🚀 VentureWise — Smart Crowdfunding Platform for Startups & Investors

VentureWise is an intelligent crowdfunding platform that bridges the gap between promising startups and forward-thinking investors. It leverages data-driven risk assessment, machine learning-based growth forecasting, and an intuitive investment workflow to streamline funding decisions.

📌 Key Features

🧠 AI-Powered Startup Risk Assessment

• Uses KMeans clustering to group startups into Low, Medium, and High risk based on key attributes (revenue, team size, funding history, etc.).
• Assigns a “Risk Label” to help investors evaluate investment feasibility.

📈 5-Year Growth Prediction Model

• Predicts revenue, valuation, and market share over 5 years using a Random Forest Regressor.
• Simulates future performance based on current growth rates, market size, and founder metrics.
• Visualizes growth curves through matplotlib.

💼 Investor Investment Flow

• Investors can view individual startup pages.
• Investment form at /app/investor/startup/[id]/invest allows seamless interaction.
• Smart validation logic for investment amounts and transaction hash given of every investment made.

🔐 Authentication

• Passwordless login using MetaMask wallet (browser extension).
• Users authenticate by signing a message with their Ethereum wallet, ensuring secure, decentralized access.
• Role-based access control (Investor vs Startup) is implemented after wallet verification.

🧪 Tech Stack

• Frontend: Next.js, TailwindCSS, ShadCN UI
• Backend: Express.js, MongoDB
• AI Integration: Flask (via Render.com hosted APIs)
• Auth: MetaMask Wallet (passwordless login), Role-based access Check out Metamask here

🧪 ML Models Used

1. Clustering Risk Model (Unsupervised)

• Preprocessing: Label Encoding + Standard Scaling
• Clustering: KMeans (n=3)
• Output: Cluster label → Risk label (Low, Moderate, High)

2. Growth Prediction Models (Supervised)

• Targets: Revenue, Valuation, Market Share (5 years)
• Model: RandomForestRegressor
• Input Features: Industry, Market Size, Team Size, Revenue, Growth Rate, etc.
