Bootstrapping: Bootstrapping involves self-funding the startup using personal savings, credit cards, or revenue generated from the business. While bootstrapping requires founders to be financially disciplined and may limit initial growth, it allows them to maintain full control over the company and retain ownership.

Equity Financing: Equity financing involves raising capital by selling ownership stakes (equity) in the company to investors. This can include angel investors, venture capital firms, or corporate investors. In exchange for funding, investors receive equity shares, which may dilute the ownership of the founders. Equity financing is suitable for startups with high growth potential but can be challenging to secure and may require giving up some control over the company.

Convertible Notes: Convertible notes are a form of debt financing commonly used by startups in the early stages. Investors provide funding in the form of a loan that converts into equity at a later date, typically during a subsequent financing round. Convertible notes offer flexibility in valuation and terms, making them attractive to both startups and investors.

SAFE (Simple Agreement for Future Equity): SAFE is a type of financial instrument developed by Y Combinator that allows startups to raise capital without specifying a valuation. Investors provide funding in exchange for the right to receive equity shares in future equity financing rounds. SAFE agreements are relatively simple and flexible, making them popular among early-stage startups.

Revenue-Based Financing: Revenue-based financing involves raising capital by selling a percentage of future revenue to investors. Unlike traditional equity financing, investors receive regular payments based on the startup’s revenue until they achieve a predetermined return on their investment. Revenue-based financing is suitable for startups with steady revenue streams but may be more expensive than equity financing in the long run.

Crowdfunding: Crowdfunding platforms allow startups to raise capital from a large number of individual investors or backers. This can include rewards-based crowdfunding (e.g., Kickstarter, Indiegogo), where backers receive products or perks in exchange for their contributions, or equity crowdfunding, where investors receive equity shares in the company

Grants and Government Funding: Startups can explore grants, subsidies, and government funding programs offered by public agencies, non-profit organizations, or research institutions. These programs provide non-dilutive funding to support specific projects, research, or innovation initiatives.
