In 2017, we met the entrepreneur. In 2026, we stood inside the institution he had built. As Harambeans approaches its 20th anniversary, Dangote’s journey offers us a challenge of our own: what should a network of exceptional people become over the next twenty years?
On September 10, I stood with a group of Harambeans inside the Dangote Refinery in Lagos. It was one of those moments when the physical scale of an idea becomes impossible to ignore. Nearly a decade earlier, in 2017, we had presented Aliko Dangote with our Malaika Award for Champion of African Entrepreneurship. He had already built one of Africa’s great business empires; we were recognising what he had accomplished, not predicting what he might become. Standing inside the refinery this week, I found myself thinking about the distance between those two moments. In 2017, we met the entrepreneur. In 2026, we stood inside the institution he had built.
That distinction matters as Harambeans approaches its own twentieth anniversary. When we began, our mission was straightforward: find exceptional African entrepreneurs and bring them into a community where they could build relationships across borders. We believed Africa did not lack talent. What was missing was trust between people who could build together. We were right about the talent. What we underestimated was what could happen when trust compounds over time.
But standing inside the refinery suggested another question, one that goes beyond the evolution of a company or even an entrepreneurial network: what happens when one person’s extraordinary achievement changes what an entire generation believes is possible?
From Potential to Productive Capacity
In our fireside chat, Dangote himself offered a useful warning about the danger of stopping at potential. “Everybody talks about Africa potential,” he told us. “But unless you put that potential into reality, nothing will happen.”
That is what makes the refinery more than an extraordinary business achievement. Nigeria has enormous oil reserves but historically imported much of the fuel it consumed. Dangote decided that African resources should be matched by African productive capacity, and that industrialization could not simply be left to someone else. The result is a refinery capable of processing 650,000 barrels of crude a day, surrounded by petrochemicals, storage, power, marine infrastructure and logistics. It is a remarkable piece of industrial infrastructure, but its significance may ultimately extend far beyond what it produces.
Dangote is now preparing to take the refinery public in what he calls a “people’s IPO,” marking another stage in the evolution of an asset created through concentrated entrepreneurial risk into a broader institutional phase. Dangote described his ambition plainly: “Our legacy is to industrialize Africa.” But what stayed with me even more was what he said next: “Some other people will even do bigger things going forward.” That sentence contains a profound idea. It is the difference between building something extraordinary and changing what other people believe they can build. A company creates value through what it produces; an institution changes the conditions under which other people can create value.
The Dome That Changed What Was Possible
Five centuries earlier, another builder confronted a seemingly impossible challenge. For more than a century, Florence’s great cathedral stood beneath a giant hole. Its architects had envisioned a dome larger than anything the world had ever seen, but no one knew how to build it. Then came Filippo Brunelleschi. Between 1420 and 1436, he constructed the dome that had eluded generations of builders. It remains the largest masonry dome in the world, and he built it without the enormous wooden framework that conventional construction would have required.
Brunelleschi’s achievement mattered for more than its engineering. The dome became one of the great symbols of the Renaissance, a visible demonstration that human ingenuity could overcome limits that had once appeared absolute. Brunelleschi did not single-handedly create the Renaissance, but his achievement helped expand the sense of what was possible. Florence soon produced a remarkable generation of artists and thinkers – Donatello, Leonardo, Michelangelo, Botticelli, Raphael and others – who pushed the boundaries of their age. Leonardo studied Brunelleschi’s machines; Michelangelo later drew directly on his architectural innovations in designing St. Peter’s.
The important point is not that Brunelleschi caused all that followed, but that great achievements can change the ambition of the people who witness them. Once the impossible has been done, the question changes from “Can this be done?” to “What else might be possible?” That is what I found myself thinking about inside Dangote’s refinery. Perhaps its most important output will not ultimately be measured in barrels, but in ambition. When an African entrepreneur sees what Dangote has built, the question is no longer simply whether an African can build something this big. It becomes: why shouldn’t I?
That is how renaissances begin. One person builds what others thought impossible; others see it, their sense of possibility expands, and they begin to build bigger themselves. If Brunelleschi’s dome helped give Florence permission to dream beyond the limits of its age, perhaps Dangote’s refinery can give Africa the same permission.
An African Renaissance of ambition would mean something very specific: a generation of entrepreneurs who no longer ask whether something has ever been built in Africa before deciding whether to attempt it. It would mean founders who think in decades rather than quarters, in continents rather than countries, and in institutions rather than companies. It would mean African capital backing African ambition, and each generation of builders making the ambitions of the next seem less audacious.
Perhaps that is the refinery’s greatest potential legacy, not simply what it produces, but what it makes Africans believe they can build.
What Twenty Years of Trust Have Built
And that brings me back to Harambeans. For twenty years, Harambeans has been built on a simple insight: exceptional entrepreneurs need more than capital. They need trusted relationships that help them access the resources required to build enduring businesses.
