/ Presentation /



The history of Twiza comes from a conviction : faced with the current environmental and social challenges, the solutions brought by the ecological habitat make a path towards the future.

In transport, in the hotel industry, in trade, the digital technology has changed everything ! We believe that ecological housing can bring back together the human concerns with the economical and environmental matters.

If we want this idea to come true, we need a digital tool that will bring the actors closer to this ecological transition.

This tool is Twiza : the Ecological Habitat Network. 

=> Update (05/15/17) : € 60.000 raised in 9 days !



There is an important place regarding the protection of heritage buildings as well as eco housing :
– technical solutions such as wood construction, solar energy, ecological insulation, permaculture … But unfortunately they’re hardly known.

– numerous actors such as project leaders, associations, professionals … But they’re isolated people.


With 4 million of ill-housed people poorly built houses in France, the conventional building industry no longer achieves its objectives. In addition, it has a disastrous impact on the environment.

Inhabitants and professionals, many have more ambitious views on this industry. Alternative and relevant solutions do exist : wood construction, clean energy production, traditional masonry, reuse of materials, etc… Associated jobs/functions are still alive, always defended by activists and enthusiasts who share a vision: placing humans at the core



Thanks to the internet, we enable a better access on meeting the important people on the ecological transition in the building industry. We facilitate the meeting of the actors of the ecological transition in the building field. We are gradually building this ecosystem that gives access to the implementation of solutions that respect humans and the environment.


Our 1st Success : some participatory construction projects has changed the game. Organizing or finding a participatory construction project became very simple. Thousands of people have already met via Twiza on one of the 1,500 projects completed in 3 years. Thousands of enthusiastic testimonials have been shared between users. This experience has changed their lives. With 200% annual growth, we are delighted to see more and more people joining the network and getting involved.




The Next step

We will add many facets to this ecosystem, we want to promote :

  • Adapted professionals
  • Events
  • Shared places (third-places)
  • Trainings


The Goal

We want to raise € 60,000 at least. Thus, we will be able to pay for the development of the functionalities of this platform, according to the needs we’ve identified. Finally, we aim to achieve a financial balance. Then, we’ll be able to subside needed time to develop the functionalities, corresponding to the identified needs, and to achieve financial balance.


Return on investment

In exchange for your investment, you quarterly receive a percentage of the turnover of SAS LICHEN ( for 5 years. We aim for an annual return of 11.39%.

For instance: for € 1,000 invested you will receive quarterly 0.117% of our turnover, ie. an estimated 1715.18 € over 5 years.

You can do a simulation at the top of this page.

Our Company

Lichen (alias Twiza) is a simplified joint-stock company created in 2016 with variable capital of € 70,000. It is represented by Cédric DANIEL and Vincent PEIGNÉ, both of whom are corporate officers.


Positive impacts

Twiza creates social ties and promotes short circuits and local jobs.

Economic impact

By facilitating new and ancestral ecological techniques, the Twiza network promotes a virtuous economy:

  • The short circuits, with the use of local materials and local jobs,
  • Skilled employment, professionals with specific know-how : depending on the materials, the building, the local architecture…

It is therefore local employment, no risk of relocation and skilled jobs that are carried by this sector.

Social Impact

Some of our users confess of the the intensity of the human adventure they live through the Twiza network.

On one hand, it is the self-confidence that is consolidated by the experience of the participatory site and the opportunity to realize personally through a material realization, which concerns everyone.

On the other hand, it is the relationship with others that is upset. It is the opportunity to be useful, to give and to receive, and to participate in a collective work. According to the exchanges we have with the users, the relationships woven thanks to Twiza persist in the time.

Environmental impact

Carbon balance, grey energy, toxicity, sustainability, long-term profitability, resource consumption.

Compared to conventional techniques, ecological techniques are much more efficient.

For example, by comparing:

  • the life cycle, wood consumes 70 times less energy than PVC,
  • the carbon balance, the straw stores 2.7 times what the polystyrene emits,
  • the cost of gray energy, cellulose wadding has 8 times less impact than rock wool.


In the ecological habitat market, Twiza is positioning itself as a meeting facilitator

Each user contributes to the network.

60 000 € en 9 jours ; un record !
15 May 2017

Première étape validée en 9 jours !

Nous avons le plaisir de commencer cette semaine avec le franchissement d’une étape importante; le seuil de 60 000 € qui valide l’opération.

Objectif : entre 60 000 € et 120 000 €


Consolider le projet

Innover c’est aussi apprendre, et cela demande du temps. A partir de maintenant, chaque investissement supplémentaire va permettre de consolider l’avenir de Twiza. En effet, tout ce que nous obtiendrons au dessus de 60.000€ va être réparti de la façon suivante ; 50% en investissement et 50% en réserve financière. 

50% d’investissement (par ordre de priorité) : 

  1. Interventions ponctuelles d’experts en architecture web (SEM, SEO & SMO) pour viser l’excellence,
  2. Création de l’application mobile (Androïd et IPhone) pour accélérer le développement et l’activité,
  3. Conseil Juridique (montage juridique, création des contrats, etc…) pour faciliter le développement à l’international .

50% de réserve financière :

Cette réserve financière sera disponible en cas d’imprévu. Elle sera un facteur de sérénité, et donc d’efficacité pour l’équipe. 

Investir maintenant c’est contribuer à sécuriser encore plus l’investissement de tous.

Pour soutenir et investir =>

Parlez-en autour de vous car ensemble ces petits gestes ont vraiment de l’impact 🙂
