Globacom did not enter Nigeria’s telecommunications industry first. It entered after the market had already begun to take shape, with established operators, millions of naira in infrastructure and customers who already had reasons to stay with the networks they knew. Yet when Mike Adenuga launched Glo in 2003, the newcomer did something that many late entrants struggle to do: it gave the market a reason to change.
The company arrived with one-kobo-per-second billing when established operators were charging by the minute. It cut SIM card prices that had reached as high as ₦25,000 and eventually gave them away for free. Within its first year, Glo reportedly had one million subscribers across 87 Nigerian towns. The company was not the first to recognise Nigeria’s telecommunications opportunity, but it understood something important about entering a crowded market.
You do not always need to arrive first; you need to give people a reason to choose you.
That approach says a lot about the businessman behind the green network.
Mike Adenuga had been building businesses long before Glo. By the age of 26, he had reportedly made his first million through trading lace fabrics, soft drinks and general merchandise. Before telecommunications, he had already moved into banking and oil and gas, establishing Consolidated Oil in 1990, now Conoil Producing. A year later, the company struck oil in commercial quantities in the shallow waters of Ondo State, marking a significant achievement for indigenous participation in Nigeria’s oil industry.
His background helps explain why telecommunications was never simply a decision to start a phone company. Adenuga had already developed a habit of entering industries where the opportunity was large, the competition was serious and the barriers to entry were high.
Perhaps the most unlikely chapter of that journey came much earlier. While studying Business Administration at Northwestern Oklahoma State University and later completing an MBA at Pace University in New York, Adenuga worked as a taxi driver in the United States to support himself and pay his tuition. It was a very different world from the one he would eventually occupy, but the contrast is part of what makes his story compelling. The future billionaire was not handed a business empire. He was building his way towards one.
By the time he turned his attention to telecommunications, he had already accumulated the capital and experience to take a much bigger risk. The first attempt did not go smoothly. Adenuga secured a conditional GSM licence in 1999, but it was later revoked. When another licensing opportunity came in 2003, he returned, secured a new licence and launched Globacom on August 29.
The obvious question was: why enter a market where other companies already had a head start?
Adenuga’s answer was written into Glo’s strategy. Instead of trying to look like the companies already dominating the market, he challenged some of the things customers had come to accept as normal.
Per-second billing challenged the way calls were charged. Lower SIM prices challenged the cost of entering the mobile market. And as Glo grew, Adenuga made an even bigger move that went far beyond pricing.
In 2009, Globacom’s Glo-1 submarine cable landed in Lagos, connecting Nigeria directly to the United Kingdom through a fibre-optic link and providing additional international telecommunications capacity. For a company that had become known for cheaper calls and affordable SIM cards, investing in a major piece of international infrastructure revealed a much larger ambition. Adenuga was not only interested in selling access to a network; he was willing to invest in the infrastructure behind that access.
That is the pattern that runs through Adenuga’s business career: enter, differentiate and then build beyond what people expect.
It is also why Glo’s story cannot be reduced to telecommunications alone.
Adenuga’s business interests now stretch across oil and gas, banking, real estate and other sectors. Yet unlike many business empires that eventually become fragmented among different investors or publicly traded shareholders, Globacom has remained under Adenuga’s ownership more than two decades after its launch.
That is particularly notable when viewed against the history of Nigeria’s other major telecommunications companies. MTN Nigeria became publicly listed on the Nigerian Exchange in 2019. Airtel Africa is publicly traded in London and Lagos. Etisalat Nigeria, after defaulting on a $1.2 billion loan, went through an ownership crisis and eventually became 9mobile. Globacom took a different path, remaining privately held under Adenuga.
There is another unusual part of the story: the founder himself has remained remarkably difficult to see.
Adenuga rarely gives interviews and has generally stayed away from the constant public attention that surrounds many wealthy entrepreneurs. The Glo brand is everywhere, but its founder is not. Millions of Nigerians interact with businesses he built without ever hearing him explain those businesses in the way today’s founders often do.
That quietness makes the scale of what he has built even more striking.
From trading to oil, from oil to telecommunications, and from telecommunications into the infrastructure behind it, Adenuga has repeatedly entered industries where the competition was already established and found room to build something of his own. His story is not really about a taxi driver who became a billionaire. The taxi was simply one chapter. The bigger story is about a businessman who kept finding his way into industries where the stakes were high and then staying long enough to make his presence matter.
He was not the first to enter Nigeria’s telecom market.
He did not have the advantage of being the established player.
But he found a way to change the market after he arrived.
And even after more than two decades, he still owns the company he built.
Sometimes, building a business is not about being the first person through the door. It is about being the person who changes what happens after you walk through it.
