Africa has more than 500 commercial banks, 200 mobile money operators, and dozens of digital lenders operating across 54 markets with almost no standardised data-sharing infrastructure between them. Emeka Diallo, a Lagos fintech founder building a personal finance management app, spent eight months and USD 45,000 negotiating individual data-sharing agreements with six Nigerian banks before discovering that three of them could not deliver transaction data through any API. AskBiz maps the structural data gaps in African financial infrastructure and helps fintech operators and investors understand where open banking rails exist, where they are emerging, and where the absence of data connectivity creates both problems and platform opportunities.

Five Hundred Banks, Two Hundred Mobile Money Operators, Zero Unified Data Layer#
The African financial services landscape is characterised by extraordinary institutional fragmentation operating without shared data infrastructure. Nigeria alone has 22 commercial banks, 9 merchant banks, over 900 microfinance banks, 5 mobile money operators, and dozens of licensed digital lenders. Kenya adds 39 commercial banks, 13 microfinance banks, and the M-Pesa ecosystem processing over KES 35 trillion annually. South Africa has 19 registered banks plus numerous non-bank financial institutions. Egypt has 38 banks. Across the continent, the total exceeds 500 commercial banks and 200 mobile money operators, each maintaining its own customer data, transaction records, and account systems in proprietary formats with no standardised mechanism for sharing information between institutions or with authorised third parties. In Europe, the revised Payment Services Directive mandated open banking APIs that allow customers to share their financial data with authorised third-party providers. In the United Kingdom, the Open Banking Implementation Entity created technical standards that enable nine major banks to share account and transaction data through standardised APIs. In Brazil, the Central Bank mandated open finance implementation across all major financial institutions. These regulatory mandates created the data infrastructure on which thousands of fintech applications now operate, from personal finance managers and credit scoring engines to account aggregation platforms and automated switching services. In Africa, open banking regulation is in early stages at best and non-existent in most markets. Nigeria published an Open Banking Framework through the Central Bank in 2023, establishing tier classifications for data sharing, but implementation remains uneven. South Africa has no open banking mandate, though the Intergovernmental Fintech Working Group has published discussion papers. Kenya has no formal open banking regulation, though several banks have published developer APIs voluntarily. The result is a continent where a customer financial life is fragmented across five to ten institutions, none of which share data with each other, and where building any application that requires a consolidated view of customer finances demands institution-by-institution negotiation with no guarantee of technical feasibility.
Emeka Diallo and the Eight Months of API Negotiations#
Emeka Diallo is a 33-year-old fintech founder in Lagos building a personal finance management application designed to help Nigerian professionals track spending, manage budgets, and improve savings rates by aggregating their financial data across banks, mobile money, and digital wallets into a single dashboard. The concept is straightforward and proven in developed markets, where apps like Mint, Plaid-connected services, and open banking aggregators serve tens of millions of users. In Nigeria, Emeka discovered that the concept is simple but the infrastructure is brutal. His first step was approaching six Nigerian commercial banks about data-sharing partnerships. Two banks had no external API capability whatsoever, their core banking systems could not expose transaction data to third parties through any technical means short of screen scraping, which both banks explicitly prohibit. Two banks had internal APIs used by their own mobile banking apps but had never exposed them to external partners and required extensive security reviews, legal agreements, and technical integration work before considering access. One bank had a published developer API but it returned only balance data, not transaction history, and rate-limited queries to 100 per day, insufficient for a consumer application. Only one bank offered a reasonably functional API with transaction-level data, but its documentation was outdated, its sandbox environment was frequently offline, and the commercial terms required a minimum annual fee of NGN 12 million before any revenue was generated. Eight months after beginning the process, Emeka had functional data connections to three banks, covering approximately 40 percent of the accounts his target users held. He had spent USD 45,000 on legal fees, technical integration costs, and the minimum API access fees, with no guarantee that the three connected banks would maintain their API availability or terms. Two additional banks were still in legal review. One had stopped responding entirely. Emeka experience is not unusual. It is the standard experience for any African fintech that requires access to financial institution data, and it explains why most African fintech applications either avoid multi-institution data aggregation entirely or rely on screen scraping techniques that are technically fragile and legally questionable.
The Three Layers of Open Banking Infrastructure That Africa Needs#
Building functional open banking in Africa requires three infrastructure layers that interact but serve distinct purposes. The first is the connectivity layer, the technical plumbing that enables authorised third parties to access financial institution data through standardised APIs. This is what companies like Mono, Stitch, and Okra are building in specific African markets, creating middleware that connects to bank core systems and exposes standardised data endpoints that fintechs can integrate against. The connectivity layer must handle the extraordinary heterogeneity of African banking technology. Core banking systems across the continent run on platforms ranging from modern cloud-native systems to mainframe-era installations running COBOL. Some institutions operate on Temenos T24, Finacle, or FlexCube. Others run locally developed systems with idiosyncratic data models. Mobile money operators run on platforms like Ericsson Mobile Financial Services or Huawei Mobile Money with their own data architectures. The aggregator must translate this diversity into consistent data outputs, a task that requires deep institution-by-institution integration rather than a single technical standard. The second layer is the consent and identity framework that governs how customers authorise data sharing. In open banking markets like the UK and EU, standardised consent flows allow customers to grant and revoke data access through regulated processes. In Africa, no equivalent framework exists at scale. Each aggregator must design its own consent mechanism, and customers must trust both the aggregator and the receiving application with access to their financial data. The third layer is the commercial model that makes the infrastructure sustainable. UK open banking was mandated by regulation, with compliance costs borne by banks. In Africa, where regulation does not mandate participation, aggregators must create commercial incentives for financial institutions to open their data. This typically involves revenue sharing on products originated through aggregated data, such as lending products using multi-institution credit assessment, or direct fees charged to fintechs for data access. Each of these layers presents distinct technical, regulatory, and commercial challenges, and the absence of any one undermines the utility of the others.