Over time, we have learned that the real value of a network is not simply the introductions it creates. It is what becomes possible when capital, customers, talent and expertise can move through the same trusted relationships.
When trust compounds, relationships begin to function like infrastructure.
Consider Velani Mboweni H’18, founder of Lula, a South African logistics and mobility company.
Lula illustrates what happens when a network begins to operate as an ecosystem. Through relationships across the Harambeans Alliance, Lula has accessed multiple forms of support: investment connections through Launch Africa Ventures and the Prosperity Fund, a customer relationship with Yoco, developer talent through WeThinkCode, and commercial opportunities associated with the Oppenheimer Fellowship.
These are different resources addressing different business needs. Capital helps finance growth. Customers generate revenue. Talent strengthens execution. Enterprise relationships open commercial markets.
The significance is not any single connection. It is that these resources can be accessed through an interconnected community, rather than through entirely separate networks that an entrepreneur must build from scratch.
And the relationship is reciprocal. In 2021, Mboweni personally funded travel for other Harambeans members. The entrepreneur who benefited from the ecosystem was also contributing to it.
This is the difference between a network that connects people and an ecosystem that helps businesses grow.
The first twenty years of Harambeans were largely about building the network effect: bringing exceptional people together and allowing relationships to compound. The next twenty must be about creating an institutional effect: making the capital, knowledge, talent and commercial opportunities accumulated by one generation systematically available to the next.
From Network to Entrepreneurial Infrastructure
That transition requires a different set of questions.
Can the capital accumulated by one generation help finance the next? Can a company’s customer relationships create commercial pathways for other entrepreneurs? Can expertise and talent circulate across the portfolio? Can philanthropic partnerships become structured pathways through which promising businesses demonstrate their capabilities and earn access to larger markets?
Our work with the Africa Jobs Fund and the Harambean Oppenheimer Fellowship points toward this next stage. The ambition is to move beyond helping entrepreneurs meet the right people and toward building repeatable mechanisms that help them secure capital, develop their businesses and access commercial opportunities.
For a supporter of Harambeans, this creates an opportunity to help build something more durable than a series of individual success stories: an institution that makes the resources required to build successful businesses increasingly accessible to the next generation.
The ambition is to turn twenty years of accumulated trust into enduring infrastructure for African entrepreneurship.
The Challenge of De Risking What Comes Next
There is a striking parallel with Dangote’s own philosophy. He described his role to us as “de-risking Africa.” Somebody has to take the first risk that others consider irrational: build the factory, prove the market, establish the infrastructure. Once the opportunity becomes demonstrably real, other capital can follow.
The same principle applies to entrepreneurship. An investor can wait for certainty, or help create it. A philanthropist can fund another programme, or underwrite an experiment that makes a new market investable. An experienced founder can simply celebrate his own success, or use what he has learned to shorten the path for someone coming behind him.
This is why the next phase of Harambeans cannot be built by founders alone. It requires investors willing to back the ecosystem as well as individual companies, experts willing to share knowledge, philanthropists willing to absorb risks that commercial capital cannot yet take, partners able to open markets, and alumni willing to put their accumulated experience and relationships to work for those coming behind them. Dangote put another part of the principle simply during our conversation: “We have to believe in ourselves, and we have to also try and be together.”
What Will We Build Together?
The question is no longer whether Harambeans can build a powerful network. We have done that. The question is whether we can turn that network into infrastructure that compounds opportunity. What happens if the capital of the Harambean community follows its talent, its knowledge travels across generations, founders become investors, investors become institution builders, philanthropists help prove opportunities that commercial markets are not yet ready to finance, and partners help turn those opportunities into durable businesses? What happens if the success of one Harambean systematically makes the path easier for the next?
There is a temptation, when looking at Dangote, to ask how Africa can produce another Dangote. I think that is the wrong question. The more consequential question is whether we can create the conditions in which hundreds of ambitious Africans can attempt things that today seem improbable and in which the success of one makes it easier for the next.
Dangote is building productive infrastructure that can enable others to industrialize. Our opportunity is to build entrepreneurial infrastructure that can enable others to build. The greatest achievement of a pioneer is not necessarily the thing he builds; it is the new standard of possibility he leaves behind.
Brunelleschi closed a hole in the roof of a cathedral and helped expand the imagination of a civilization. Dangote built a refinery and may have opened the imagination of a continent. Now the question is what we will do with that opening.
That is the Dangote Challenge: not simply to produce another Dangote, but to create an African Renaissance of ambition in which every generation dares to build what the previous generation could not imagine.
It is a challenge to every investor, expert, philanthropist, partner and alumnus gathered under the Alliance and to generations of Harambeans who have not yet joined us.
Twenty years ago, we set out to find the people who could build Africa’s future. We found them. Now we have to build what they can build together.
