The impact of joining a startup accelerator on your company's valuation is multifaceted, starting with equity dilution. Typically, accelerators ask for about 3-10% equity in exchange for their investment and support. So, while you gain access to invaluable resources, mentorship, and potential investor connections, you're also parting with a slice of your company. Equity dilution is a natural part of startup growth, but learning how to manage it is important since it can change both your financial stake in the company and how much control you have.
