Funding: From Bootstrapping to Venture

Raise money only when you know what it will buy. Every source of capital comes with expectations about how fast you grow, how much of the company you give up and what kind of outcome counts as success. This chapter walks through the options, explains the common instruments in plain terms, and shows how to run a raise without letting it swallow the company.

This is general information, not legal or financial advice. Rules differ by country and change over time, so use a lawyer for any document you sign.

Whether to Raise at All

Start by asking what the money is for. If you can name what it buys, such as a hire, a launch or a year of runway to reach a revenue target, you have a reason. If the honest answer is "to feel like a real company", you do not.

Venture capital suits a narrow kind of business: one that could become very large, in a market that is opening now, where spending ahead of revenue is the only way to win. The reason is arithmetic. Venture returns are dominated by a few outliers; Paul Graham wrote in 2012 that Dropbox and Airbnb alone accounted for about three quarters of the value of all YC-funded companies at the time. Many good companies do not fit that shape, and taking venture money commits you to chasing an outcome your business might not need.

Before you raise, answer these honestly:

• Can this business plausibly become large enough for the investor's model to work?
• Would more money now make you meaningfully faster, or just more comfortable?
• Are you willing to give up some control and accept pressure toward a big exit?

Bootstrapping and Other Options

Bootstrapping means funding the company from your own savings and, as soon as possible, from customer revenue. You keep ownership and control, and the need to earn money disciplines every decision. The cost is speed: you grow only as fast as revenue allows, and you may carry personal financial risk.

Revenue-funded growth works especially well for software that is cheap to serve, for services that turn into products, and for businesses whose customers will pay upfront. Many founders bootstrap until they have proof and then raise on better terms; some never raise at all. Bootstrapping does not cap the outcome. Mailchimp, founded in Atlanta in 2001, grew without venture funding from outside investors and agreed in 2021 to be acquired by Intuit for about $12 billion.

Each other source of capital expects something different in return:

• Grants from governments, foundations and research bodies provide non-dilutive money, meaning you give up no equity. In the US, the SBIR and STTR programs, branded America's Seed Fund, award non-dilutive funding through 11 federal agencies. Check their status before you plan around them: after a lapse of about six months, Congress reauthorized both programs in April 2026, through September 30, 2031. Expect applications, reporting and restrictions on how the money is spent.
• Angel investors are individuals investing their own money, usually early. They want equity and a chance at a large return, and good ones bring advice and introductions. In the US, many of the exemptions used for private rounds limit participation to accredited investors; for individuals the SEC's tests include net worth over $1 million excluding the primary residence, or income over $200,000 ($300,000 with a spouse or partner) in each of the last two years.
• Accelerators typically offer a small investment, a structured program and a network in exchange for equity. Terms vary widely. Y Combinator's published standard deal, for example, is $500,000: $125,000 for 7% on a post-money SAFE, plus $375,000 on an uncapped SAFE. Most of the value lies in the program, the peers and the access, so compare those carefully.
• Venture studios co-build companies with founders, providing team, product and go-to-market help in exchange for equity, fees or both. Studios such as AW3 can get a product to market quickly, but read the terms closely and understand what you will own afterward.
• Seed and venture capital funds invest other people's money and need a few companies to return the whole fund. They expect ambitious growth and regular reporting, and often take a board seat in later rounds.

SAFEs, Notes and Dilution

Early rounds are often done with instruments that put off pricing the company until a later, larger round.

The SAFE (Simple Agreement for Future Equity) was created at Y Combinator in 2013, and YC standardized on the post-money SAFE in 2018. A SAFE is not debt: it carries no interest and has no maturity date. The investor gives you money now and receives shares later, usually when you raise a priced round. It typically carries a valuation cap, a discount or both, which limit the price at which the investor's money converts. With the post-money version, the ownership sold is easy to calculate: roughly the investment divided by the post-money valuation cap.

SAFEs now dominate the earliest rounds. SaaStr's summary of recent Carta data reports 92% of pre-seed rounds now using SAFEs, up from 54% in 2019, with the post-money, cap-only SAFE the most common form.

A convertible note serves a similar purpose but is legally debt. It carries an interest rate and a maturity date, and usually converts into shares at the next priced round, often with a cap or discount. Traditionally the principal and interest fall due at maturity, though in early-stage notes investors often get to choose between repayment and conversion. Understand that term before signing.

Dilution is the reduction in your percentage ownership when the company issues new shares. Here is a simple example. The numbers are hypothetical and leave out details such as option pools and discounts.

• You and your co-founder own 100% of the company.
• You raise $1 million on a post-money SAFE with a $10 million cap. The SAFE investor will own 10%, leaving founders at 90%.
• Later you raise a priced seed round: $3 million at a $12 million pre-money valuation, so $15 million post-money. The new investors own 20%.
• Everyone else is diluted by that 20%. Founders go from 90% to 72%, and the SAFE investor from 10% to 8%.

Owning a smaller share of a more valuable company can be a good trade. The danger lies in stacking SAFEs without tracking what they add up to, then discovering at the priced round that you own far less than you thought. The same Carta data put median founding-team ownership at 56.2% after a priced seed round and 36.1% by Series A. Model every raise in a spreadsheet before you sign.

What Investors Look For

Early investors are judging with limited data, so they look for a few signals:

• A team that can execute, with a clear reason why you are the right people for this problem.
• Evidence of demand: ideally revenue, usage growth or strong retention, and at minimum customers who can describe their pain in their own words.
• A large or fast-growing market, explained simply and specifically.
• A sharp story about why now, what you know that others miss, and how you will win.

Traction does most of the persuading. Pitch decks matter less than founders expect. A short deck that explains the problem, the product, the evidence and the plan is enough.

Running a Tight Process

A drawn-out raise can eat months. In "How to Raise Money", Paul Graham argues that the hours are not the main cost: fundraising becomes the top idea in your mind, and growth slows. A tight process builds momentum and protects your time.

1. Prepare first: deck, financial model, cap table, data room and a target amount with a clear use of funds.
2. Build a list of investors who actually invest at your stage and in your area. Warm introductions from founders they backed work best.
3. Schedule first meetings close together over a few weeks, so interest builds in parallel rather than one investor at a time.
4. Follow up quickly, answer questions in writing and keep a simple tracker of every conversation.
5. Once someone commits, set a close date and push the others toward a decision.

Keep running the company throughout. Investors notice when metrics stall during a raise, and a growing business is your strongest argument.

Clean Cap Table and Data Room

Your cap table records who owns what: founders, employees, investors and every SAFE, note and option. Keep it accurate from day one, ideally in a dedicated tool rather than an ad-hoc spreadsheet. Messy ownership records slow down every future round and can delay or derail an acquisition.

A data room is a shared folder that lets investors check your claims. A sensible early one includes:

• Incorporation documents and any board or shareholder approvals
• The cap table and copies of all SAFEs, notes and equity grants
• Founder agreements, including vesting and intellectual property assignment
• Key customer contracts and a summary of revenue
• A financial model and recent financial statements

Build it before you need it. Diligence then moves quickly, and investors see a company that keeps its records in order.
