Who We Are

Built for the Scrutiny Fintech Demands

API Solutions was established to address a specific gap: fintech teams preparing for high-stakes moments who need independent, technically rigorous codebase review.

Our Background

We Come From Inside the Problem

The team at API Solutions has spent years working within financial technology development. Not as consultants observing from a distance, but as engineers building the kinds of systems we now audit.

That background shapes how we work. We know which shortcuts feel reasonable under deadline pressure. We know which architectural decisions look fine in development and become liabilities in production. We know what due diligence reviewers look for because we have been on both sides of that conversation.

This is not a generalist security firm that occasionally reviews fintech apps. Our entire focus is financial technology codebases. That specificity matters when the findings need to hold up to technical scrutiny from investors or regulators.

How We Operate

The Principles Behind Our Work

01

Independence First

We have no stake in the outcome. Our findings reflect what we observe in the code, not what a client wants to hear. That independence is the entire value of an external audit.

02

Documentation Over Verbal Briefings

Everything we find is written down with specifics: file paths, line references, code samples where relevant, and clear remediation guidance. Verbal summaries fade. Written findings persist through the development process.

03

Severity That Means Something

We use a severity framework that distinguishes between critical issues requiring immediate attention and lower-priority observations that are worth addressing over time. Not everything is urgent. Some things are.

04

Confidentiality Without Exception

Codebase access is handled under strict NDA. We use read-only repository access. We do not retain code samples beyond the audit period. The security of your intellectual property is treated as seriously as the security of your application.

Our Specialisation

Why Fintech Specifically

Financial technology applications carry a different risk profile than most software. They handle regulated data. They integrate with banking infrastructure. They operate under compliance frameworks that vary by jurisdiction but share a common expectation: that the technical implementation matches the promises made to users and regulators.

A generic code review does not account for this context. Our audit methodology is built around the specific concerns that arise in fintech: PCI-DSS-relevant data flows, KYC/AML process integrity, open banking API security, financial transaction consistency, and the particular ways that authentication failures manifest in payment-adjacent systems.

We also understand the funding context. Technical due diligence during a Series A or B process is not the same as an internal sprint review. The findings need to be credible to a technical investor or their appointed reviewer. Our reports are structured with that audience in mind.
