What We Do
AML & Financial Crime Advisory for UK, EU & Africa Payment Corridors
We help banks, fintechs, and payment institutions manage financial crime risk across multiple jurisdictions, from cross-border payments and correspondent banking to trade finance and trade-based money laundering. Whether you are securing a licence, responding to regulatory pressure, or scaling into new markets, we deliver clear, actionable, and regulator-ready solutions.
The Challenge
Operating across borders has never been more complex.
Firms working across UK, EU, and African markets face a convergence of pressures that standard compliance functions are not built to absorb
- Increasing regulatory scrutiny across multiple jurisdictions with differing AML and sanctions frameworks
- Evolving financial crime threats that exploit cross-border payment flows and trade corridors
- Pressure to scale efficiently while maintaining robust controls and transaction monitoring
- The need to protect and maintain correspondent banking and trusted institutional relationships
Getting these wrong carries serious consequences — regulatory censure, licence risk, reputational damage, and loss of banking access. Getting it right requires more than a generalist compliance team.
This is not a secondary market for us. It is the primary market we work in — and that focus is what makes our advice reliable, specific, and immediately applicable.
Our Approach
Practical. Scalable. Defensible. Targeted.
Every engagement is shaped around your business model, risk profile, and the specific corridors you operate in. We do not apply standard frameworks to non-standard problems.
Our solutions are designed to be:

Team Credentials
Nana Mantey
Founder | AML, Financial Crime & Regulatory Compliance — UK, EU & Africa
Nana brings more than 15 years of retail, corporate, and correspondent banking experience, combined with over 8 years of regulatory consulting advising banks, fintechs, e-money institutions, and payment firms operating across UK and Sub-Saharan African markets. With deep knowledge of FCA regulatory expectations, AML and CTF frameworks, and the correspondent banking and remittance ecosystems connecting the UK and Africa, Nana provides guidance that is both regulator-ready and operationally grounded.
What Set Us A Part
Expertise Where It Counts. Experience Across the Full Spectrum.
Unlike generalist compliance consultancies, we operate at the intersection of UK/EU regulatory rigour and African market expertise, a combination few advisory firms genuinely offer end to end. Our team brings together over 15 years of retail, corporate, and correspondent banking experience with deep knowledge of the regulatory environments, payment flows, and institutional relationships that define UK ↔ SSA corridors.
We have worked with high-growth fintechs building compliance frameworks from the ground up and with established banks responding to supervisory findings and audit scrutiny. What sets us apart is not just what we know — it is how we work. We bridge strategy, regulation, and operational execution, so advice translates into frameworks your teams can implement, your regulators can examine, and your business can grow within.
Who We Work With
Built for Firms Where Compliance Complexity Is the Norm
We work with organisations that operate in high-scrutiny environments, serve cross-border client bases, or are navigating the specific demands of UK, EU, and African financial markets.
Fintechs & Payment Startups | Rapidly scaling businesses that need financial crime frameworks capable of supporting growth, licence applications, and institutional partnerships, without slowing commercial momentum. |
Banks & Correspondent Institutions | Established financial institutions managing correspondent relationships, de-risking pressures, or supervisory findings that require specialist input beyond internal resource. |
PSPs, EMIs & MSBs | Regulated payment firms operating across multiple jurisdictions that need practical, regulator-ready compliance frameworks aligned to their transaction volumes and risk exposure. |
Venture Capital & Investor-Backed Firms | Investors and portfolio companies seeking financial crime due diligence, pre-investment compliance assessments, or post-investment remediation support. |
Firms Across UK–Africa Corridors | Any institution, at any stage, with exposure to Sub-Saharan African markets, diaspora payment flows, or cross-border trade finance that demands specialist corridor knowledge. |
African Financial Institutions | Local banks, rural & community banks, and microfinance institutions across West and Sub-Saharan Africa seeking to build or strengthen AML/CTF frameworks aligned to FATF standards. |
Our Approach
Practical. Scalable. Defensible. Targeted.
Every engagement is shaped around your business model, risk profile, and the specific corridors you operate in. We do not apply standard frameworks to non-standard problems.
