Industry - Fintech

Engineering for systems where getting it wrong shows up in a regulatory filing.

Risk, fraud, payments, and compliance-heavy workflows. We understand regulated systems, audit trails, and the difference between a model that works and one that compliance will sign off on.

Compliance note

We are an engineering firm, not a compliance consultancy. We build systems that are designed to be compliant - with full audit trails, explainable decision paths, and human-in-the-loop controls where required. Final compliance sign-off is with your legal and risk teams.

Where we help

The engineering problems we see most in fintech.

These are not hypothetical. They come from audits and engagements with funded fintech companies across payments, lending, and compliance-adjacent SaaS.

Fraud and risk systems that do not scale

Rules-based fraud engines hit diminishing returns. ML-based risk models are harder to explain to compliance. You need engineering that understands both sides.

Payments infrastructure held together with duct tape

Integrations built for one provider that now need to support four. Settlement logic that was never designed for current volume. The cost of getting this wrong is not just technical.

Compliance automation that creates more toil than it removes

Reporting pipelines that require manual review. Audit logs that are technically present but practically useless. AML and KYC workflows that slow onboarding without proportionate risk reduction.

AI features that legal will not approve without evidence

LLM-assisted underwriting, document classification, anomaly detection - valuable, but they need explainability, audit trails, and human-in-the-loop design before going near production.

Data infrastructure not built for real-time

Batch pipelines that make risk decisions stale. Event sourcing that was added later and never fully replaced the batch layer. Analytics that cannot answer what the current exposure is.

Platform too fragile to onboard new clients on

Multi-tenancy that was added as an afterthought. Configuration management that is a spreadsheet. Infrastructure that works until a new enterprise client asks about SLAs.

Fintech - Series BRisk & underwriting
Production risk-scoring platform from whiteboard in 14 weeks

A growth-stage lending platform needed an ML-based underwriting model with full auditability - every decision traceable, replayable, and explainable to their compliance team. We built the inference architecture, the eval harness, and the shadow rollout. The system is now serving 11,000 underwriting decisions per day with a full audit trail.

FinTechPlatform modernization
PHP monolith replaced — PCI-DSS Level 1 certified, €12M Series C unblocked

A payments platform processing €40M annual volume was running on a fragile PHP monolith that blocked compliance certification and investor due diligence. We replaced it with an event-driven microservices architecture — achieving PCI-DSS Level 1 certification, cutting transaction latency by 68%, and clearing the technical blocker that enabled the client's Series C close.

FinTechCompliance automation
Customs declarations processed in under 90 seconds — 100% compliance across CDS, CCS-UK, CNS, DEFRA

A customs broker platform was processing declarations manually — hours of work per shipment, with compliance risk at every step. We built automated declaration processing across four UK and EU customs systems, reducing each declaration from hours to under 90 seconds with 99.9% platform uptime and full audit trail.

Client feedback

What clients say about working with us.

We brought Insoftex in after our second failed attempt at productionising the model. In six weeks they rebuilt the inference layer, instrumented it properly, and gave us an eval harness our own team could extend. They told us no twice during the engagement — both times they were right.

We're very happy with the outcome and already looking ahead to the next phase. What stood out most was Insoftex's strong sense of ownership, transparent and fast communication, and ability to think beyond the initial scope to continuously add value. From day one, they supported us in shaping the product vision, through to delivering a high-quality MVP. The result is a robust platform that enables customers to easily book advertising placements and effectively drive visibility and sales. A reliable and forward-thinking partner.

We had a great experience working with the Insoftex team. They played an important role in delivering a modern application for power quality and energy generation analytics, owning both front-end development and automated QA. They built a flexible, user-centric dashboard with configurable widgets, making it easy to analyze data across devices, parameters, and time ranges. Insoftex combines strong technical expertise with a clear focus on quality and delivery. A reliable partner I'd confidently recommend.

Working with Insoftex on the social engagement platform, The Club of Names, was both productive and inspiring. They were involved far beyond development — they helped shape the product's concept and actively contributed ideas that strengthened its core functionality. Together, we built a platform that provides information about names, generates personalized articles, helps users select baby names, and includes a social feature — a chat for people with the same name to connect.
