Advanced Financial Search Engine for RAG Hybrid search combining keywords and semantics, processing 2 million documents across an Elastic Index of 500GB.

Hybrid Financial Search Infrastructure

Enhanced BM25 algorithm for keywords combines with vector-based semantic search in Elasticsearch. Cross-encoder reranking ensures optimal result relevance for complex financial queries.

Keyword Search
Implements BM25 for exact term frequency-inverse document frequency (TF-IDF) scoring.
Semantic Search
Context-aware matching for complex financial relationships
Reranking Search Results
Applies cross-encoder reranking using fine-tuned transformer models, optimizing result relevance and context preservation through sequence-level pairwise scoring

LLM Agnostic Infrastructure Dynamic routing across multiple LLMs optimizes for performance, cost, and latency across different types of financial queries.

Zero Hallucination, Grounded in Source Documents Multi-agent verification system with adversarial checks ensures every response is backed by source documents with consensus validation.

Multi-Agent Verification System

query: What was Apple's R&D spending in 2023?

agent_1 [retriever]: Located source document Apple Inc. 10-K (2023), Page 27
agent_2 [validator]: Verified amount $29.9B matches source text
agent_3 [fact_checker]: Confirmed fiscal year and amount consistency

consensus_response: Apple's R&D spending was $29.915 billion in fiscal year 2023, a 14% increase from $26.251 billion in 2022.

Privacy by Default Enterprise-grade data security and privacy principles built into every layer of our infrastructure.

Principles for data security & privacy

1Data isolation

Private docs are isolated between organizations. We don't mingle them in the same Postgres table or Elastic index. This offers guarantees that a user from firm A will never see data from firm B.

2Control

The org admin can change the configuration of the connector at any time. When that happens, we do a full sync to make sure Fintool only sees what we're explicitly allowed to see.

3Access control

Each document, each data chunk is stored with its up-to-date access rights. Whenever we query a Postgres table or Elastic index, the user must provide his identity with the connector. In essence, if you can't access a document within your org's sharepoint, Fintool AI won't see it.

How we enforce these principles

1Organization Administrator Control

Each org has a single admin — the admin is the person that sets up the connectors

Data model — connectors table with
  • id
  • datasource: str — e.g. sharepoint
  • admin_sub: str — e.g. 66d8fy7gvaf53e2c0aea7512e
  • paths: List[str] — the absolute paths that Fintool can access
  • auth: Dict — the auth information we need to create the connector — connector specific (e.g. tenant-id, …)

2Data Pipeline Artifacts

The data pipeline creates isolated storage artifacts for each organization

Document-level and chunk-level storage with built-in permission controls
  • Isolated data stores per organization
  • Full document metadata for traceability
  • User and group permission enforcement
  • Quantized embeddings for efficient search
