What is an angel investor?
An angel investor is an individual (or an entity controlled by an individual) who supplies early-stage capital to a startup in exchange for ownership—typically shares or another form of equity. Unlike a bank loan, angel money is not repaid on a schedule; the investor expects a return only if the business grows and creates value for shareholders.
Brief origin and role
The term came from theater patrons who financed Broadway productions and were paid only if the show succeeded. In startups, angels fill the financing gap that exists before a business attracts institutional venture capital (VC) or can access traditional bank credit. Many angels are former entrepreneurs or professionals with spare capital and an interest in new ideas.
Key definitions (first use)
– Seed money: initial capital used to start or develop a business idea.
– Equity: ownership share in a company.
– Accredited investor: a regulatory classification (set by the U.S. Securities and Exchange Commission) that permits access to certain private investments based on net worth or income.
– Venture capitalist (VC): a professional investor or firm that pools other people’s money to invest, typically at later stages and in larger amounts than angels.
How angel investing typically works
– Source of funds: Angels usually invest their own money. They may invest as individuals or through vehicles such as an LLC, trust, or a small fund.
– Timing and size: Angels provide seed-stage capital. Typical single-investment amounts vary by experience; experienced angels average roughly $42,000 per deal and less-experienced angels about $25,000 (industry figures).
– Structure: Angels generally receive equity and often request governance rights such as a board seat or observer status.
– Return profile and risk: Startups are high risk. Only a small fraction of ventures produce positive outcomes; industry research has found low success rates and that only a minority of individual angel investments are profitable. For those that do succeed, returns can be substantial, but outcomes are skewed.
Typical motivations and involvement
Angels look for novel ideas and founders they trust. Some are passive investors; others provide mentoring, industry contacts, or active help. They are seeking higher-than-market returns in exchange for assuming high risk.
Who becomes an angel
Any individual with sufficient capital and willingness to take high risk can act as an angel. Many choose to qualify as accredited investors to access more private offerings; under SEC guidance, this designation generally requires a net worth or income threshold (for example, a $1 million net-worth benchmark or annual income levels over recent years).
Where angels find deals
Entrepreneurs and angels meet through personal networks, angel groups, demo days, startup accelerators, and online platforms. Angels may participate alone or syndicate with other angels to spread risk.
How angels differ from venture capitalists
– Source of capital: Angels use their own money. VCs manage pooled funds from many limited partners.
– Stage and ticket size: Angels usually invest earlier and
earlier, and in much smaller “ticket” sizes (typical single angel checks range from a few thousand up to $250,000 or more) compared with venture capital funds that write larger Series A and later-stage rounds.
– Involvement and mentorship: Angels often take a hands-on role—advising, opening contacts, helping hire—while many VCs act more as board-level governors and suppliers of ongoing institutional resources.
– Risk and return expectations: Angels accept very high failure rates and long hold periods (5–10+ years). They seek outsized returns on a small number of winners to offset losses.
– Due diligence and process: Individual angels usually do lighter, faster diligence than institutional VCs, who follow formal investment committees and legal processes.
– Control and governance: Angel deals commonly give founders more control early on (fewer governance strings), but terms vary widely and can include protective provisions and board seats.
– Follow-on capacity: Angels use personal capital and may have limited ability to lead large follow-on rounds; many negotiate pro rata rights (the right to invest in later rounds to maintain ownership).
Common deal structures and key terms
– Equity (priced round): Investor buys common or preferred stock at an agreed valuation. Pre‑money valuation = company valuation before the new capital; post‑money = pre‑money + new investment.
– Convertible note: A short-term debt that converts into equity at the next priced round, typically with a discount (e.g., 20%) or valuation cap that favors the noteholder.
– SAFE (simple agreement for future equity): A contract that converts to equity at the next financing under specified terms, without accruing interest like a note.
– Typical term-sheet items to watch:
– Valuation (pre‑ and post‑money)
– Ownership percentage and share class (common vs preferred)
– Liquidation preference (how proceeds are divided on exit)
– Anti-dilution protection (rare in pure angel deals)
– Board composition and protective provisions
– Pro rata (follow-on) rights
– Vesting schedules for founders
– Information rights
Worked example — ownership and dilution (step-by-step)
1) Offer and valuation:
– Company pre‑money valuation: $2,000,000
– Angel investment: $100,000
2) Post‑money valuation = pre‑money + investment = $2,000,000 + $100,000 = $2,100,000
3) Angel ownership % = investment / post‑money = $100,000 / $2,100,000 = 4.7619% (≈ 4.76%)
Later dilution when a new round closes:
1) Series A pre‑money: $5,000,000; new money: $1,000,000; Series A post‑money = $6,000,000
2) Existing shareholders are diluted by factor = old post‑money / new post‑money = $2,100,000 / $6,000,000 = 0.35
3) Angel’s new ownership = original ownership × dilution factor = 4.7619% × 0.35 ≈ 1.67%
Checklist for angels evaluating a deal (quick due diligence)
1) Team: founders’ track record, domain expertise, ability to execute.
