Startups have several funding sources available, each with their own advantages and disadvantages. Bootstrapping, for example, gives you full control and ownership, but limits your growth potential and exposes you to financial risks. Grants, on the other hand, can be a great way to validate your idea and get some traction, but they are often competitive, restrictive, and time-consuming to apply for. Crowdfunding is a powerful way to build a community, generate buzz, and test your market fit; however, it requires a lot of marketing, planning, and fulfillment. Angel investors offer valuable mentorship, connections, and feedback in exchange for equity or convertible notes; however, they also expect high returns and involvement in decision-making. Lastly, venture capital firms can provide large amounts of capital, expertise, and access to networks; yet they demand high growth rates, milestones, and board seats in return.
