You can finance a startup business through four main channels: your own money, equity sold to investors, debt from banks or SBA-backed lenders, and grants or crowdfunding. Each one trades something different. Equity costs you ownership. Debt costs you fixed payments regardless of how the business performs. Grants cost you time and compliance work. Self-funding costs you personal risk. Most founders use several of these in sequence, starting cheap and non-dilutive before moving to larger, more complex rounds.
What follows is how each option actually works, what paperwork and legal rules apply, and where founders most often lose money by moving too fast.
Paperwork Every Funder Will Ask For
Whatever source you approach, the review starts with your financials. The foundation is a business plan with market analysis, operations, and projections. The SBA recommends forecasted income statements, balance sheets, and cash flow statements covering the next five years.1U.S. Small Business Administration. Write Your Business Plan If the business has been operating, include three to five years of actual financials alongside the projections.
SBA loan applicants need SBA Form 1919, the Borrower Information Form covering ownership, criminal history, and any prior government debt defaults, and SBA Form 413, the Personal Financial Statement. Form 413 asks for a full accounting of your net worth: every asset — bank accounts, real estate, vehicles, retirement funds — minus every liability like mortgages, student loans, and credit card balances. Every number should trace to a bank statement, brokerage account, or tax return. Lenders verify what you submit, and discrepancies kill applications fast.
Expect a credit pull on both you and the business. The SBA publishes no hard minimum, but most participating lenders look for personal scores of 680 or higher. A lower score narrows your options and can raise the rate you are offered.
Self-Funding and Friends-and-Family Rounds
Most founders start with their own money. Bootstrapping — personal savings, credit cards, or revenue from early sales — keeps full ownership and avoids outside obligations. The limit is just as plain: your personal finances carry all the risk, and growth is capped at what your own cash supports.
Friends and family rounds sit between bootstrapping and institutional money. Checks are typically small, from a few thousand to a few hundred thousand dollars, written by people who trust you rather than scrutinize your cap table. Treat these investments with the same legal rigor you would apply to an outside investor. Put the terms in writing. Specify whether the money is a loan or an equity stake. Make sure everyone understands they could lose it all. Sloppy documentation here creates tax problems and damaged relationships that no later success fully repairs.
Equity Financing From Angels and Venture Capital
Selling equity means giving up a percentage of the company in exchange for cash with no scheduled repayment. It fits high-growth startups that cannot yet support loan payments.
Angel investors are usually wealthy individuals investing their own money in early-stage companies. Checks often run between $25,000 and $500,000, sometimes with mentorship attached. Venture capital firms pool money from pension funds, endowments, and family offices and write larger checks. A seed round might run from a few hundred thousand to a couple million dollars; a Series A often lands between $2 million and $15 million depending on traction and market size.
Investors will demand a capitalization table — a ledger of every share outstanding, who holds it, the price it was issued at, and any outstanding options or warrants. Every new round dilutes existing shareholders, and if your cap table math is off, sophisticated investors walk away.
Why Your Entity Structure Matters
Most institutional investors require a C-corporation, and many specifically prefer Delaware. The reasons are practical: Delaware’s Court of Chancery handles corporate disputes efficiently, decades of case law make transactions predictable, and the state’s corporate code supports the preferred stock structures venture deals rely on. Delaware also does not collect corporate income tax from companies incorporated there but operating elsewhere. If you are an LLC or S-corp planning to raise institutional equity, expect to convert before closing.
Convertible Notes and SAFEs
Between a friends-and-family round and a priced equity round, many startups use instruments that postpone the valuation question. The two common ones are convertible notes and SAFEs (Simple Agreements for Future Equity).
A convertible note is a short-term loan that converts into equity when a qualifying financing event happens, usually the next priced round. It carries an interest rate and a maturity date, typically 12 to 24 months out. Two features protect the early investor: a valuation cap, which sets a ceiling on the conversion price, and a discount rate, which gives the noteholder a percentage off the price new investors pay. If the note hits maturity without a qualifying round, the investor and company have to negotiate extension, repayment, or a preset conversion.
A SAFE works similarly but is simpler. It is not a loan. There is no interest, no maturity date, and no repayment obligation. The investor hands over cash and receives the right to future equity when a conversion event occurs, typically the next priced round or a sale. SAFEs still use valuation caps and discount rates. Fewer negotiating points and lower legal costs have made SAFEs the default early-stage instrument at many startups.
Debt Financing and Credit Products
If you want to keep full ownership, debt lets you borrow and pay back with interest. The lender has no claim on your equity, but you owe the money whether the business thrives or struggles.