Regulatory Trajectories Across the Continent#
The regulatory landscape for open banking in Africa ranges from structured frameworks in early implementation to complete silence, and the trajectory in each market will shape the commercial opportunity for aggregator platforms differently. Nigeria is the most advanced, with the Central Bank of Nigeria Open Banking Framework establishing four data-sharing tiers from basic product information to full transaction data. The framework designates the Nigeria Inter-Bank Settlement System as the regulatory body for open banking implementation and requires participating institutions to maintain standardised APIs. However, enforcement mechanisms are not yet fully operational, and bank compliance is uneven. Large banks like Access, GTBank, and Zenith have made meaningful API investments. Smaller banks and microfinance institutions lag significantly. South Africa has taken a market-driven rather than regulatory approach. The South Africa Reserve Bank and the Intergovernmental Fintech Working Group have published consultation papers on open finance but have not issued binding regulations. Meanwhile, South African banks have voluntarily opened APIs through initiatives like Investec Programmable Banking and Standard Bank API marketplace, creating pockets of connectivity without a national framework. Kenya occupies a middle position where the Central Bank has expressed support for open banking principles without issuing specific regulations. The Kenya Bankers Association has facilitated industry discussions, and several banks have published APIs, but standardisation is absent. The M-Pesa ecosystem, which dominates Kenyan financial services, operates with its own API framework through Safaricom Daraja, creating a parallel data-sharing infrastructure outside the banking system. Egypt has introduced digital banking regulations through the Central Bank of Egypt that include provisions for data sharing but focus primarily on licensing new digital banks rather than mandating open APIs from existing institutions. North African markets more broadly, including Morocco and Tunisia, are in early consultative stages. For aggregator platforms, the regulatory trajectory determines the competitive dynamics. In regulated markets, compliance becomes a barrier to entry that protects established aggregators. In unregulated markets, aggregators compete purely on the quality of their bank relationships and technical integrations. The multi-market aggregator that builds regulatory intelligence across all major African markets will have a structural advantage in positioning for regulation as it arrives.
Where AskBiz Fills the Intelligence Gap for Open Banking Operators#
Open banking aggregators and the fintechs they serve operate in an environment where the basic market facts are difficult to establish. How many banks in a given market have API capability? What data fields do those APIs expose? What are the commercial terms? How reliable is uptime? Which mobile money operators allow third-party data access? What regulatory changes are in consultation that could mandate or restrict data sharing? These questions do not have published answers in any consolidated source, and answering them requires the kind of structured market intelligence that AskBiz is designed to provide. For aggregator platform operators like Mono, Stitch, and Okra, AskBiz structures the competitive and regulatory intelligence needed to prioritise market expansion. The Customer Management module tracks bank partnership pipelines, from initial outreach through technical assessment, legal negotiation, integration development, and production launch, providing visibility into where each institutional relationship stands and which are stalling. The Health Score feature monitors the operational health of live bank integrations, flagging when API uptime degrades, data quality drops, or transaction volumes indicate connectivity issues before they affect downstream fintech clients. Decision Memory captures every market entry decision, partnership negotiation approach, and pricing strategy alongside outcomes, building institutional knowledge that prevents repeating mistakes across markets. For fintech founders like Emeka Diallo who depend on aggregator infrastructure, AskBiz provides visibility into which aggregator covers which institutions in each market, what data fields are accessible through each connection, and where gaps in coverage will constrain product functionality. The Daily Brief consolidates regulatory updates, partnership status changes, integration health alerts, and market intelligence into a single operational summary. In an industry where the infrastructure itself is still being built, structured intelligence about the state of that infrastructure is as valuable as the technical connections themselves.
The Platform Opportunity Beneath the Plumbing#
Open banking aggregation in Africa is frequently discussed as infrastructure, as plumbing that enables other applications. This framing, while technically accurate, understates the strategic value that accumulates to the aggregator layer. Every transaction processed through an aggregator generates data about inter-institutional money flows, customer financial behaviour patterns, and the operational quality of connected institutions. Over time, an aggregator processing millions of transactions across hundreds of institutional connections accumulates a dataset that is unique in the African financial landscape, a cross-institutional view of how money actually moves through the economy. This dataset enables products and services that no single financial institution can offer independently. Credit scoring models built on multi-institutional transaction data outperform single-institution models because they capture the full picture of a borrower financial behaviour rather than the slice visible to one bank. Fraud detection systems fed by cross-institutional patterns can identify anomalies invisible within single-institution data. Personal financial management tools powered by complete financial data provide genuinely actionable budgeting and savings recommendations rather than the partial view that single-bank apps can offer. The aggregator that achieves critical mass in bank connectivity and transaction volume in a given market becomes extremely difficult to displace because the value of the dataset compounds with every new connection and every additional transaction. New entrants must replicate years of institution-by-institution integration and data accumulation, a process that cannot be accelerated simply with capital. For investors evaluating the African open banking opportunity, this compounding data advantage is the most important characteristic to assess. The aggregator with the broadest institutional connectivity, deepest transaction history, and most sophisticated data analytics will command the infrastructure layer of African fintech for the coming decade. The market is still early enough that leadership positions are not yet locked, but the window for building foundational connectivity is narrowing as the first movers extend their institutional coverage and the regulatory environment begins to mandate standardised participation.
