Different types of dilution scenarios can affect your ownership stake and valuation, depending on the stage and nature of the financing round. For example, a seed round is the earliest stage of financing, where the company raises capital from angel investors, friends, and family, or crowdfunding platforms. The dilution is usually high due to the company's low valuation; however, this also means that the potential upside is high as the company can grow rapidly and increase its valuation in future rounds. Later stages of financing, like Series A, B, C, etc., involve raising capital from venture capitalists, private equity firms, or corporate investors. The dilution is usually lower here as the company has a higher valuation and can negotiate better terms with investors. Additionally, an option pool is a percentage of shares that the company reserves for its employees, advisors, and board members as an incentive to join and stay with the company. This option pool is usually created before each financing round and causes existing shareholders to be diluted by its amount. Finally, convertible notes are debt instruments that can be converted into equity at a later date with a discount or cap. They are often used by startups to raise capital quickly and cheaply without having to negotiate a valuation; however, they also can cause dilution when converted into equity based on conversion terms and the company's valuation at that time.