SBA 7(a) Loans
The SBA 7(a) program, governed by 13 CFR Part 120, is built for small businesses that cannot get conventional financing on reasonable terms. Loans go up to $5 million. The SBA guarantees up to 85 percent of loans of $150,000 or less and up to 75 percent of larger loans.2eCFR. 13 CFR Part 120 – Business Loans The guarantee does not eliminate your obligation. You still owe the full amount, but the lender’s reduced risk makes approval possible.
Interest rates on 7(a) loans are capped at the prime rate plus a markup that varies by loan size. For loans over $350,000, the maximum markup is 3 percentage points over prime. For loans of $50,000 or less, it can run up to 6.5 points over prime.2eCFR. 13 CFR Part 120 – Business Loans With the prime rate at 6.75 percent in late 2025, that translated to roughly 9.75 percent on large loans and up to 13.25 percent on the smallest.3FRED. Bank Prime Loan Rate Changes: Historical Dates of Changes Terms extend up to 10 years for most purposes, or up to 25 years when the funds finance real estate.4U.S. Small Business Administration. Terms, Conditions, and Eligibility
Most 7(a) loans require collateral — equipment, inventory, or real estate — plus a personal guarantee from any owner holding 20 percent or more. The SBA charges an upfront guarantee fee that scales with loan amount and term. Review typically runs 30 to 90 days, with back-and-forth as lenders ask for tax transcripts and updated financials.
Microloans
For smaller needs, the SBA Microloan program lends up to $50,000 through nonprofit intermediary lenders. The money can go toward working capital, supplies, equipment, and inventory.5U.S. Small Business Administration. Microloans Terms tend to be shorter, and intermediaries may require business training or technical assistance alongside the loan.
Lines of Credit and Business Credit Cards
A business line of credit gives you a pool of funds you can draw from as needed, paying interest only on the amount in use. That fits uneven cash flow well: covering payroll during a slow month, then paying down when revenue returns. Business credit cards fill a similar short-term role and help build a business credit history when paid consistently.
Both carry fees that add up. Origination fees on lines of credit can run 0.5 to 3 percent of the facility. Credit cards charge higher rates than most term loans, and missed payments hit both your business and personal credit.
UCC Liens on Your Assets
When a lender extends secured credit, they typically file a UCC-1 financing statement with your state’s Secretary of State. That creates a public record of their claim on your collateral, which can include equipment, accounts receivable, or inventory. The filing sets priority: whoever files first has first claim if you default. A blanket lien covers essentially everything the business owns, which complicates future borrowing because any later lender’s claim would sit behind it. Read any secured loan carefully to know exactly what you are pledging.
Grants and Crowdfunding
These sources do not require repayment or ownership dilution, but each comes with its own strings.
SBIR and STTR Grants
The Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs channel federal research dollars to small businesses working on scientific or technological problems.6eCFR. 13 CFR Part 121 Subpart A – Size and Eligibility Requirements for the SBIR and STTR Programs Phase I funds feasibility and proof-of-concept work; Phase II supports expanded research and development. After inflation adjustments, Phase I awards now reach roughly $300,000 and Phase II awards can exceed $2 million, though individual agencies set their own typical ceilings and many awards come in well below. These grants are competitive, and the application reads more like a research proposal than a business plan.
Regulation Crowdfunding
Regulation Crowdfunding under the JOBS Act lets a company raise up to $5 million from the general public in a 12-month period, offering equity, debt, or revenue-sharing agreements through an SEC-registered funding portal. You file Form C with the SEC, disclosing financials, operations, and offering terms.7U.S. Securities and Exchange Commission. Regulation Crowdfunding
Financial disclosure scales with the raise. For offerings of $124,000 or less, financials certified by your principal executive officer are enough.8U.S. Securities and Exchange Commission. Regulation Crowdfunding: Guidance for Issuers Larger raises require review by an independent accountant, and repeat issuers above the higher threshold must provide audited financials.9U.S. Securities and Exchange Commission. Regulation Crowdfunding: A Small Entity Compliance Guide for Issuers Independent audits can cost $10,000 to $30,000 or more for an early-stage company, so factor that in when deciding how much to raise.
Reward-based crowdfunding on platforms like Kickstarter is a different animal. Backers receive a product or perk, not a financial stake. These campaigns are not securities offerings and need no SEC filings, but they also leave you without an investor base for future rounds.
Securities Law Rules You Cannot Skip
Any time you sell equity — to an angel, through a crowdfunding portal, or via a convertible instrument — you are selling a security, and federal and state securities laws apply. Getting this wrong invites lawsuits and SEC enforcement that can end a company before it starts.
