Introduction

Startup funding is a crucial part of building and scaling a new business. From the initial idea stage to becoming a market leader, startups require financial backing at different stages of growth. Investors, including angel investors, venture capitalists, private equity firms, and public markets, provide capital in exchange for equity or future returns.

Understanding the different types of funding rounds is essential for entrepreneurs seeking investment and for investors looking to fund promising startups. In this guide, we will break down each stage of startup funding, the key players involved, and the purpose of each funding round.
