Mono closed out March with what the company clearly intends as a gift for businesses walking into the second quarter. Mono Sweep, launched in the final days of the month, is a smart money-sweeping service that allows lenders to set up mandates across multiple bank accounts tied to a customer’s BVN, then automatically sweep whichever account has funds on repayment day.
For anyone not familiar with Mono, the company was founded in 2020 and its technology lets users consent to sharing their banking information, giving financial institutions insights into income, spending habits, and repayment ability, much like Plaid’s model in the United States. The company claims to have powered more than 8 million bank account linkages, covering roughly 12% of Nigeria’s banked population, and to have delivered 100 billion financial data points to lending companies. Its customers include Moniepoint and PalmPay. The company is backed by Y Combinator, and its Delaware-registered parent company is named Relentless Labs.
The man behind it is Abdulhamid Hassan, one of the more quietly compelling founders in African fintech. Hassan’s tech journey began in Ijebu Ode, Ogun State, where his late father ran a rental business with an obsessive attention to detail and his mother, a fashion designer, was his first teacher on how product design could evoke trust. He carried both lessons into Mono. Mono is the only work experience listed on his LinkedIn profile. “That’s because Mono is my life’s work,” he has said. His ambition has never been modest. His stated goal is that no fintech application in Nigeria should exist without Mono powering at least one feature inside it.
Beyond the core open banking product, Mono has built a suite of infrastructure tools that have become load-bearing parts of Nigeria’s fintech stack. Connect, its flagship API, enables businesses to access real-time bank data including balances, transactions, statements, income, and identity. DirectPay allows businesses to collect bank transfer payments directly from customers without card infrastructure. Statement Pages lets lenders collect financial histories via a shareable link. More recently, Hassan launched Owo, a product that lets anyone make a payment by sending a WhatsApp message, with approval from Meta to operate as a financial service provider on the platform, while also extending to iMessage and Telegram.
That track record is partly why, in January 2026, Flutterwave acquired Mono in an all-stock deal. The transaction was valued at between $25 million and $40 million, with early backers seeing paper returns of up to 20 times their original investment. For Flutterwave, the deal deepened its vertical integration. In addition to payments, the company can now offer onboarding and identity checks, bank account verification, data-driven risk assessment, and one-time or recurring bank payments within a single stack.
Despite the acquisition, Flutterwave and Mono have been clear that Mono operates as a fully independent product with its own team, roadmap, and brand intact. Mono Sweep is Mono’s own launch, built on its own infrastructure, not a Flutterwave product wearing Mono’s clothing. The acquisition gives Mono access to Flutterwave’s continental scale and licensing footprint across more than 30 African markets. The day-to-day building still happens inside Mono.
On its face the product is a straightforward infrastructure play. Nigerian borrowers increasingly hold money across multiple accounts, salary accounts, savings wallets, fintech accounts, mobile money, and when lenders attempt to debit a primary account that happens to be underfunded, repayment fails even when the borrower has sufficient liquidity sitting elsewhere. Mono Sweep fixes that. With a single authorisation flow, lenders gain the ability to chase the money to wherever it actually lives.
The product is well-designed, the problem it solves is real, and the pricing is accessible. Setup is ₦500 once. Mandate activation is ₦100 per linked account. For a legitimate digital lender managing thousands of loan accounts, this is the kind of infrastructure that meaningfully reduces non-performing loan rates without requiring manual recovery operations.
It is also, depending entirely on who deploys it, one of the most aggressive debt collection tools ever made available to the Nigerian lending market.
What Mono Sweep Actually Does
The technical mechanics matter before the legal and ethical questions can be asked properly.
When a borrower applies for a loan through a lender using Mono Sweep, they go through an authorisation flow in which they approve mandates on their accounts. Customers verify account ownership using their login credentials and transfer a ₦50 authorisation fee to a NIBSS account. There is no limit to the number of linked accounts. The mandates cover any supported bank account tied to the borrower’s BVN.
On repayment day, the lender attempts the primary account first. If funds are insufficient, the system automatically moves to the next linked account, and then the next, until recovery succeeds or all accounts are exhausted. Lenders do not need to intervene manually. The sweep happens in the background, across the borrower’s entire financial footprint, until the debt is collected or the options run out.
Mono is explicit that accounts cannot be debited without authorisation, and that the entire flow operates on explicit customer consent. That consent clause is the load-bearing wall of the entire product. It is also the clause that deserves the most scrutiny.
The Consent Problem
Consent in Nigerian digital lending has a complicated history. The FCCPC’s 2022 Limited Interim Regulatory Framework for Digital Money Lenders was partly a direct response to lending apps extracting data permissions, contact list access, and debit authorisations from borrowers through terms and conditions that were either incomprehensible, presented under financial pressure, or both.
