## Overview

Investment Spot is an Express/MongoDB web app connecting startup founders and investors. Visitors browse startup and investor listings, educational and school/college sections, and featured stories; founders and investors can register and sign in, with separate dashboard pages. The payment flow uses Razorpay order creation and payment lookup. The graph reflects the README’s broader capabilities, but several route and view implementations were not sampled, so links for those features are limited to documented routing/controller structure.

Main entry points: [`controllers/homeController.js`](https://github.com/himanshusalagre/fintech-open-month-hackathon/blob/main/controllers/homeController.js) (Page controller), [`routes/index.js`](https://github.com/himanshusalagre/fintech-open-month-hackathon/blob/main/routes/index.js) (Application routes), [`index.js`](https://github.com/himanshusalagre/fintech-open-month-hackathon/blob/main/index.js) (Express server), [`config/passport-strategy-local.js`](https://github.com/himanshusalagre/fintech-open-month-hackathon/blob/main/config/passport-strategy-local.js) (Local authentication)
