Fintech AI

Financial AI that regulators won't flag.

From fraud detection to credit scoring to regulatory reporting - we build financial AI systems with the explainability, auditability, and compliance posture your regulators expect.

What we build

Fraud Detection

Real-time transaction scoring, anomaly detection, and adaptive fraud pattern recognition. Sub-100ms inference latency for card-present and digital transactions.

Real-timeGraph MLAdaptive

Credit Risk Scoring

Alternative data credit models, LTV prediction, and scorecard development - with SR 11-7 compliant model documentation and validation evidence.

Batch scoringAlternative dataExplainable

Document Intelligence

LLM-powered extraction from financial contracts, statements, invoices, and regulatory filings. Structured output with confidence scoring for downstream automation.

LLMOCRRAG

Regulatory Reporting

Automated data pipelines for CCAR, stress testing, FINREP, and AML reporting - reducing manual compilation time by 80–95% across reporting cycles.

AutomationData pipelinesAudit trail

Trading & Risk Analytics

Market microstructure analysis, portfolio risk dashboards, and signal generation pipelines for quant teams - with real-time data ingestion from major exchanges.

Compliance architecture

Explainability

  • Model cards for every production model
  • SHAP-based feature attribution
  • Adverse action notices (FCRA-compliant)
  • Audit trails from input to decision
  • Plain-language model documentation

Data Security

  • AES-256 encryption at rest
  • TLS 1.3 in transit
  • Tokenisation for PII and financial data
  • Key management (HSM / AWS KMS)
  • SOC 2 Type II audit-ready architecture

Regulatory Alignment

  • SR 11-7 model risk management framework
  • EU AI Act high-risk system controls
  • Fair lending analysis (ECOA / Reg B)
  • GDPR data subject rights implementation
  • MiFID II record-keeping requirements

Real-time vs batch

The right architecture depends on your latency requirements. We help financial teams choose correctly - before they build wrong.

Real-time

< 100ms P99

Use cases

Fraud detection, transaction monitoring, AML screening

Millisecond decisioning required before transaction settlement. Latency directly impacts customer experience and fraud loss rates.

Batch / Near-real-time

Minutes to hours

Use cases

Credit scoring, risk reporting, model retraining

Accuracy requirements outweigh latency constraints. Larger feature sets and more complex models are viable when seconds or hours are acceptable.

Model risk management

SR 11-7 sets the standard for model risk management in US financial services. We build to it - not around it.

Model Inventory

All production models documented with intended use, risk tier, performance benchmarks, and review schedule.

Independent Validation

Model validation performed by team separate from development. Replication of key results, challenger model comparison, and sensitivity analysis.

Ongoing Monitoring

Production model performance tracked against PSI, CSI thresholds. Automated alerts on drift. Scheduled revalidation on defined triggers.

Governance Committee

Model approval, exception management, and retirement decisions escalated to governance committee with documented sign-off.

Case Study - Fintech

"LLM contract review pipeline saving £2.1M/year for a UK insurance broker."

RAG-powered extraction from policy documents, endorsements, and cover notes. Replaced a 12-person manual review team. Full audit trail on every extraction decision - GDPR compliant, MiFID II record-keeping aligned.

The comparison

Without AI vs. with StartxLabs.

Capability
Without AI
With StartxLabs

Fraud detection

Rule-based systems with 15–20% false positives; requires manual review queues

ML scoring at < 80ms with adaptive pattern recognition; false positives reduced 83%

Credit decisioning

Traditional scorecards; days to decision; limited to bureau data

Alternative-data models; real-time decisioning; explainable adverse action notices

Regulatory reporting

Manual data compilation across 12+ systems; 80+ analyst hours per cycle

Automated pipelines; CCAR and FINREP data reconciled in hours with full audit trail

Document review

Human analysts reading contracts line by line; 3–5 days per batch

LLM extraction with structured output; batch processed overnight; 99%+ field coverage

AML screening

Keyword-match rules; high alert volumes; limited typology coverage

Graph ML + NLP screening; adaptive to new typologies; alert volumes reduced by 60%
