About Banke Ajayi

Twenty years of quant risk and data systems. Then a deliberate decision to consolidate that knowledge and experience in Ahjayee.

Ahjayee was not a pivot. It was a conclusion — reached after two decades watching how data infrastructure creates compounding competitive advantage at scale, and a growing conviction that businesses deserved the same foundations. I started building in 2025. The work is now.

The journey

The sequence is the credential.

Quant risk teaches you something that some consultants miss: how to make high-stakes decisions from imperfect, incomplete data. You build models not because the data is clean, but precisely because it is not — and the discipline is in knowing what the model can and cannot tell you.

That thinking is directly transferable to what businesses face today. They are sitting on years of transaction data, customer records, and operational history — most of it unstructured, some of it inconsistent, all of it underused. The question is not whether the data is perfect. The question is what can be built on what exists.

Starting Ahjayee in 2025 was not a career change. It was the application of two decades of pattern recognition to a market that has been waiting for exactly this approach.

The businesses that win with AI will not be the ones that waited for perfect data. They will be the ones that started building with what they had.

The point of view

AI is not the strategy. It is the outcome of getting the strategy right.

Businesses has been accumulating data for years, in spreadsheets, WhatsApp threads, accounting software, mobile money records. That data is a latent asset. Most businesses do not know what they have or how to use it.

The work Ahjayee does is not about technology adoption. It is about building the operational and data foundations that make AI genuinely useful then building the intelligence layer on top of data the business already owns. That is a competitive advantage that compounds, and one that cannot be replicated by a competitor who simply bought the same software.

The work in practice

Built, not theorised.

The platforms below were not built as consulting props. They were built to solve real problems in the African SME context and every lesson from building them informs the client work.

Identity layer

Find A Biz Africa

Verified SME discovery and identity infrastructure. Custom search engine built around Nigerian business context, trust signals, and cultural synonym expansion.

Transaction layer

YouSabiSell

WhatsApp-native social commerce and order management. Built around how African SMEs actually transact.

Records layer

BizTraka

Business management PWA with local-first architecture. Invoicing, inventory, and financial records designed for the African operating environment.

Intelligence layer

The BFA Framework

The Business Foundation Audit, a structured diagnostic that sequences automation, analytics, and AI implementation according to operational maturity.

SSRN white paper on identity, verification, and the structural barriers to SME growth across African markets.

No One Cares About Your AI Stack

A talk on why African businesses fail at AI adoption — and the four-layer foundation they need to build first. The framework that became the BFA.

No One Cares About Dashboards

On why reporting projects fail and what businesses need before analytics becomes genuinely useful.

Data Foundations — Ahjayee Learn

The BFA methodology as a structured curriculum. Data Foundations is live now. Intermediate and Advanced, with AI implementation, follow in Q2/3 2026.

How the work runs

Active engagements.

Current client work spans fractional CTO engagements and Business Foundation Audit implementations across sectors including healthcare and professional services, all working through the same four-layer methodology.

The methodology is not theoretical. Every observation in the BFA framework has been tested against real businesses with real operational complexity — and refined based on what actually surfaces during discovery.

The right starting point is an honest conversation.

The first call is not a sales pitch. It is an assessment of where your business currently stands, what data you already have, and whether the Business Foundation Audit is the right next step. If it is not, I will tell you that.
