What is startup funding?
Startup funding, or startup capital, is the money a new company raises to launch and grow, covering its initial expenses and funding operations until it can generate its own revenue. This money covers everything from building the first version of your product and hiring your initial team to renting office space and marketing. It’s the fuel that turns a great idea into a real business—an engine powered by significant capital, with startup funding in 2024 reaching nearly $314 billion.
While startup capital is necessary for growth, the source and terms of the capital you accept will directly affect your ownership and control over the company you're building. Every dollar you take from an investor comes with expectations and a stake in your company's future.
Understanding this tradeoff is the first step in making smart fundraising decisions. The capital you raise is a tool, and like any tool, how you acquire and use it will determine your success.
What are the types of startup funding?
There are several common ways to secure funding for your startup from different types of investors, including bootstrapping, debt financing, and equity financing. The path you choose will affect your ownership and control over the company. Understanding these options is the first step toward making a strategic decision that aligns with your long-term vision. Each path has different implications for who owns and controls the company.
| Funding type | What it is | Who keeps ownership? |
|---|---|---|
| Bootstrapping | Using your own savings or cash flow from early sales to grow the business | You keep all of it |
| Debt financing | Borrowing money from a bank or lender that you must repay with interest | You keep all of it, but you owe money |
| Equity financing | Selling a piece of your company to investors in exchange for cash | You give a portion to investors |
As Jeff Bussgang, a general partner at Flybridge, explained during Carta’s Pre-Seed Fundraising Q2 2024 webinar, there are many ways to build a great business, and the venture capital (VC) path isn't the only one. Some founders may start their journey thinking they are a venture-backed company, only to realize another path makes more sense. The key is to make the right choices for your business day in and day out.
Bootstrapping, self-funding, and friends and family
Many founders start by using their personal savings or getting money from their immediate network of friends and family. This is often called bootstrapping.
Even if the money comes from a close friend or family member, it’s important to treat these investments with professionalism. You should document every investment from day one. This avoids confusion and prevents serious legal problems down the road.
Debt and alternative financing
Other funding options include debt financing, equity crowdfunding, and small business loans and grants, such as those available through the State Small Business Credit Initiative (SSBCI) and the Small Business Administration (SBA), which has seen dramatic growth in its 7(a) Loan Program’s smallest loans for diverse entrepreneurs.
Venture debt: Venture debt is a bank loan for companies between VC funding rounds, with less associated dilution for shareholders. This is one type of debt financing.
Equity crowdfunding: This is the process of collecting small contributions from a large number of people, typically through online crowdfunding platforms. Some crowdfunding websites specialize in fundraising for businesses and can get the pitch out to a large group of general investors ( unaccredited investors included).
Loans and government grants: Some companies might qualify for public or private small business loans, small business grants, or other business credits with a longer period for repayment.
Equity financing
Equity financing is a type of startup funding where investment firms provide capital to early-stage companies that they believe have high growth potential. In exchange for this money, the investors receive equity, or an ownership stake, in the company. This is the most common path for startups that plan to scale quickly.
What types of investors provide startup funding?
Startup capital can come from virtually anywhere, but these are some of the most common sources of financing:
Angel investors: Angel investors are high-net-worth individuals who invest their own money into early-stage startups. They often provide valuable mentorship and industry connections in addition to capital, acting as strategic partners who can open doors for your company.
VC firms: Venture capitalists provide capital to early-stage companies that they believe have high growth potential. In exchange for this money, the investors receive equity in the company. VCs are looking for companies that can become market leaders.
Institutional investors: Institutional investors are typically large asset managers that pool funds from a variety of different institutional and retail investors to invest in growth-stage or pre-IPO startups, as well as other asset classes like private equity and public market investments. Examples include investment firms like Fidelity and T. Rowe Price.
Accelerators and incubators: Startup accelerators and incubators provide a small amount of funding, mentorship, and resources in exchange for an equity stake in the company.
How do you find the right investors?
Funding your startup is about finding the right investors to be long-term partners, not just taking money from anyone. The best investors bring capital as well as industry expertise, a valuable network, and guidance to help you grow. Your goal is to find someone who believes in your vision and has the experience to help you achieve it.
A walkthrough of the startup funding rounds
Now that we’ve covered the basics, we’re ready to examine the rounds of startup fundraising. Each round of funding has a different purpose and process with its own goals, investor expectations, and impact on your company’s ownership structure. Understanding this journey helps you plan for what's ahead.
Pre-seed and seed funding: Getting your company started
If you’ve identified a market opportunity, just started building a minimum viable product (MVP), or have a prototype of your product, then your company is likely in the pre-seed or seed stage.
Common fundraising mistakes to avoid
The fundraising journey is a learning process for every founder. Being aware of common pitfalls can help you avoid unforced errors and set your company up for success.
- Not understanding dilution: Giving away too much ownership too early can limit your control and future fundraising ability.
- Accepting misaligned capital: Taking money from investors who don't share your vision can lead to conflict.
- Maintaining a messy cap table: An inaccurate cap table can lead to costly legal fees and can delay or even kill a funding round.
