Fintech

Building a fintech product is hard — compliance, security, and scale must all work together from day one.

Fintech startups and established financial technology companies face a unique challenge: they must build products that are innovative and frictionless for users while simultaneously meeting the stringent security and regulatory requirements that govern financial services. Moving fast while maintaining compliance is technically demanding, and many fintech products stall because the engineering team underestimates the complexity of payment rails, KYC flows, or regulatory reporting. Kiloctet builds fintech products with compliance and security baked in from the architecture stage, so you can ship fast without accumulating technical debt that blocks scale.

What we build

Fintech software solutions we provide

01

Digital Wallet and Payment Application

A mobile-first payment application supporting peer-to-peer transfers, bill splitting, merchant payments, QR code transactions, and virtual card issuance. The wallet integrates with payment networks and banking APIs to fund accounts via bank transfer or card top-up, and supports multi-currency balances for international use cases. Security layers include biometric authentication, device binding, transaction limits, and real-time fraud screening to protect users without adding unnecessary friction.

02

Lending and Credit Decisioning Platform

A technology platform for digital lenders covering loan application intake, automated credit scoring using alternative data sources, decisioning engine configuration, offer presentation, e-signature, disbursement, and repayment management. Alternative credit scoring models assess applicants who lack traditional credit bureau profiles by incorporating transaction history, behavioral data, and verified income signals. The platform is configurable for consumer installment loans, business credit lines, BNPL products, and payday-style short-term credit.

03

Embedded Finance and BaaS Integration Layer

An API-first integration layer that allows non-financial businesses to embed banking, lending, insurance, or payment products into their existing apps and platforms using your fintech infrastructure. The layer abstracts banking partner APIs, handles regulatory compliance, and provides developer-friendly SDKs that partner businesses can integrate without deep financial services expertise. Webhook-based event notifications keep partner platforms synchronized with transaction and account state changes in real time.

04

RegTech Compliance and AML Monitoring Platform

A compliance technology platform that automates customer due diligence, transaction monitoring, suspicious activity reporting, sanctions screening, and regulatory reporting for fintech companies operating under financial services licenses or e-money regulations. Rules-based and machine learning-assisted detection models identify transaction patterns associated with money laundering, fraud, or account takeover. Case management workflows guide compliance analysts through investigation and reporting processes with full audit trails.

05

Personal Finance Management (PFM) Platform

A data aggregation and analytics layer that pulls transaction data from multiple bank accounts and financial products via open banking APIs, categorizes spending, and surfaces insights, budgets, and financial health scores for users. The platform powers advice-led features — savings recommendations, debt payoff calculators, investment readiness scores — that differentiate financial apps beyond basic balance display. Personalization improves as the model learns from user behavior and feedback over time.

Why bespoke

Benefits of building bespoke solutions

01

Faster Time to Market Without Compliance Debt

Fintech products built with compliance infrastructure from the start — KYC flows, transaction monitoring, audit logging, data residency controls — avoid the costly rework that occurs when these requirements are bolted on after launch. Regulatory requirements that are integrated into the core product architecture are also easier to maintain as regulations evolve. Teams that treat compliance as an engineering concern from day one consistently reach scale with fewer regulatory setbacks than those who treat it as an afterthought.

02

Superior User Experience Driving Conversion and Retention

In fintech, onboarding conversion and product stickiness are directly tied to how seamless and trustworthy the user experience feels. A well-designed KYC flow that completes in under three minutes, a payments experience that works first time every time, and a clean, transparent fee structure all contribute to conversion rates that determine whether the business grows. Investing in UX quality at the product level is consistently among the highest-ROI investments a fintech can make.

03

Reduced Fraud and Financial Crime Exposure

Custom transaction monitoring and fraud detection rules tuned to your specific product and customer base outperform generic off-the-shelf solutions that generate high false positive rates, frustrating legitimate customers. Machine learning models that learn from your transaction patterns continuously improve detection accuracy over time. Reducing fraud losses directly improves unit economics, and maintaining clean transaction monitoring records reduces regulatory risk and the cost of audits.

04

Scalable Infrastructure for Rapid Growth

Fintech products can grow from thousands to millions of users very quickly if the market responds, and the infrastructure must scale to match without requiring expensive re-architecture. Cloud-native architectures with microservices, asynchronous processing for payment events, and horizontally scalable databases handle growth without the performance degradation that monolithic systems experience. Building for scale from the start is cheaper than re-platforming under pressure during a growth phase.

05

Robust API and Partner Ecosystem Capabilities

Modern fintech products increasingly derive value from their ability to integrate with banking partners, payment networks, data providers, and distribution partners via APIs. A well-designed API layer makes it possible to swap underlying banking providers, add new payment methods, or onboard distribution partners without rebuilding the product. This flexibility reduces vendor lock-in and allows the product to evolve as the market and regulatory landscape changes.

Common questions

FAQ

Regulatory compliance in fintech is not a single checkbox — it varies by product type, jurisdiction, and license held. We start every fintech engagement with a compliance scoping session to map the regulatory requirements that apply to your product: PSD2 and e-money regulations in Europe, FCA requirements in the UK, CSSF in Luxembourg, Bank Al-Maghrib requirements in Morocco, or the relevant framework in your market. These requirements are translated into technical specifications — KYC flow completeness, data retention periods, transaction monitoring rules, reporting obligations — that become part of the product design. We document compliance-relevant design decisions to support regulatory applications and audits.
Yes. We integrate with payment rails through banking partner APIs, payment processor SDKs (Stripe, Adyen, Checkout.com), and direct scheme connections where appropriate. SEPA Credit Transfer and Direct Debit, SWIFT international wires, UK Faster Payments, and local real-time payment schemes across Africa and the Middle East are all integration patterns we have experience with. The specific approach depends on whether you hold a payment license directly or are relying on a licensed banking partner's infrastructure. We advise on the most cost-effective and compliant integration architecture based on your product requirements and transaction volumes.
We integrate with leading identity verification providers including Jumio, Onfido, Sumsub, and Smile ID for automated document verification and biometric checks. For markets where government ID verification APIs are available, we integrate directly with national identity systems to provide instant verification. The KYC flow is designed to balance regulatory thoroughness with user experience — minimizing drop-off at verification steps while collecting all required evidence. Risk-based approaches apply enhanced due diligence only to higher-risk customer segments, keeping the onboarding experience smooth for the majority of applicants.
Fintech applications require security measures significantly beyond standard web application practices. Every transaction operation is authenticated with strong customer authentication (SCA) compliant with PSD2 or equivalent local standards. All sensitive data — account numbers, card details, identity documents — is encrypted at rest and never stored in logs. API access uses short-lived tokens with narrow scopes. Fraud detection rules screen transactions in real time before authorization. We conduct threat modeling during design, static analysis during development, and penetration testing before launch. Post-launch, security monitoring and alerting detect anomalies continuously.
Yes, and this is a specific focus of how we scope fintech projects. A compliance-ready MVP is achievable faster than most teams expect when the scope is focused on a single well-defined use case — one loan product, one payment corridor, one user segment — with compliance requirements built in from the start rather than retrofitted. We help fintech founders make scope decisions that preserve compliance integrity while minimizing time to first transaction. Our fintech MVP engagements typically run twelve to twenty weeks depending on regulatory complexity and the number of third-party integrations required.
