From Pilot to Production: How to Scale GenAI with Flexa Cloud and AWS in the Financial Sector 

A Generative Artificial Intelligence (GenAI) It's no longer just a trend; it's become a strategic differentiator in the financial sector. But while many institutions initiate promising pilot programs, few manage to transform these tests into solutions. productive, safe and scalableThe challenge is no longer proving that GenAI works — it's migrating from proof of concept to actual production, with governance, compliance, and measurable ROI. It is precisely at this point that Flexa Cloud, in partnership with AWS, makes the difference.

Why do so many GenAI projects remain in the pilot phase?

Gartner estimates that more than 80% of GenAI projects in financial institutions They don't get past the experimental phase. The reasons are almost always the same — and there is a solution.

• Excessive focus on experimentationWithout a scalability plan, the team tests isolated prompts and use cases without considering how that can be transformed into a product. Result: 6 months of PoC and zero value on the balance sheet.
• Limited infrastructure which cannot handle the transaction volume, required latency, and 24/7 criticality of the financial sector. Local server, idle GPU, instability—all of this kills productivity.
• Lack of data governance and AI...generating absurd regulatory risks. LGPD, Central Bank Resolution 4.658, BACEN, CVM, Susep — without governance, AI becomes a compliance time bomb.
• "Black box" models No traceability, no explanation, no audit. The regulator asks, "Why was this client denied?" and the team has no answer.
• Lack of clear metrics Return on investment. Without defined business KPIs before the pilot, any result becomes a "success"—and no CFO approves the budget to continue.

Without addressing these 5 points, innovation ends up being limited to... Internal tests with no real impact on P&L..

The 3 pillars for scaling GenAI in the financial sector

For GenAI to move from pilot to product, alignment is necessary. three complementary pillars — You can't invest in one and neglect the other two.

1. Reliable and secure cloud infrastructure Elastic computing, storage, and networking resources (AWS Bedrock, SageMaker, EKS) are essential to support growth without compromising performance, latency, or cost. Dedicated private cloud for sensitive workloads, multi-AZ for resilience, end-to-end encryption.
2. Training and fine-tuning of models Adapting pre-trained models (Bedrock, Claude, Llama) to the financial context with RAG (Retrieval-Augmented Generation), supervised fine-tuning, and prompt engineering ensures relevance, accuracy, reduced hallucinations, and efficient use of sensitive data.
3. Continuous validation of results — Establish success metrics (accuracy, recall, F1, latency, NPS, conversion), monitor drift in real time, conduct systematic A/B testing, and have humans in the loop for critical cases. Without this, AI degrades silently.

When the 3 pillars work together, GenAI becomes recipe productnot a lab rat.

GenAI use cases that are already delivering ROI in the financial sector.

It's not theory: they exist. Real-world cases running in production. in the Brazilian and global financial sector, with measurable ROI in 90-180 days. Some of the most mature examples:

• Credit analysis and decision Generative models analyze client documents (pay stubs, statements, contracts) in seconds, cross-reference them with credit bureaus and internal records, and suggest approval/denial with traceable justification. Reduces analysis time from 5 days to 15 minutes.
• Fraud detection and anti-money laundering (AML/CFT) GenAI identifies anomalous patterns in transactions, analyzes the context of suspicious operations, generates automatic reports for COAF (Brazilian Financial Intelligence Unit), and reduces false positives by 60-70%.
• 24/7 Customer Service with AI — Generative assistants resolve 60-80% of level 1 requests (balance, statement, duplicate copy, Pix, loan) in natural language, with intelligent escalation to a human only in complex cases.
• Compliance and regulatory reporting — Automatic generation of reports for BACEN, CVM, Susep, IFRS, with source citation, versioning, and audit trail. Reduces compliance team time by 70%.
• Intelligent digital onboarding Automated KYC with OCR + document analysis + biometrics + GenAI validating consistency. Reduces registration fraud and account activation time.
• Summarization and mining of legal documents. — Analysis of contracts, powers of attorney, deeds, and legal proceedings, identifying critical clauses, risks, and opportunities in minutes (not days).

Each of these cases has clear ROI metricsReduced operational costs, reduced fraud, increased conversion rates, faster turnaround times, and customer satisfaction.

Flexa Cloud's experience in financial GenAI.

Flexa Cloud combines technical expertise in GenAI With AWS's global infrastructure and managed services, we help financial institutions move from the pilot phase to production with confidence. Our deliverables are already implemented with:

• data governance and AI Aligned with the LGPD (Brazilian General Data Protection Law), BACEN Resolution 4.658, CVM (Brazilian Securities and Exchange Commission), Susep (Brazilian Superintendence of Private Insurance), and IFRS — featuring a model card, data lineage, paper-based access control, auditability, and model explainability.
• Native and managed AWS stack Bedrock (foundational models), SageMaker (training and MLOps), QuickSight (agentic BI in natural language), IAM, KMS, GuardDuty, Macie — all with on-demand scalabilityCosts controlled via FinOps and consistent performance.
• Results-oriented methodology With discovery, controlled Proof of Concept (PoC), MVP in production within 90 days, scaling with governance. Each phase has objective acceptance criteria, business metrics, and compliance gates.
• AWS Advanced Partner Team With certifications in AI/ML, security, FinOps, and GenAI — with real-world case studies in banks, fintechs, insurance companies, and asset managers in Brazil.
