Summary

Financial analysts and investment professionals spend significant time manually analyzing filings, market data, and company reports.
We developed an AI assistant that is capable of ingesting large volumes of financial documents, understanding context, and generating investor-grade insights to automate this workflow.
The assistant mimics a junior analyst: answering questions, summarizing documents, extracting metrics, and surfacing risks, thereby speeding up decision-making.
Our custom solution combines LLMs, real-time RAG pipelines, and secure document ingestion to support professionals across private equity, venture capital, and corporate finance.

Tech Challenge

Accuracy and Verifiability. Financial data must be trustworthy and traceable back to original sources.
Latency at Scale. Queries must return within seconds, even as the document database grows.
Unstructured Complexity. Relevant data is buried across diverse formats: scanned PDFs, Excel models, and regulatory filings.
Financial Fluency. The assistant must speak the language of finance and understand domain-specific workflows.
Multi-Tier Reasoning. Some tasks require simple entity extraction, while others involve deep reasoning or synthesis.

Solution

Deployed a real-time RAG pipeline using Milvus for storing vector embeddings of financial documents such as SEC filings, investor reports, CIMs, and earnings call transcripts.
Implemented a multi-model architecture where different LLMs are used based on task complexity—fast models for basic tasks, and advanced models like GPT-4o or Claude Opus for deeper financial analysis.
Developed a dynamic orchestration layer to intelligently route user queries to the most suitable LLM, based on intent detection and query complexity scoring.
Enabled secure ingestion and parsing of financial documents using OCR, PDF extractors, and Excel parsers, allowing users to upload confidential information and receive structured summaries or metrics.
Created a chat-based user interface for financial professionals to interact with the assistant, ask natural language questions, and receive structured, sourced answers with citations and highlights from original documents.
Incorporated fine-tuned models for specific financial tasks like EBITDA detection, risk factor extraction, or clause recognition in legal contracts, ensuring precision in domain-specific outputs.
Guaranteed auditability and trust by linking each generated output to the exact source location (page, paragraph, or table).

An analyst at a mid-market PE fund uploads a 50-page confidential information memorandum (CIM) and asks: “Summarize the key investment risks and revenue growth assumptions.”

Within seconds, the assistant returns: bullet list of red flags (e.g., customer concentration, upcoming debt maturity), a chart of historical vs projected growth, direct quotes from the original CIM with page references.

The analyst saves 3–5 hours of manual review, and can immediately refine their questions or draft follow-up analyses.

Impact

55% reduction in time-to-insight for preliminary company assessments.
Analysts now spend more time on interpretation and strategy, not data extraction.
Increased deal velocity through faster screening, modeling, and memo generation.
The assistant serves as an institutional knowledge layer, preserving past research and surfacing it on demand.
