The Key Players
Understanding the roles of different individuals and groups in the funding journey of a startup.
You (Founder)
Starts the company with an idea. Initially owns 100% of nothing, which is a lot less than 17% of a big company.
Co-Founder
Joins the founder early on to help build the company. Typically does half the work and receives a significant equity stake.
Friends and Family
Invests before anyone else, often at the lowest price and highest risk. This early support is crucial for getting the idea off the ground.
Angel Investors
Wealthy individuals who invest their own money. Usually an accredited investor with significant business experience.
Venture Capitalists (VCs)
Firms that invest other people's money into promising startups. They typically invest large sums in exchange for significant equity and a board seat.
Early Employees
Join the company post-seed funding. Gamble on the company's success by accepting lower salaries in exchange for stock from the option pool.
Investment Bankers
Manage the Initial Public Offering (IPO) process, handling paperwork and selling the company's stock to the public market, taking a fee for their services.
Anyone (The Public)
After a company goes public (IPO), anyone can buy its shares on the stock market, becoming an investor and partial owner.
