CUSTOMER SUCCESS STORY · FINANCIAL SERVICES

HD Securities expands GenAI from financial knowledge to internal AI assistants on AWS.

Generative AI · Financial RAG · Enterprise AI

AT A GLANCE

The project at a glance.

HD Securities develops securities services and digital investing experiences while applying AI to financial knowledge and employee productivity. TitanBases supported two distinct engagements: a financial GenAI and RAG platform, and AiOffice (HDWork), an internal AI platform developed by FintechAI for HDS.

According to TitanBases, the SOW-defined engagements have been successfully delivered and are in production. The architecture combines protected AWS application and data foundations with Amazon Bedrock for generative AI and Bedrock Knowledge Bases for retrieval-augmented generation.

Solution implemented

  • Financial GenAI and RAG with controlled source documents, Amazon S3, Titan Text Embeddings V2 and OpenSearch Serverless.
  • Amazon Bedrock processing for AiOffice and HDWork, connecting AI agents to internal knowledge and existing AWS applications.
  • Networking, data, access, encryption and observability controls appropriate for financial workloads.

Delivery outcomes

  • Two distinct AI workstreams were successfully delivered, as confirmed by the project owner.
  • Context-aware financial knowledge retrieval and managed model integration on AWS.
  • A foundation for customer-facing AI experiences and internal employee productivity with operations and security controls.

ABOUT HD SECURITIES (HDS)

Digital finance powered by trusted knowledge and AI - for customers and employees.

HD Securities provides brokerage, proprietary trading, investment and financial advisory, custody and underwriting services. The company is developing digital investing and wealth-management experiences supported by technology, data and contextual customer service.

In parallel with investor-facing experiences, HDS uses AI for internal knowledge, drafting, summarization, analysis and workflows. AiOffice (HDWork), developed by FintechAI for HDS, was described in the v1.2 SOW as having more than 50 AI agents in development - not 50 verified production agents.

TITANBASES ENGAGEMENT · TWO DELIVERED WORKSTREAMS

TitanBases collaborated on two distinct technical scopes: HDS financial GenAI and RAG, and AiOffice or HDWork developed by FintechAI. They have separate architectures and responsibilities, so this case study presents them independently rather than merging them into one system.

THE CHALLENGE

Business challenge · Financial knowledge · Enterprise productivity

Scaling AI in financial services takes more than foundation-model access.

HDS needed grounded answers to questions about products, accounts, trading and financial topics using controlled sources. Employees also needed AI-assisted drafting, summarization, knowledge access, data analysis and workflow automation.

Financial RAG required protected knowledge retrieval and a reliable application layer. AiOffice already had application infrastructure on AWS but used Google Vertex AI for model services; the migration workstream required evaluation of Amazon Bedrock integration, model suitability, reliability and governance.

DELIVERY SCOPE · FINANCIAL SERVICES

TitanBases owned infrastructure, model integration, knowledge retrieval, security and validation within the SOWs. HDS and FintechAI retained responsibility for application code and business logic.

ENGINEERING AT SCALE · TWO AI WORKSTREAMS

One financial institution. Two AI journeys. Controlled AWS foundations.

Protected application and data layers connect to retrieval-augmented generation and internal AI workflows, while each engagement retains its own SOW-defined system boundaries.

THE SOLUTION

AWS architecture · Financial RAG · AiOffice

Two specialized AI workloads, implemented on AWS.

For financial GenAI and RAG, application traffic passes through Route 53, AWS WAF and load-balanced private compute. Source knowledge is ingested from Amazon S3, embedded with Titan Text Embeddings V2 and indexed in OpenSearch Serverless. Bedrock Knowledge Bases retrieves context for model-generated responses; PostgreSQL supports application data.

For AiOffice (HDWork), FintechAI develops the internal AI application on AWS. TitanBases supported the Bedrock model-processing and migration workstream. The SOWs differ in their compute descriptions; both source diagrams remain separate and must be checked against the latest as-built state before public disclosure.

DELIVERY SUCCESS · PRODUCTION

Two generative AI engagements, delivered and brought into operation.

TitanBases confirms completion and production status. The following are delivered technical capabilities and workloads - not invented model-accuracy, employee-time-savings or measured-uptime statistics.

FINANCIAL KNOWLEDGE

RAG

Grounded financial-knowledge retrieval that augments context before response generation

GENAI MODEL PLATFORM

Bedrock

Managed foundation-model access integrated with the existing application environment

ENTERPRISE PRODUCTIVITY

HDWork

Document work, internal knowledge and employee-oriented AI workflows

SECURITY · OBSERVABILITY

Secure

Access, encryption, observability and repeatable infrastructure practices

The 99.9% availability and concurrency criteria in the SOWs are design and test targets, not published production measurements. More than 50 AiOffice agents are described as in development, not as verified live agents.

TECHNOLOGIES

An AWS ecosystem for secure applications, data and AI.

Services are combined from two separate SOWs and grouped by their roles. This does not imply that every listed service runs in the same HDS production cluster or environment.

PRODUCTION · NEXT STEPS

From financial retrieval to AI that supports everyday work.

TitanBases confirms both projects were delivered. With HDS approval and current as-built and operational evidence, this story can incorporate response times, RAG quality, productivity improvements and AiOffice rollout scope without changing the Golden Visual.
