Inspiration

The inspiration for DeelFlow came from an observation: connecting investors with promising startups shouldn't be so hard. I realized that venture capitalists and startups are constantly searching for each other, but the process is incredibly fragmented and inefficient. What if there is one unified platform that could

  • Aggregate startups from trusted sources like LinkedIn, Product Hunt, and CrunchBase.
  • Allow VCs to add interesting startups to watchlists easily.
  • Enable seamless progression from watching the pipeline to meeting scheduling
  • Provide reliable, enriched data so investors can make informed decisions quickly I wanted to build a platform that would make deal sourcing as simple as adding items to a shopping cart, but with the sophistication that VCs need for million-dollar investment decisions. The key insight was using AWS Lambda serverless architecture to handle the complex data aggregation and processing in the background while presenting VCs with a clean, intuitive interface that makes discovering and tracking startups effortless.

What it does

DeelFlow is an AI-powered venture capital deal sourcing platform that transforms how VCs discover, analyze, and manage investment opportunities through intelligent automation. Core Features: Intelligent Startup Discovery: Aggregates startups from trusted sources (LinkedIn, ProductHunt, Crunchbase) AI scoring algorithm (0-100) ranks investment potential Advanced filtering by sector, stage, geography, and funding amount Real-time search with sub-2-second response times

Personal Pipeline Management: Watchlist: Save interesting startups for future review Pipeline Stages: Watching → In Pipeline → Closed/Passed Priority Levels: High, Medium, Low priority classification Personal Notes: Add custom observations and insights

AI Document Intelligence Upload pitch decks, financial models (PDF, Word, Excel up to 15MB) AI-powered analysis using Amazon Bedrock (Claude) Interactive chat interface for document analysis Automatic extraction of key metrics (revenue, growth, team size) Comparative analysis across multiple documents

Personalized Dashboard & Analytics Real-time metrics: total startups, pipeline conversion, success rates LLM-generated insights: AI analyzes your portfolio and provides personalized recommendations Sector distribution and geographic analysis Recent activity feed showing team actions Performance trends and ROI tracking

How we built it

Serverless-First Architecture We architected DeelFlow using AWS Lambda as the core compute service, designing nine specialized functions:

  • Knowledge base writer: Indexes uploaded pitch deck data, startup insights, or market intelligence, and stores processed information into a searchable knowledge base (Opensearch).
  • Analyze lambda: Processes and analyzes pitch deck content using LLMs (Claude 3.5 Haiku) in AWS bedrock, extracts key metrics, market size, team info, financial projections, and provides automated scoring and investment recommendations.
  • Document upload lambda: Generates secure, time-limited URLs for file uploads/downloads and enables direct S3 access without exposing AWS credentials.
  • Delete document lambda: Removes documents from the system and handles cleanup and permission validation
  • Get Document: Retrieves documents (pitch decks, business plans, financial statements), including filtering and search capabilities.
  • Get startups Lambda: Fetches startup data from the database
  • User startups lambda: Manages the relationship between VC users and their tracked/invested startups, handles user-specific startup lists, and investment tracking.
  • Dashboard metrics lambda: Retrieves key performance indicators and analytics for the VC dashboard, returns metrics like portfolio performance, deal flow stats, and investment summaries.
  • Authentication Lambda: Handles user authentication, authorization, manages login/logout, token validation, and access control.

Technology Stack: Frontend (React.js) Modern component-based architecture Tailwind CSS for responsive design AWS Cognito authentication integration

Backend (AWS Serverless) AWS Lambda (Python 3.11): Serverless compute functions Amazon API Gateway: RESTful API endpoints with rate limiting Amazon DynamoDB: High-performance NoSQL database Amazon S3: Encrypted document storage Amazon Bedrock: Claude 3 Haiku for AI insights Amazon OpenSearch: Vector search and document indexing Amazon Cognito: User authentication and session management Amazon EventBridge: Scheduled data updates and triggers

Event-Driven Architecture: User Upload → API Gateway → Lambda → S3 Storage → Document Processing → Bedrock AI → OpenSearch Indexing → Real-time Dashboard → User Insights

Data Sources → Lambda → DynamoDB → Cache Layer → API Gateway → Frontend → User Interface

AI Integration Pipeline: Data Aggregation: Lambda functions pull startup data from external APIs AI Scoring: LLM evaluates investment potential Document Processing: Bedrock Claude analyzes uploaded pitch decks Vector Search: OpenSearch enables semantic similarity search Personalized Insights: LLM generates tailored portfolio recommendations

Challenges we ran into

Lambda Cold Start Optimization Problem: Initial Lambda invocations were causing 3-5 second delays for AI processing Solution: Implemented provisioned concurrency for critical functions and connection pooling

AI Response Consistency Problem: LLM responses varied significantly in format and quality Solution: Developed structured prompting and response validation
