Funding Types Playbook

Core Rule

Match the funding type to your stage, speed, and tolerance for dilution. There is no single best way to fund a startup. The right answer depends on your business model, growth trajectory, and what you're willing to give up.

Funding Types Comparison

Detailed Breakdown

Bootstrapping (Self-Funded)

How it works: You fund the business from savings, side income, or early customer revenue.

• Typical amount: $0–$100K
• Dilution: None
• Pros: Full control. No investor obligations. Forces revenue discipline. No board meetings.
• Cons: Limited runway. Slower growth. Personal financial risk. Can't outspend competitors.
• When to use: You have a business model that can generate revenue quickly. You want full ownership. You're building a lifestyle or capital-efficient business.
• Graduate when: You've validated PMF and need capital to scale faster than revenue allows.

Friends & Family

How it works: People who trust you invest based on the relationship, not a formal diligence process.

• Typical amount: $10K–$150K
• Dilution: 0–10% (often structured as a loan or simple SAFE)
• Pros: Fast. Flexible terms. Based on trust.
• Cons: Relationship risk is real. Unsophisticated investors may have unrealistic expectations. Can create legal issues if not documented.
• When to use: You need a small amount to get to a proof point. You have people willing and able to lose the money.
• Key rule: Always use proper legal documents. Treat it like a real investment. Never take money someone can't afford to lose.

Angel Investors

How it works: High-net-worth individuals invest personal capital, typically in exchange for equity via SAFEs or convertible notes.

• Typical amount: $25K–$500K (individual checks of $5K–$100K)
• Dilution: 5–15%
• Pros: Fast decisions. Bring industry connections and credibility. Less formal than VC.
• Cons: Limited follow-on capital. Varies wildly in quality of advice. Can be hard to manage a large angel syndicate.
• When to use: Pre-seed to seed stage. You want capital plus strategic value from specific individuals.
• Where to find them: AngelList, local angel groups, LinkedIn, founder referrals, accelerator demo days.

SAFE Notes

How it works: A Simple Agreement for Future Equity. Not debt. Converts to equity at the next priced round.

Post-Money SAFE (YC standard, recommended):

• Dilution is known upfront. If you raise $1M on a $10M post-money cap, investors own 10%.
• Easier to manage cap table. Founders know exactly how much they're giving up.
• Use the standard docs from ycombinator.com/documents.

Pre-Money SAFE (older format):

• Dilution depends on how much total you raise before a priced round. More SAFEs = more dilution.
• Harder to model ownership. Can surprise founders at conversion.
• Still used, but post-money is now the standard.

• Typical terms: $5M–$15M valuation cap. Sometimes includes a 15–25% discount. MFN clause for early investors.
• Pros: Fast (1 page). Low legal cost ($0–$2K). No interest, no maturity date. Investor-friendly for early bets.
• Cons: Can stack dilution if you raise multiple SAFEs. No voting rights until conversion. Some institutional investors won't use them.

Convertible Notes

How it works: A loan that converts to equity at the next priced round, usually with a valuation cap and discount.

• Typical amount: $100K–$2M
• Dilution: Defined at conversion (cap + discount)
• Key terms: Interest rate (typically 5–8%), maturity date (18–24 months), valuation cap, discount rate.
• Pros: Well-understood by investors. Creates urgency via maturity date. Interest accrues in favor of investor.
• Cons: It's debt — if you don't raise a priced round by maturity, you owe the money. More legal complexity than a SAFE. Costs $3K–$10K in legal fees.
• When to use: Investor prefers notes over SAFEs. You're raising from a mix of institutional and angel investors. You're comfortable with a maturity deadline.

Priced Rounds (Seed, Series A, Series B+)

How it works: You set a company valuation and sell a specific percentage of equity, typically preferred stock with negotiated rights.

• Seed: $500K–$4M. Institutional seed funds + angels. Pre-money valuations of $5M–$20M.
• Series A: $4M–$15M. Lead VC sets terms. Pre-money valuations of $20M–$80M. Requires repeatable growth.
• Series B+: $15M–$100M+. Growth-stage VCs. Clear path to market leadership.

• Pros: Clean cap table. Clear ownership. Institutional credibility. Larger amounts.
• Cons: Slow (2–4 months). Expensive ($15K–$50K+ in legal). Board obligations. Investor expectations for venture-scale returns.
• When to use: You have strong traction and need significant capital. You want institutional partners and governance.

