If you’re starting a business, you’re going to need money. And depending on what type of business you’re starting you might need a little to get off the ground, or you might need a lot. I’ve started businesses with $50k and I’ve launched businesses that cost eight figures of investment to get to break-even.
Startup funding is money used to launch and grow a business. It can come from your savings, customers, investors, or lenders. Each source comes with a different cost: your cash, a share of ownership, or a promise to repay.
Start with what the money needs to do. Testing an idea with no sales is different from buying inventory that customers already want. The funding should fit that risk and the time it takes to get paid.
Startup funding: equity vs. debt
Equity financing means selling a share of your business. Investors get part of the future value. You generally have no scheduled loan payments, but you own less of the company. Investors may also get board seats or the right to approve major decisions.
Debt financing means borrowing money that you must repay under a contract. Most loans do not give the lender ownership. They do give the lender rights, which may include claims on business assets and limits on how you run the business.
The main trade-off is simple: equity shares the upside and risk. Debt preserves more ownership but adds a bill the business must cover.
| Question | Equity | Debt |
|---|---|---|
| Do you give up ownership? | Yes | Usually no; some loans include warrants |
| Must you repay the funding? | Usually no scheduled repayment | Yes, under the contract |
| What does it cost? | A share of future value and possible control rights | Interest, fees, and sometimes equity rights |
| What if sales fall? | No loan bill, but investors can lose money | Payments may still be due; default puts assets at risk |
| Who controls decisions? | Investors may get votes or approval rights | Loan rules can limit spending or borrowing |
| When can it fit? | Uncertain growth with a large potential payoff | A credible repayment plan supported by cash flow, assets, or investor backing |
A warrant gives a lender the right to buy equity at an agreed price. A personal guarantee makes an owner responsible for repayment if the business cannot pay. Keeping your shares does not mean keeping all the risk inside the company.
Where founders get funding
1. Your savings and customer revenue
Bootstrapping means using your own resources and the cash the business earns. You avoid selling shares to outside investors and can choose your own pace.
The limit is what you can afford to lose. Set a personal cash limit before you start. A business that drains the household savings can become a family problem long before it becomes a funding story.
Customer deposits, paid pilots, and annual prepayments can also fund growth. But that money comes with work attached. Budget for delivery, support, and any refunds you may owe.
2. Friends and family
People who know you may provide a loan or invest in the business. Put the terms in writing: what they receive, whether repayment is required, and what happens if the company fails.
Do not treat every family check as a SAFE. The right agreement depends on the business and the deal. The SEC explains that friends-and-family investments do not have their own special exemption from securities rules.
3. Angel investors
Angels invest their own money. They may back a founder before a larger fund will and can bring advice, contacts, or industry knowledge.
They can buy equity or use an agreement that converts into equity later. Check sizes and terms vary. Look for investors who understand your business and agree on what success should look like.
4. Accelerators
Accelerators offer a set program of mentoring, introductions, and help building the company. Some invest money in exchange for equity or a SAFE. Others do not take ownership.
Compare the full deal, including every investment agreement. Ask past founders whether the program helped them win customers, hire, or raise money. A well-known name alone does not tell you what the program is worth.
5. Venture capital
Venture capital firms invest money managed on behalf of their investors. They seek companies that can grow enough to produce a large return, usually through a sale or public offering.
That can suit a business with a large market and a product that can reach many customers. It may clash with a founder who wants a steady income, slower growth, or no plan to sell.
Pre-seed and seed describe early rounds. Series A, B, and later rounds usually follow as the company develops. These labels do not set a required funding amount or ownership percentage.
You do not need to follow that sequence. Raise for a clear milestone, such as proving demand or reaching a repeatable sales process, rather than chasing the next round’s label.
6. Loans and credit lines
Debt works best when you can explain how and when the lender gets paid. The main options include:
- Bank loans and credit lines. A term loan funds a defined expense over time. A credit line lets you borrow, repay, and borrow again within its terms. Banks assess cash flow, credit, assets, and operating history. See our small business loans guide.
- SBA-backed loans. The SBA 7(a) program supports loans up to $5 million. The SBA guarantees part of the lender’s risk; it does not erase your debt. Eligible startups may qualify, but lenders still need a sound repayment case. SBA microloans, made through nonprofit intermediaries, can provide up to $50,000 to start or expand a business. Our SBA loan guide covers the options.
