Why / Our future is at stake

Humanity
is at risk.

Humanity is taking more from the Earth than it can regenerate. Our own future is at stake.

Solutions exist. Knowledge, technology and capital are available. Yet knowing what to do does not mean we do it. Closing that gap between knowledge and action is the work.

That is why we work on behaviour: to support a sustainable future for humanity by influencing the economic system itself.

What / Change behaviour at scale

One billion people.

Decisions that
serve humanity.

Our ambition. One billion individuals have the power to shift the economic system.

Our ambition is to support one billion people to select the most sustainable alternative in their daily choices and lifestyle.

As those small decisions weight at scale, demand changes. Businesses then have good reasons to change what they produce, offer and invest in. This is how we intend to influence the economic system to serve humanity.

What we do

Hospitality connects us. Humanity is whom we serve. Sustainability guides the decisions we seek to influence.

How we scale

We scale
through culture.

Culture moves faster than governance. It reaches people through emotion, identity and belonging, without waiting for formal institutions to change.

Music, art, sport, entertainment and influential voices can carry our narrative across communities and borders. We bring it into events, festivals and hospitality, especially restaurants and hotels. These are places where people already gather, connect and share experiences. They offer ways to spread the message and explore how decisions in everyday life could be made within the limits of one planet.

Our collaboration with Love Tomorrow on the iconic grounds of Tomorrowland shows how we bring the purpose into a cultural setting. The goal goes beyond attention: to influence behaviour and more sustainable decisions that serve humanity.

Our innovation / Support everyday choices

BEE

by sociisgroup

Behavioural Engine with Ethics

From values
to everyday choices.

BEE is our innovation: an AI powered behavioural application, designed to surface contradictions between what people value deeply and how they behave, helping them explore more sustainable alternatives that fit their needs and serve humanity.

BEE is intended to be integrated into cultural collaborations, gatherings, festivals and hospitality, especially restaurants and hotels. A trusted companion in everyday decisions. Buddies to engage with other humans in similar situation. Communities to anchor new more sustainable habits.

Our gatherings / The 64 & The 300

Bringing people together
to create impact.

Alongside our innovation, BEE, we create gatherings and experiences that bring the purpose to life. For The 64 and The 300, we carefully curate people from business, culture, academia and society who can support our cause through their perspectives, influence, capabilities and values. We connect them to explore how they can help turn the purpose into action.

The 64

A smaller room.
A deeper exchange.

The 64 brings a carefully chosen group together around the table. Hospitality creates the time and trust to listen, challenge assumptions and explore what we could do together.

We connect people who can contribute through their decisions, organisations, ideas and networks. These relationships can lead to collaborations, cultural projects and opportunities to develop and test BEE.

The 300

A wider stage.
A shared direction.

The 300 brings a wider circle of invited people into the purpose through culture, hospitality and human connection. The founding gathering took place on the grounds of Tomorrowland, in collaboration with Love Tomorrow.

We bring different worlds together to open new perspectives and create relationships that can carry the work beyond the gathering.
