 countries on every continent.
What I appreciated: the quality of their expertise, their attentiveness, their respect, their understanding of our realities, and the firmness and flexibility with which they walked alongside us.
With the vision and tools we have equipped ourselves with, we can continue to chart our course towards the future with clear guidelines that bring our energies together. »
Françoise Massy, FMM, former Superior General of the Franciscan Missionaries of Mary
« As part of the French Bishops’ Conference’s ongoing reflection on the development of our governing bodies, Nexus’s support helped us to take a step back and organise a process involving numerous stakeholders. I particularly appreciated your ability to listen and your understanding of how ecclesiastical institutions operate, as well as the way you facilitated a genuine period of discernment. Your involvement helped to advance a complex process and to clarify several avenues for the future. »
Bishop Hugues de Woillemont, former Secretary General of the French Bishops’ Conference and current Director General of L’Œuvre d’Orient
« For several years, our Franciscan Province was unable to make important decisions. We made decisions based on urgent matters and, it must be said, on the influence of certain brothers. In 2022, on the advice of other Franciscan congregations, we turned to Nexus. This work involved virtually all the members of our fraternities. It required a significant level of commitment. Above all, it has been a process of learning to listen to one another, of speaking the truth, and of taking a clear and shared view of our situation. Little by little, barriers came down and we rediscovered ourselves as part of the same body, the same Province. The last chapter has enabled us to gain a clearer understanding of our limitations, but also of our strengths and our shared desire to live in the world in a Franciscan way. And ultimately, to take decisions that are widely supported. Through this process, synodality is no longer just an idea, but is gradually beginning to take root in our practices. »
Frédéric-Marie Le Méhauté, OFM, Provincial of France-Belgium
“The preparation for the General Chapter was a time of grace for us. We were accompanied by Matthieu Daum, from Nexus, both in the preparation and in the facilitation of the General Chapter. All the sisters of the Congregation were invited to participate in this journey in a creative and prayerful manner, and to look upon the reality of the Congregation with gratitude so that we might respond courageously to the call of Wisdom in the current context and reality. The fact that we didn’t have a predefined theme during the preparation meant we weren’t confined to a single theme, but were instead able to discern at every moment where God was leading us. I am grateful to Nexus for helping us to break out of our routines and embark on a new path of renewal, as we sought and explored together how to fulfil God’s plan.”
Rani Kurian, fdls, Superior General for the Daughters of Wisdom
« Nous voudrions vraiment vous remercier pour cette belle formation au leadership [Mon Leadership Incarné]. Merci pour le temps et l’énergie que vous avez consacrés, votre bienveillance, votre enthousiasme et votre pédagogie ; les exemples concrets ont rendu cette formation très enrichissante.
Nous vous en sommes sincèrement reconnaissantes ; sachez que vous êtes toujours la bienvenue chez nous.
Avec sincère gratitude »
Régina, Provincial of France, and her Council, Our Lady of the Missions
« As a leadership team of a religious missionary congregation, we realized that we could not continue as before and needed a new way forward. Through the Nexus consultation, we learned to communicate differently—using generative speaking and listening—and together designed a transformative process inspired by the U process. This journey led us to a decisive shift from repetition to regeneration. Their guidance helped us take courageous steps and begin functioning in a renewed, life giving way as a congregation. We warmly recommend their work to any community seeking genuine renewal! »
Lieve Stragier, Superior General, ICM, The Missionary Sisters of the Immaculate Heart of Mary
Et si les organisations, au lieu de détruire leur environnement, pouvaient contribuer à le régénérer ?
Nature-inspired Organisations
Matthieu Daum’s book
With over 20 years of experience supporting organisations and 10 years of expertise in regeneration, Matthieu Daum shares in his new book a structured reflection on Nature as a source of inspiration for efficient, high-performing and resilient organisations.
In an essay inspired by the twelve principles of Permaculture developed by David Holmgren, Matthieu provides numerous avenues to help you regenerate your organisation through concrete, practical actions, inspired by Nature, this 3.8 billion year old R&D laboratory.