- Equipment and invoice financing. Equipment can support a loan secured by that asset. Businesses with unpaid customer invoices may borrow against them or sell them to a factoring company. Fees, customer quality, and who bears nonpayment risk matter.
- Business credit cards. Cards can cover small, short-term expenses. Carrying a balance can be costly, and many small-business cards require a personal guarantee.
Revenue alone does not prove you can afford debt. Check your contribution margin, overhead, cash collection timing, and existing payments.
7. Venture debt
Venture debt is designed for venture-backed companies, including some that are not profitable. Lenders consider the business, its investors, cash runway, and ability to raise more capital.
It can extend the time between equity rounds. But interest, fees, principal payments, and warrants reduce that benefit. Silicon Valley Bank’s venture debt overview explains how this differs from ordinary cash-flow lending.
Do not treat another equity round as guaranteed repayment money. Model what happens if that round arrives late or never happens.
8. Revenue-based financing
In a revenue-share structure, a provider supplies capital and collects a percentage of revenue until an agreed amount has been repaid. Payments can move with sales. Lighter Capital describes this model for businesses with recurring revenue.
Products sold under this label differ. Some have fixed payments, minimum payments, or deadlines. Some are loans; others are structured as purchases of future receivables.
Compare the actual contract. Check the total repayment, payment frequency, liens, guarantees, and annualized cost. A 10% flat fee is not the same as a 10% annual interest rate.
9. Crowdfunding
Reward crowdfunding raises money from supporters who expect a product or other reward. It can test demand, but manufacturing, shipping, and refunds still need a budget.
Investment crowdfunding sells securities, such as equity or convertible instruments. In the U.S., Regulation Crowdfunding allows eligible companies to raise up to $5 million in 12 months through a registered broker-dealer or funding portal. Disclosure and reporting rules apply.
10. Grants and other support
Grants can help fund qualifying research, exports, or local development projects without selling ownership. They have rules about who qualifies and how the money can be spent.
Do not assume a general grant will pay to launch your company. The SBA states that it does not provide grants to start or expand a business. Its grant programs serve specific purposes.
Tax credits may also reduce eligible costs, but they are not the same as cash received at a funding close. Confirm eligibility and timing before counting them in your budget.
How SAFEs and convertible notes work
A SAFE, short for Simple Agreement for Future Equity, gives an investor rights to future equity under its terms. A standard Y Combinator SAFE is not a loan: it has no interest or maturity date. It usually converts when the company raises a priced equity round and also addresses a sale or shutdown.
A convertible note is debt. It generally earns interest, has a maturity date, and can convert into shares if the agreed conditions occur. Read what happens if no qualifying round takes place.
Either instrument may use a valuation cap, a discount, or other terms that affect the investor’s share price. The paperwork may delay a priced round, but it does not remove dilution. Model the ownership impact before accepting the money.
What dilution looks like in dollars and shares
Suppose your founding team owns 100% of the company. You raise $1 million at a $4 million pre-money valuation. The post-money value is $5 million, so the new investor owns 20% and the team owns 80%.
If the next round sells another 20% of the company to new investors, the team’s share falls to 64%: 80% × 80%.
This simple example excludes employee option pools, SAFEs, notes, and warrants. Those can reduce ownership further. It is an illustration, not a market benchmark.
A smaller stake can still be worth more if the funding builds a more valuable company. But ownership percentage is only part of the deal. Investor preferences can affect who gets paid first when the business sells.
How to choose the right funding
Before you approach anyone, answer these four questions:
- What will the money buy? Name the expense and the milestone. Reordering proven inventory is different from spending two years developing a product.
- When does the money come back? Build a monthly cash forecast. For debt, include all payments and a slower-sales case. A future funding round is a possibility, not cash in the bank.
- What can you afford to give up? Compare ownership, approval rights, fees, collateral, and personal guarantees. The cheapest headline offer may carry the hardest terms.
- What business do you want to own? A company built for a large exit has different funding needs from one built to pay its owners a steady income.
For an unproven idea, start with a small test funded by savings, customers, grants you qualify for, or investors willing to take the risk. For a proven business with a clear cash cycle, compare debt with the cost of selling more equity.
Use enough capital to reach the next useful milestone, with room for delays. Funding should help the business work, not become the thing the business exists to chase.
