In Lagos, the checkout button has a name. For roughly one in five online transactions in Nigeria, that button routes through Paystack [Paystack]. Ten years after Shola Akinlade and Ezra Olubi started writing code for a payments API in a city most global processors had ignored, the company now says it serves more than 300,000 businesses across the continent [Paystack Blog]. This month, it is repackaging itself for the next decade.
The new wrapper is called The Stack Group, a holding company that pulls Paystack together with Zap, Paystack Microfinance Bank, and an in-house R&D arm called TSG Labs [Techpoint Africa, Businessday NG]. The thesis is straightforward: payments was the wedge, and the wedge is now wide enough to push into banking, consumer finance, and adjacent product bets. For a company that spent its first decade defined almost entirely by merchant acceptance, it is a notable widening of scope.
The bet
Paystack's core product remains an API that lets African businesses accept cards, bank transfers, and mobile money on their websites and apps [Paystack Docs][Crunchbase]. The pitch to a Lagos e-commerce founder or a Nairobi SaaS startup is the one Stripe perfected in San Francisco a decade ago: a few lines of code, predictable fees, and a dashboard that actually works. The difference is that Paystack built it for a market where card penetration is uneven, settlement rails are fragmented, and cross-border currency handling is a daily operational headache.
The company has leaned into that local complexity rather than around it. Its support documentation walks merchants through accepting USD-denominated cards while paying out in local currency [Paystack Support], a workflow that matters enormously for African businesses selling to diaspora customers or international clients. Starter Businesses, a program for unincorporated sellers, partners with legal startups like DIY Law to walk founders through formal incorporation [Paystack Blog]. These are not glamorous features. They are the kind of unglamorous work that compounds.
Why it could be big
Paystack was Y Combinator's first Nigerian investment, and it remains the cleanest case study for what a Sub-Saharan fintech can become with patient capital and the right distribution partner [Wikipedia]. After a $1.3 million seed in 2016 [Crowdfund Insider] and an $8 million Series A led by Stripe in 2018 [PYMNTS], Stripe acquired the company in October 2020 in a deal reported at roughly $200 million [Global.vc]. The cap table reads like a who's who of patient global capital: Stripe, Y Combinator, Tencent, Visa, Comcast Ventures, and Singularity Investments.
Seed 2016 | 1.3 | $M
Series A 2018 | 8 | $M
Stripe acquisition 2020 | 200 | $M
The upside case rests on two tailwinds. First, African digital commerce is still early. The continent's online transaction volumes are growing from a low base, and a processor that already handles a fifth of Nigeria's online flows [Paystack] is well placed to ride that curve. Second, Stripe ownership gives Paystack something its local competitors cannot easily replicate: access to a global merchant network that wants African payout capability, and engineering resources to keep building when local funding cycles tighten. The Stack Group structure suggests the team intends to use that backing to push into higher-margin adjacencies. A microfinance bank license is not a small thing. Neither is a labs group with an explicit AI mandate.
The team and traction
Akinlade and Olubi met as computer science students at Babcock University and built Paystack together from 2015 onward [LinkedIn][Wikipedia]. Akinlade, who previously co-founded the Nigerian enterprise software company Precurio [Startup Guide], has remained the public face of the business and has expanded his footprint into other ventures, including Sporting Lagos football club [Business Insider Africa]. Headcount sits at roughly 260 as of mid-2025 [LeadIQ, June 2025], modest for a processor of this scale and consistent with a company that has prioritized engineering density over sales sprawl.
The leadership picture changed in November. Co-founder and CTO Ezra Olubi was suspended on November 13, 2025 pending an investigation into allegations of sexual misconduct, and was subsequently fired before that investigation concluded [BBC News Pidgin][TechCabal]. It is a significant transition for a company whose engineering culture has long been associated with both founders. How The Stack Group fills the technical leadership gap, and how it communicates that to merchants and regulators, will shape the next several quarters.
The honest counterfactual
What bears point to is competitive pressure. Flutterwave and Interswitch are not standing still, and both have built meaningful merchant footprints across the same corridors Paystack serves. Flutterwave in particular has pursued an aggressive cross-border strategy and has raised at valuations that put it in a different funding weight class. The argument from skeptics is that being a Stripe subsidiary, while financially comfortable, can slow the kind of regional product bets a fully independent competitor will make faster. What bulls answer, with evidence, is that Paystack's measured pace has produced durable infrastructure: roughly 20% of Nigerian online transactions [Paystack], a 300,000-merchant base [Paystack Blog], and now a holding-company structure designed to let Zap, the microfinance bank, and TSG Labs move on their own clocks without disturbing the core processor.
What to watch
The next twelve months are about whether The Stack Group is a real operating thesis or a brand exercise. Watch for three things. First, product launches out of TSG Labs that demonstrate the AI mandate is more than a line in a blog post. Second, growth metrics from Paystack Microfinance Bank, which is the most concrete signal of how serious the consumer-finance push is. Third, the resolution of the Zap naming dispute, which has already produced public friction with another African company using the same brand [Business Insider Africa]. None of these are existential. All of them will tell investors and merchants whether the second decade looks like the first.
African payments has spent a decade waiting for its defining infrastructure company. Paystack has the clearest claim. The question for readers: when The Stack Group ships its first product that is not a payment button, will African merchants buy it from the same vendor that processes their checkout, or will they shop the category fresh?
