Capabilities

What we build

Money movement, risk, and operations workflows designed for clear controls and human review.

AI fraud detection

Real-time transaction monitoring, anomaly detection, risk scoring, alert routing, and case-management interfaces, built on infrastructure that holds up under regulator scrutiny.

AI credit underwriting

Credit scoring engines with alt-data ingestion (bank, social, transactional), decision-explainability layers, and regulatory audit trails, engineered to survive fair-lending review.

AI KYC / AML automation

Document intelligence for passports, IDs, and utility bills; face-match flows, sanctions screening, ongoing monitoring, and audit logging, wired to the vendors regulators expect to see.

AI document intelligence

Loan documents, contracts, invoices, and receipts processed through OCR + LLM extraction with structured-output validation, production-grade enough to drive the decisions that follow.

AI compliance automation

Regulatory rule engines, transaction-monitoring rule sets, automated regulatory reporting, and audit trails (AML, sanctions, FATCA, MiFID II), built with the controls examiners ask about.

AI investment & advisory

Robo-advisor platforms, portfolio rebalancing engines, AI research summarisation, and conversational portfolio analysis, engineered for the suitability and disclosure workflows your use case requires.

AI treasury & cash-flow tools

Cash-flow forecasting models, treasury workflow automation, multi-currency reconciliation, and banking integrations, built for finance teams operating across many banking systems.

Embedded finance platforms

BaaS layer integrations, embedded payments, embedded lending, and KYC pipelines, wired into the licensed partners that hold the regulatory permissions, with the application layer in your control.

Secure payment card terminal with PIN entry

Every transaction, one traceable decision at a time

Financial analyst reviewing market data across multiple displays

Financial systems in motion

Financial workflows need evidence at every decision

Money movement, identity checks, and risk decisions share one constraint: each outcome needs a clear reason, a human review path, and an audit record.

A note from the founder

From the founder

I started Robust Devs in 2019 after watching too many good products die between agencies. The pattern was always the same: big promises in the sales call, silence by week six. We built this firm to be the opposite of that. A small senior team, honest scope, and the uncomfortable truth delivered early.

If you are building in marketing, healthtech, or fintech, tell me what you are working on. If we are not the right team for it, I will say so on the first call and point you somewhere better.

  • Not yet. SOC 2 Type II is planned, with a target window of late 2026. The internal controls library that underpins it is already in place, and we can share the control-mapping evidence under NDA if your security review needs it before the report lands.