The CBN’s Consumer Protection Framework requires that financial service providers ensure customers fully understand the terms of any product before authorisation is granted. The FCCPC’s guidelines specifically require that digital lenders obtain informed, freely given consent for any payment or data access mechanism.
The question Mono Sweep raises is not whether consent exists in the technical sense. The authorisation flow produces a consent record. The question is whether a borrower sitting across from a loan application that requires BVN-linked multi-account mandate authorisation as a condition of disbursement is in a position to give consent that meets the standard the law actually requires.
For a borrower who needs ₦300,000 for rent or a medical emergency, the gap between clicking “I authorise” and actually understanding that a lender will now have the infrastructure to sweep any account connected to their BVN until a debt is recovered is not a small gap. It is the gap that has historically defined predatory lending in every jurisdiction where it has been litigated.
Where Legitimate Lenders End and Loan Sharks Begin
Mono Sweep is not designed for loan sharks. It is designed for legitimate digital lenders with proper CBN licensing, clean KYC processes, transparent interest rate disclosures, and responsible lending frameworks. For those institutions, it is a genuine infrastructure improvement. Borrowers with good intentions who simply move their salary to a savings account before repayment day no longer get marked delinquent. That is a reasonable outcome.
The problem is that Mono Sweep, as a product, cannot verify the character of the lender deploying it. Nigeria’s digital lending market includes CBN-licensed microfinance banks and finance companies operating within a regulated framework. It also includes a significant number of unregistered loan applications, many operating under the FCCPC’s interim framework or outside it entirely, with interest rates that routinely exceed 100% annually and a documented history of contacting borrowers’ contacts and employers when repayments fail.
A loan shark with access to Mono Sweep does not need to call your contacts. It does not need a field recovery agent. It does not need to send threatening SMS messages. It needs the authorisation flow completed at disbursement, and then it can systematically drain every account connected to your BVN on repayment day without any further interaction. That is not a hypothetical misuse case. It is the logical application of the product’s core function by a bad actor with access to it.
The BNPL sector sits in a similarly grey space. Buy Now Pay Later in Nigeria is growing rapidly and largely unregulated as a distinct product category. Several BNPL providers operate under existing frameworks that do not specifically address the consent requirements for multi-account sweeping mandates. Mono’s own documentation explicitly names BNPL repayments as a primary use case for Mono Sweep. Whether the consent standards currently required of BNPL providers are sufficient to render BVN-linked multi-account sweeping legal under the FCCPC’s framework remains untested.
What The Regulations Say, And What They Don’t
The CBN’s e-mandate framework, administered through NIBSS, governs how electronic direct debit mandates are issued and executed in Nigeria. The framework requires that mandates be authorised by the account holder and that the terms of the debit be clearly communicated. Mono Sweep’s authorisation flow satisfies the technical requirements of that framework, which is why the product is operable.
What the CBN’s e-mandate framework was not designed to address is the scenario of a single lender holding active mandates on every bank account linked to a borrower’s BVN simultaneously. The framework was built for single-account direct debit authorisations. Mono Sweep is technically executing multiple such authorisations in a coordinated sweep, which is a novel use of the infrastructure that the existing regulatory language does not directly speak to.
The FCCPC’s digital lending guidelines require that recovery practices not constitute harassment, that consumers retain the right to revoke consent, and that the scope of any debit authorisation be fully disclosed. Whether sweeping all BVN-linked accounts qualifies as full disclosure under those guidelines depends entirely on how the consent language is drafted in the lender’s application flow, which Mono does not control.
The Nigeria Data Protection Act 2023, administered by the NDPC, is also relevant. BVN-linked account data is sensitive financial data. Using it to locate and debit multiple accounts associated with a single person arguably constitutes processing of financial data beyond the original purpose for which BVN was issued by NIBSS, which is identity verification, not debt recovery. That argument has not been tested in a Nigerian court, but it is a live question.
The Infrastructure Is Not The Problem
Mono built a product that solves a genuine and documented problem in Nigerian lending infrastructure. The consent flow is real. The authorisation mechanism is built on the CBN-approved NIBSS e-mandate system. The product documentation is transparent about how it works.
The problem is that Nigerian financial regulation has not kept pace with the speed at which Nigerian fintech is building, and the gap between what is technically permissible under existing frameworks and what is actually safe for consumers is wide enough to drive a loan recovery operation through.
What is needed, and what does not yet exist, is a specific regulatory framework that addresses multi-account sweeping mandates directly, sets clear disclosure standards for how they must be presented to borrowers, defines the categories of lenders authorised to deploy them, and establishes the consumer’s right to limit sweep authorisation to a subset of their accounts rather than the entirety of their BVN-linked financial footprint.
Until that framework exists, Mono Sweep is legal, functional, and available to every lender that can access Mono’s API, whether they deserve that access or not.