Regulation D Exemptions
Most startup equity raises use Regulation D, which exempts certain private offerings from full SEC registration. The two common pathways are Rule 506(b) and Rule 506(c). Under Rule 506(b), you cannot advertise publicly, but you can sell to unlimited accredited investors and up to 35 non-accredited investors with sufficient financial sophistication. You need a reasonable belief each accredited investor qualifies. Under Rule 506(c), you can advertise openly, but every investor must be accredited and you must take reasonable steps to verify their status, a higher bar than reasonable belief.10U.S. Securities and Exchange Commission. Assessing Accredited Investors Under Regulation D
Who Qualifies as an Accredited Investor
An accredited investor is an individual with annual income of at least $200,000 (or $300,000 jointly with a spouse) in each of the past two years, with a reasonable expectation of hitting the same level this year, or net worth over $1 million excluding the primary residence.11U.S. Securities and Exchange Commission. Accredited Investor Net Worth Standard Certain licensed professionals and entities like investment funds also qualify. These thresholds have not been adjusted for inflation since they were set, so the group captured is now much broader than originally intended.
State Blue Sky Laws
Federal exemptions do not fully preempt state regulation. Every state has its own securities laws, commonly called blue sky laws, that may require notice filings, impose fees, or create separate anti-fraud liability. Securities sold under Rule 506 are generally exempt from state registration, but states still enforce their fraud provisions. If investors are in multiple states, expect to make notice filings and pay fees in each one. An experienced securities attorney is not optional here. This is where founders who try to save on legal costs end up paying far more later.
Tax Moves That Save Founders and Investors Real Money
How your funding is structured carries tax consequences that are easy to miss in the rush to close. Two provisions in particular move large amounts of money.
Section 83(b) Elections for Founder Stock
When founders receive stock that vests over time, the default rule treats each vesting date as a taxable event. You owe ordinary income tax on the difference between what you paid for the shares and their fair market value when they vest. For a growing startup, that value can climb sharply between grant and final vesting, producing a large and unexpected tax bill.
A Section 83(b) election flips the timing. You file a one-page statement with the IRS electing to pay income tax on the stock’s value at the time of grant, when the shares are presumably worth very little. If the company succeeds, the gain from grant-date value to eventual sale price gets taxed at long-term capital gains rates rather than ordinary income rates, cutting the effective rate roughly in half.
The catch is the deadline. You must file within 30 days of receiving the stock, and the IRS grants no extensions.12Office of the Law Revision Counsel. 26 USC 83 – Property Transferred in Connection With Performance of Services Miss by one day and you lose the option for that grant permanently. If the thirtieth day falls on a weekend or federal holiday, the deadline moves to the next business day.13IRS. Revenue Procedure 2012-29 – Election to Include in Gross Income in Year of Transfer The risk is also real: if the shares never vest or the company fails, you have prepaid tax on worthless stock and cannot recover it.
Section 1202 Qualified Small Business Stock
Section 1202 of the Internal Revenue Code gives investors a strong incentive. Hold qualified small business stock (QSBS) for at least five years and you can exclude up to 100 percent of the capital gain from federal taxes on the sale. The company has to be a domestic C-corporation using at least 80 percent of its assets in an active qualified business, and the stock has to come directly from the company, not from a secondary market purchase.
The One Big Beautiful Bill Act, signed in 2025, expanded Section 1202 in two ways for stock issued on or after July 4, 2025. The gross asset ceiling rose from $50 million to $75 million, with inflation adjustments starting after 2026, so more companies qualify. And a phase-in schedule now rewards shorter holding periods: three years qualifies for a 50 percent exclusion, four years for 75 percent, and five or more years still unlocks the full 100 percent. The company cannot operate in excluded industries like financial services, hospitality, or professional services such as law, accounting, and consulting.
What Closing Actually Looks Like
Once you choose a path and prepare documents, the process moves to formal submission and due diligence. Loan applications usually go through a bank’s online portal or by certified mail. Lenders then spend weeks verifying everything, pulling IRS tax transcripts, reviewing collateral, and sometimes visiting the business. SBA reviews commonly run 30 to 90 days depending on loan size and complexity.
Equity rounds turn on the pitch meeting. Expect about 20 minutes to present, followed by pointed questions from the investment committee. Investors evaluate the team as much as the business, so they want to see you understand the market cold and have thought through failure scenarios, not just the upside. A successful pitch leads to a term sheet covering valuation, investment amount, governance rights, and liquidation preferences.
Closing an equity round carries more legal complexity and cost than most first-time founders expect. Legal fees for a Series A can run $75,000 or more per side, and startups commonly cover a portion of the investors’ legal costs as well. On the debt side, budget for origination fees, SBA guarantee fees, and attorney costs for reviewing loan documents. Closing ends with signed contracts — loan agreements and promissory notes for debt, stock purchase agreements and amended corporate documents for equity — and a wire transfer into your business account.
Once the money arrives, so do the obligations. Loan agreements usually require quarterly or annual financial reporting. Equity investors may hold board seats or observer rights and expect regular updates on performance, cash burn, and key metrics. Falling behind on reporting, or going silent, erodes the trust that funds your next round.