Revenue-Based Financing (RBF)

How it works: You receive capital and repay a fixed multiple (typically 1.3x–2x) as a percentage of monthly revenue until repaid.

• Typical amount: $50K–$3M
• Dilution: Zero. This is repayment, not equity.
• Typical terms: Repay 1.3x–2x the amount. Monthly payments = 2–8% of revenue. No fixed timeline.
• Providers: Clearco, Pipe, Arc, Lighter Capital, Capchase.
• Pros: No dilution. Fast approval. Payments scale with revenue. No board seats.
• Cons: Reduces cash flow during repayment. More expensive than traditional debt. Requires existing revenue.
• When to use: You have consistent monthly revenue ($10K+ MRR). You need capital for a specific growth initiative (inventory, marketing, hiring). You don't want dilution.

Grants (SBIR, State Programs)

How it works: Government or nonprofit programs award non-dilutive capital, typically for research, innovation, or economic development.

• SBIR/STTR Phase I: ~$275K for 6–12 months of R&D feasibility.
• SBIR/STTR Phase II: ~$1M–$2M for full R&D and commercialization.
• State programs: Vary widely. Missouri examples: Arch Grants ($50K), Missouri Technology Corporation, ITEN.
• Pros: Non-dilutive. Validates your technology. Builds credibility.
• Cons: Slow (3–9 month application cycles). Competitive. Reporting requirements. Restricted use of funds.
• When to use: You're building deep tech, health tech, or research-driven products. You have patience for long timelines. You want to preserve equity.

Venture Debt

How it works: A loan (typically from specialized lenders) taken alongside or after an equity round. Secured against company assets or backed by VC investor relationships.

• Typical amount: $1M–$20M (usually 25–50% of last equity round)
• Dilution: Minimal — typically a small warrant for 0.1–0.5% equity
• Typical terms: 2–4 year term. Interest rate 8–15%. May require revenue or equity milestones.
• Providers: Silicon Valley Bank, Western Technology Investment, Lighter Capital, Trinity Capital.
• Pros: Extends runway without significant dilution. Useful bridge between rounds. Keeps cap table clean.
• Cons: Requires existing VC backing or strong revenue. Must be repaid regardless of outcome. Covenants and reporting requirements.
• When to use: Post-Series A. You need 6–12 months of extra runway. You have strong revenue or a committed VC syndicate.

Which Funding Is Right for You?

Answer these questions honestly:

1. Do you have revenue?

• No revenue → Bootstrapping, F&F, Angels, SAFEs, Grants
• Some revenue ($5K–$50K MRR) → RBF, Angels, Seed round
• Strong revenue ($50K+ MRR) → RBF, Series A, Venture Debt

2. How fast do you need capital?

• This week → Bootstrapping, F&F
• Within 1 month → SAFE, Angels, RBF
• Within 3 months → Priced round, Venture Debt
• Within 6–9 months → Grants

3. How much dilution can you accept?

• Zero → Bootstrapping, Grants, RBF, Venture Debt
• Minimal (5–15%) → Angels, SAFEs
• Significant (15–30%) → Priced rounds

4. What's your growth model?

• Lifestyle / steady growth → Bootstrapping, RBF, Grants
• Venture-scale (10x+ returns possible) → SAFEs, Priced rounds, Venture Debt

5. What stage are you at?

Pre-idea       → Bootstrap
Idea + team    → F&F, Grants, Angels
MVP + users    → SAFE, Angels
PMF + revenue  → Seed round, RBF
Scaling        → Series A, Venture Debt
Market leader  → Series B+, Venture Debt

Common Mistakes

1. Raising too early. You give up too much equity before you have leverage.
2. Raising too much. High valuation sets expectations you may not meet. Down rounds are painful.
3. Raising too little. Running out of money mid-execution is worse than not raising at all.
4. Wrong instrument. Using a priced round when a SAFE would suffice costs time and legal fees.
5. Stacking SAFEs without tracking dilution. Multiple pre-money SAFEs can dilute founders far more than expected.
6. Ignoring non-dilutive options. Grants and RBF exist. Use them.
7. Taking money from wrong investors. Misaligned investors create years of friction. Check references.
