Social Compounding

Wealth is always built together

For centuries, people have turned trust and small contributions into things they could share: an archive, an insurance fund, land owned in common. We've collected twelve of these practices in one place, so you can borrow from what has worked for generations.

Homes that Stay Homes

Practice

Rising rents and homes bought as investments can push families out of their homes.

When housing is treated as a way to make money, people get priced out of where they live.

Communities push back by owning land together, limiting resale prices, and standing together to stop evictions, so residents can stay.

Caño Martín Peña

Puerto Rico

Residents avoided eviction by writing their own land trust law.

Context: From the 1930s, poor families built homes along a polluted channel in central San Juan. When plans to clean and dredge it took shape, residents feared rising land values would push them out.

In Practice: Between 2002 and 2004, residents and officials held over 700 meetings, and residents chose a land trust. Under a 2004 law they pushed for, the trust owns the land so it can’t be sold to developers, while families own their homes.

Since Then: The trust holds about 200 acres, home to some 26,000 people. After years of delay, work began in 2026 to dredge the channel and replant about 35 acres of mangroves along its banks.

Building Shared Infrastructure

Building Shared Infrastructure

Practice

Some needs are too big, and too long-term, for occasional help.

No one person can supply power, water, internet or a forest. These only become shared when a community organises around them for years.

It’s a long commitment, and much of the work is unglamorous: someone has to keep it all running.

Coopérnico

Portugal

Citizens pool their savings to put solar panels on the roofs of local organisations.

Context: Despite its strong sunshine, Portugal had no renewable energy cooperative. In 2013, sixteen citizens set one up so ordinary people could invest their savings in clean energy.

In Practice: Members lend money to put solar panels on rented roofs of charities, wineries and small businesses. The electricity is sold to the grid, members are repaid, and when the contract ends the panels are given to the roof’s owner.

Since Then: Around 7,000 members have funded 44 solar installations. Since 2020 the cooperative has also sold renewable electricity on a non-profit basis, with over 6,000 customer contracts by 2025.

Use It, Don’t Own It

Use It, Don’t Own It

Practice

One tool can serve a whole street.

Most tools, spaces, vehicles and machines sit idle far more than they’re used, yet everyone is expected to own their own.

Shared between several households, one drill or one car does far more work. It costs each person less, and more people get to use it.

Tool Library

Canada

Why buy a tool you’ll use once when you can borrow it instead?

Context: In 2012, a group of Toronto residents asked why every household buys tools that mostly sit unused. In 2013 they opened a lending library in the basement of a community centre, stocked with tools donated by neighbours.

In Practice: Members pay about €60 a year, reserve tools online and borrow them for up to a week. Some tools, mostly battery-powered ones, carry a small upkeep fee.

Since Then: By 2018 it had lent over 65,000 items. That year, high rent nearly forced it to close until supporters raised the necessary funds through crowdfunding. It now runs from one site in Toronto, with a shared workshop.

Keeping Shared Wealth Shared

Keeping Shared Wealth Shared

Practice

Something built together won’t stay shared on its own.

When a shared project succeeds, what it has built (land, trust, reputation, work) can start to look like something to cash in on.

Without legal or cultural protections, it can be sold off or taken over by a few people. The best time to lock in its purpose is early, before success makes it a target.

Aflaj Irrigation Systems

Oman

Instead of metering water, these desert villages share it out by time.

Context: In one of the world’s driest places, Omani villages dug channels to bring water from underground sources and springs. Some run through hand-dug tunnels for kilometres, with shafts down from the surface, so gravity alone carries water to the fields.

In Practice: Households own shares in the water, counted in time rather than volume, usually in half-hour turns. A manager chosen by the owners runs the system. Some water is auctioned off to pay for repairs.

Since Then: Water shares can be inherited, rented or sold separately from the land. Around 3,000 channels still work, some possibly 1,500 years old. Most turns are now timed by watch, but a few villages still use sundials and the stars.

Deciding Together

Deciding Together

Practice

Budgets, grants, and prices are never neutral.

Decisions about who gets served and who waits don’t have to rest with donors or distant officials.

The people affected can make them instead, through open meetings, reviews by their peers and budgets anyone can check. When the reasoning is visible, it can be questioned rather than simply handed down.

FRIDA

Transnational

The people applying for the grants are the ones who decide who gets them.

Context: Young feminist groups are often too small for big funders to notice. Around 2010, young activists set up a fund to pass donors’ money on to such groups in the Global South, led by girls, young women or trans youth under 30.

In Practice: Young activists first check that applicants qualify. The applicants then read summaries of each other’s proposals from their region and vote, anonymously, for their favourites. Nobody can vote for their own group.

Since Then: In 2024 it supported over 200 groups in more than 100 countries, giving over €2.7 million in grants. Its model, the first of its kind on a global scale, has inspired other funders.

Keeping Knowledge Alive

Keeping Knowledge Alive

Practice

A community that forgets what it knows can’t defend itself.