2) Market: addressable market size and growth, competitors, defensibility.
3) Product: stage (prototype, revenue, customers), tech risk, roadmap.
4) Traction and unit economics: revenue, churn, gross margin per unit/customer acquisition cost.
5) Cap table and legal: existing ownership, option pool, outstanding convertible instruments.
6) Terms: valuation, liquidation preferences, rights that could limit exit.
7) Exit path: plausible buyers, IPO potential, timeline assumptions.
8) References: past investors,
, advisors, customers — speak with them. Verify claims on milestones, runway, customer retention, and references’ independence.
9) Red flags: unclear cap table, frequent founder turnover, refusal to share unit economics, undisclosed legal issues, overly aggressive valuation with little traction.
10) Practical exit assumptions: ask for realistic time horizon (often 5–10 years), likely acquirers, and potential exit multiples for the sector.
Key deal terms every angel should understand (short definitions)
– Pre‑money valuation: company value before the new investment. Post‑money = pre‑money + new investment.
– Equity dilution: reduction in percentage ownership after new shares are issued.
– Liquidation preference: payout order/priority at exit; e.g., 1x non‑participating means investor gets their money back first, then common shareholders share remaining proceeds.
– Pro rata right: right to invest in future rounds to maintain ownership percentage.
– Anti‑dilution protection: mechanisms that shield investors if future rounds price lower (full‑ratchet vs weighted average).
– Convertible note / SAFE: debt‑like or contract instruments that convert into equity at a future priced round under specified terms (cap, discount).
– Vesting and option pool: founder and employee equity typically vests over time; option pool size dilutes founders and investors depending on when it’s created.
Worked example — exit math and IRR (numeric)
Assumptions:
– Angel invests $100,000 at a pre‑money valuation of $1,900,000.
– Post‑money valuation = $2,000,000 → angel ownership = $100,000 / $2,000,000 = 5%.
– Company exits in 5 years for $50,000,000.
Proceeds to angel = 5% × $50,000,000 = $2,500,000.
Multiple on invested capital = $2,500,000 / $100,000 = 25×.
Approximate annualized return (IRR) = (25)^(1/5) − 1 ≈ 90% per year.
Contrast with a failed outcome:
– If the company fails and exit = $0, angel loss = 100% of capital.
Portfolio construction checklist (simple method)
– Target total angel capital: decide how much you can afford to lose (e.g., $200,000).
– Number of initial positions: diversify across sectors and stages; common rule: 20–30 deals.
– Initial check size: choose a standard (e.g., $5k–$25k) depending on capacity.
– Reserve allocation: set aside 2–4× an initial check per company for follow‑on rounds.
Example:
– $200,000 total → 25 initial deals at $4,000 each = $100,000 initial capital. Reserve $100,000 (avg $4,000 per deal for follow‑ons = 1× more).
Due diligence practical steps (quick checklist)
1) Financials: review cap table, cash runway, burn rate, revenue breakdown.
2) Legal: check incorporation, IP ownership, outstanding warrants/convertibles.
3) Customers: obtain customer contracts or access to reference customers.
4) Tech/IP: confirm patents/trade secrets or dependency on third‑party tech.
5) Team: validate founders’ resumes, talk to previous collaborators.
6) Market: assess TAM (total addressable market), competition, regulatory constraints.
Post‑investment actions (what angels typically do)
– Weekly/monthly updates: request short dashboards (revenue, burn, runway, KPIs).
– Offer expertise: introduce customers, hires, and future investors.
– Follow‑on discipline: decide in advance when you will participate in future rounds.
– Governance: exercise information rights responsibly; avoid micromanaging.
Common risks and mitigation
– High failure rate: expect many investments to return little or nothing. Mitigate by diversification and rigorous diligence.
– Dilution: plan for reserves and pro rata rights if you want to maintain ownership.
– Liquidity: venture investments are illiquid for years; treat capital as locked.
– Valuation traps: avoid overpaying based on hype; focus on traction and unit economics.
Tax and regulatory notes (general)
– Qualified Small Business Stock (QSBS, Section 1202) in the U.S. can offer favorable capital gains treatment for certain C‑corporation stock held >5 years; eligibility rules are specific.
– Accredited investor rules determine who can legally participate in many private deals (check SEC/regulatory guidance).
