Managing cash flow during a seed round can be daunting, but it is not impossible. Equity financing, while providing capital, can also dilute your control and future returns. To optimize your cash flow and extend your runway, you can seek alternative sources of funding such as debt financing, grants, or crowdfunding. Debt financing can be useful for short-term needs or bridging gaps, but it comes with risks and liabilities. Grants are funds that you receive from a government, foundation, or organization and don't have to repay. They can be helpful for social or environmental causes but can also be competitive and restrictive. Crowdfunding is when you raise money from a large number of people online and offer them rewards or equity in return; it can be a great way to validate your idea but also time-consuming and challenging. You can use tools like Lendio, Kabbage, Fundbox, GrantWatch, Foundation Directory, GrantSpace, Kickstarter, Indiegogo, or SeedInvest to compare and access different options for debt financing, grants, or crowdfunding campaigns.
