Arnergy has named Ernest Eguasa as interim chief executive, ten months after he joined the Nigerian solar company as chief financial officer, succeeding founder Femi Adeyemo after 13 years in the role. The handover took effect on 1 November 2026, with Adeyemo, who founded the business in 2013, remaining a shareholder. The transition was orderly, pre-planned and notably low on drama — a template that is becoming familiar across Africa’s venture-backed technology sector.
Adeyemo’s exit is the latest in a wave of founder-CEO departures that has swept the continent over the past 18 months. The list is long and growing: Adegoke Olubusi at Helium Health, Tayo Oviosu at Paga, Sim Shagaya at uLesson, Andrew Garza at Lifestores Healthcare, Gregory Rockson at mPharma, Yele Bademosi at Onboard, Adewale Yusuf at AltSchool Africa, Katlego Maphai at Yoco, Clayton Hayward at EFT Corporation, Amir Allam at Elmenus, Daniel Yu at Wasoko and Omar Gabr at Instabug. At least seventeen such transitions have been tracked, spanning health-tech, fintech, edtech, payments infrastructure, e-commerce and solar energy.
The question that hangs over this procession is whether it is a distinctly Nigerian phenomenon. The evidence is mixed, and the answer depends on whether one measures volume, capital or structural maturity.
The Nigerian cluster is real — and large
Of the seventeen tracked exits, seven are Nigerian-headquartered: Helium Health, Paga, uLesson, Lifestores, Arnergy, Onboard and AltSchool Africa. That is 41 per cent of the total — a clear plurality, but not a majority. South Africa accounts for four (24 per cent), Kenya three (18 per cent), Egypt two (12 per cent) and Ghana one (6 per cent). Nigeria is the largest single cluster, but South Africa and Kenya together match it. The wave is continental; Nigeria is its densest concentration.
That density is not accidental. Nigeria has long been the continent’s volume engine for venture activity. In 2016 — the year that many of the departing founders raised their defining early rounds — Nigerian startups captured $109 million, or 29.8 per cent of all African venture funding, narrowly ahead of South Africa and Kenya. Between 2019 and 2023, Nigerian startups received $4.4 billion, close to 30 per cent of the continent’s $15 billion total. At its peak, Nigeria attracted up to 35 per cent of Africa’s startup funding.
That capital built a large cohort of companies that are now reaching maturity simultaneously. Nigeria also has the highest number of startups on the continent — over 20,000 by some counts, far ahead of Egypt’s 8,000 — and the highest deal volume. More companies raising early rounds in 2014–2016 means more founders hitting the eight-to-fourteen-year tenure band at which exits cluster. The Nigerian accent in the exit wave is, in part, a simple function of cohort size.
The funding landscape has shifted beneath the exits
But the exits are happening against a backdrop of dramatic change in Nigeria’s funding position. In 2025, African startups raised $3.1 billion, up from $2.2 billion in 2024. Nigeria, however, raised only $343 million — a 17 per cent year-on-year decline — and its share of continental venture capital fell to 11 per cent, its lowest level since 2019. Kenya overtook Nigeria as the continent’s top destination, raising $933.6 million, followed by South Africa at $625.7 million and Egypt at $430 million.
The causes are macroeconomic as much as structural. The naira’s depreciation, from around N400 to over N1,600 at its peak, wiped out dollar-denominated returns for early investors and dampened appetite for pre-seed and early-stage bets. High inflation weakened consumer purchasing power, hitting fintech and e-commerce startups whose margins depend on disposable income. Nigeria was the only member of Africa’s “big four” to post a funding decline in 2025, even as the group collectively captured 82 per cent of all startup funding on the continent.
This creates a paradox. Nigeria has the largest cohort of maturing, venture-backed companies, but the capital environment that once sustained them has tightened. For early investors seeking de-risked returns, the pressure to professionalise management and prepare for exit is acute. For founders, the limits of their appetite for running large organisations in a volatile currency environment become harder to ignore.
The succession playbook is diversifying
The replacements themselves reveal how boards are navigating this inflection point. Internal promotion is the dominant model. At Paga, Opeyemi Oyinloye, a seven-year veteran of business operations, stepped in as acting CEO of the Nigeria business while founder Tayo Oviosu moved to group CEO after 17 years. At uLesson, founder Sim Shagaya handed over to Iheanyi Akwitti after eight years, moving to executive chairman. At Lifestores, co-founder Gloria Udekwe took over from Andrew Garza, who moved to a board and advisory role after eight years. At mPharma, COO Kwesi Arhin succeeded founder Gregory Rockson, who became chairman after 11 years. At Onboard, product lead Paul Oladimeji succeeded Yele Bademosi, who became chairman. At AltSchool Africa, co-founder Akintunde Sultan took over from Adewale Yusuf.
External hiring is the exception. South Africa’s Yoco appointed Carsten Höltkemeyer, a German executive with no prior Africa experience, after a global search concluded that “the right scaling experience was not available locally.” OfferZen and Twiga Foods also brought in external operators, with boards citing the need for “operational grip” at scale. EFT Corporation took the most radical route, abolishing the group CEO role entirely and distributing authority across four divisional managing directors — Corrie Bakker, Paul Carter-Brown, Paul Selibas and Mike Smits — each running their own P&L. Arnergy’s interim CFO appointment is a variant on the stabilisation playbook: a finance-led handover ahead of a permanent appointment.
The founder does not usually leave
What unites almost all these transitions is that the founder does not go far. Oviosu remains group CEO. Shagaya is executive chairman. Garza is on the board. Rockson chairs mPharma. Bademosi chairs Onboard. Adeyemo remains a shareholder at Arnergy. Hayward remains an advisory shareholder at EFT. Yusuf will support AltSchool from a director and leadership level while based in the United States. The pattern is sideways movement, not exit.
That creates a governance structure with limited precedent. The incoming chief executive is tasked with professionalising operations, imposing “operational discipline” and preparing the company for its “next phase” — the uniform language of board announcements — while the founder retains influence over strategy, capital allocation or board decisions. None of the companies that have completed this handover have publicly addressed how that tension will be managed over a multi-year horizon.
The bottom line
The honest assessment is that the wave is continental, but its epicentre is increasingly Nigerian. Nigeria accounts for 41 per cent of the tracked exits because it has the largest cohort of venture-backed companies that raised institutional capital in the 2014–2016 window. The structural drivers — early investors seeking liquidity, founders confronting the limits of their appetite for running large organisations, and a scarcity of executives who combine regional knowledge with institutional scaling experience — are identical in Lagos, Cape Town, Nairobi and Cairo. What differs is the density.
That density is now being tested by a funding environment that has turned against Nigeria. The founders who raised in the boom years are handing over to operators who must navigate a currency crisis, a tightened capital market and the expectations of investors who want exit-ready management rather than founder-led experimentation. Whether those operators succeed will depend less on their nationality than on whether African boards can resolve the governance question that every one of these transitions has so far left unanswered: how much authority does a founder retain, and for how long, after the handover?
The current wave is therefore less a conclusion than an early stress test. Nigeria is where that test is most concentrated, and where the outcome will be watched most closely. But the experiment is continental, and it is only beginning.