Skills, records, data, seeds and spoken histories are more than heritage. They help people run things today: knowing where land boundaries lie, which crops grow where, or who has a right to what.

Passing it down from one generation to the next protects it from being forgotten or taken by outsiders.

Trans Memory Archive

Argentina

Erased history, brought back by the community that lived it.

Context: In 2012, a trans activist started an archive to honour a friend who had collected photos of their community. Until then, trans lives in Argentina appeared mostly in police and morgue files.

In Practice: Trans women share old photos, letters and stories through a private Facebook group. A small team scans them in high quality, and the women tell their histories, including persecution under the dictatorship, in their own words.

Since Then: With over 25,000 items, it has been shown at museums and exhibitions including Madrid’s Reina Sofía and the São Paulo Biennial.

Shared Risk

Sharing Risk

Practice

When something goes wrong, one person should not have to carry it alone.

Some troubles are too big to face by yourself: illness, death, a lost job, a failed harvest, a home wrecked by disaster.

The idea here is to get ready for those moments together, before they arrive. People pool money, food, transport, tools, or local know-how, so that when a shock lands on one household, the whole group helps absorb it.

Burial Societies

South Africa

Families prepare together for the cost and burden of a funeral.

Context: From the late 1800s, colonial rule pushed Black men into migrant labour on the mines. To avoid being buried far from family, workers formed societies to bring their dead home and share the costs.

In Practice: Members set the rules and pay a small monthly amount into a shared fund. When a death hits a member’s family, the group helps with money or goods. Most groups use no insurance company, so members carry the risk together.

Since Then: Burial societies remain South Africa’s most common savings group, with millions of members. Their strength is trust: members know each other, run the fund together and turn up for the grieving family.

Keep Money Moving

Keep Money Moving

Practice

When money leaves a community, neighbours stop trading with each other.

Most communities have plenty to offer one another. What’s often missing is an easy way to trade, especially when cash is short.

Local currencies and exchange systems keep money and work moving between neighbours, without depending on cash from outside. They only work if enough people trust them and can actually spend what they earn.

Sarafu

Kenya

A community can create its own money when the national currency runs low.

Context: In 2010, a small non-profit launched a paper voucher in Mombasa’s informal settlements, where people had goods and skills to trade but little cash. After several versions, it became Sarafu.

In Practice: Members receive Sarafu on basic phones (with no internet needed) in exchange for their services, and spend it with local traders. A small shilling reserve limits how much can be cashed out, so most of it keeps circulating locally.

Since Then: When Covid lockdowns cut off cash income in 2020, around 55,000 Kenyans traded roughly €2.3 million worth of Sarafu in 18 months, mostly within their own neighbourhoods. Women and local savings groups were at the heart of it.

Owning the Work

Owning the Work

Practice

Work creates wealth, but that wealth often ends up far from the people who create it.

Most workers earn a wage, while the profits, the decisions and the long-term control go elsewhere.

But work can be organised so that ownership and any surplus stay with the people doing it. That means more than better pay: it gives them a say in what their work produces and where the rewards go.

CECOSESOLA

Venezuela

A large network of markets, clinics and services run without bosses.

Context: In 1967, a cooperative member in Barquisimeto died and his family couldn’t afford the funeral. Ten local cooperatives responded by setting up a shared funeral service, and later added food markets, credit and health care.

In Practice: Workers rotate between jobs and mostly earn the same. Dozens of cooperatives and community groups make decisions together in open meetings, aiming for agreement rather than a vote, with no managers.

Since Then: Its weekly food markets serve around 40% of the city. The network paid for and built its own hospital, where surgery costs half the private price, and its clinics care for up to 250,000 people a year.

A Little from Everyone

A Little from Everyone

Practice

Small amounts add up to something bigger than money.

Regular payments, pooled together, can become a lump sum, a safety net or money to invest.

Just as valuable is what grows alongside them: the habit of paying in, and trust that everyone else will keep doing the same.

Ekub

Ethiopia

Members pay into a shared fund and take turns receiving the whole amount.

Context: Ethiopian banks usually ask for land or property as security when giving a loan, which small traders rarely have. Ekub fills the gap by letting people save and borrow together.

In Practice: Members agree verbally, without a contract, and pay a fixed amount each round. A draw usually decides who takes the pot, until everyone has had one turn and got back what they paid in. Early winners often need someone who promises to cover their payments if they stop.

Since Then: A national survey found 51% of Ethiopia’s informal business owners started their business with their own savings and Ekub. Apps now run digital Ekubs too, charging users a small fee for the service.

Cutting Everyday Costs

Cutting Everyday Costs

Practice

Life costs less when people do things together.

Food, repairs, clothes, childcare: most households pay for these alone, every month. Sharing cuts the cost.

Families buying food together get a bulk price, and a neighbour who fixes things saves everyone a repair bill. Skills get passed on, and neighbours get to know each other.

Repair Cafés

Netherlands

A free workshop where you can fix your broken things.

Context: A Dutch journalist writing about waste-related issues saw repair as a solution. In October 2009 she held the first Repair Café in a theatre in Amsterdam. It was packed, with visitors coming from outside the city.

In Practice: Anyone can bring a broken item, from clothes to bikes, and fix it for free alongside a skilled volunteer, using the tools provided. Any local group can start its own Repair Café with help from a Dutch foundation.

Since Then: Over 3,800 Repair Cafés now run worldwide. In 2024, the 215 cafés that kept records logged over 37,000 repairs, most often vacuum cleaners, coffee makers and trousers. 62% were fixed.

Breaking the Debt Trap

Breaking the Debt Trap

Practice

Debt can give a lender control over your future.

People caught in debt traps or borrowing from predatory lenders can end up giving away their wages, their home or their education just to keep up with what they owe.

Groups can push back together. They share legal knowledge, negotiate as one, or lend money with no interest, so no one carries the debt, or the shame, alone.

El Barzón

Mexico

Debtors organise to put pressure on banks together.

Context: In 1993, indebted farmers in Jalisco started protesting against the banks. When the peso lost half its value in late 1994, interest rates soared and many loans became unpayable. Small business owners and families joined, and the movement spread nationwide.

In Practice: Local groups across the country offer members legal advice, help them negotiate with banks and organise protests. Many members paid what they considered fair into court-supervised accounts instead of paying the bank.

Since Then: By the mid-1990s it claimed half a million members or more. Its pressure helped push the government into debt relief programmes. Local groups remain active, joining farmers’ protests in Zacatecas in 2025.

The practices that we share here aren’t automatically “good”.

Community-led systems can build up trust, care, and capacity. But they can just as easily build up shame, obligation, gatekeeping, surveillance, unpaid work, and dependency. These principles are meant to travel with the social compounding mechanisms we identified. Keep them in mind as you read or come up with new ideas.

Access is not the same as power

Being able to use a shared system isn’t the same as having a say in how it’s run. Who gets to change the rules, control the data, manage its money and property, and shape where it goes?

Taking part isn’t the same as having a voice

Meetings, votes, and assemblies can still be dominated by whoever has more time, confidence, status, education, fluency in the language, or better access to the technology.

Conflict is not failure

Disagreements are bound to happen, and they don’t mean the system is broken. Any shared system needs fair ways to settle disputes, hold people to account and put things right.

Local Isn’t Always Better

Local systems can build accountability and belonging, but they can also shut people out, breed distrust of outsiders and reinforce old hierarchies.

Informal can be a strength and a risk

Informal systems tend to be fast, flexible, and caring. They can also lack transparency, legal protection, and safeguards when something goes wrong.

Resilience can become a trap

Praising people for coping can excuse the conditions forcing them to cope in the first place. They shouldn’t have to endure such conditions at all.

Boundaries can shut people out

Every shared system needs rules about who can use it, benefit from it, contribute, and decide. Those rules have to be clear, open to change, and fair to newcomers and outsiders.

Leaving has to be possible

Trust and belonging keep care alive, but they can also make it hard to say no. Healthy systems leave room to disagree, step back, or walk away entirely.

The future shouldn’t silence the present

Thinking ahead for future generations matters, but it shouldn’t be used to ignore what people urgently need right now.

Nature isn’t a side issue

Land, water, seeds and forests aren’t a backdrop to shared wealth or a separate cause. Every shared system depends on them, and how a community treats nature is part of how it treats itself.

Memory is political

Archives, maps, spoken histories, data and inherited knowledge decide whose suffering counts, whose expertise is recognised and whose claims are taken seriously.

What You Measure Can Distort What You Value

Data often rewards what is easy to count and misses what matters most: trust, dignity, confidence, safety, shared knowledge and collective imagination.

About

“The Missing Us: Why Independence Feels Safer Than Belonging”an article produced by us, the Open Future Lab, and it builds on interviews with 26 people across 13 countries about how they picture their lives and futures. One person in Croatia told us, "It's much easier to borrow money from banks. Borrowing money from people, it's actually a very humiliating thing." Many others felt the same pressure to look self-sufficient, even while depending on systems and people in ways that of ten stay invisible. When they imagined the future, they jumped between their private lives and planetary crises. The everyday us in between was the hardest to picture. Without it, independence becomes the safest story to tell about oneself.

In our project Social Compounding, we explore the future of wealth and resilience as something fundamentally collective.

In finance, compounding needs need money for money to grow, which excludes out anyone beginning with nothing or even in deficit. Social compounding works the other way round. It runs on the one thing you've got whether you're rich or not: other people. The returns come from participation. A shared fund gets stronger the more people put into it and use it. So does a co-op, or a piece of land a community owns together, or an archive. It grows. And the group ends up with something none of them could have bought on their own: a safety net, a resource, a vote over things that affect them.

We built a tool, a library of practices to make that resilience logic visible and usable, gathering twelve patterns of social wealth in one place, backed by real-life case studies from around the world. We hope the library gives people a way to imagine how collective action might become part of their own context – as something already happening, in patterns they can learn from and build on.
