What is Angel Investing?
Angel investing is the practice of providing capital to early-stage startups in exchange for equity ownership. Unlike venture capitalists who manage institutional funds, angel investors typically use their personal wealth to back entrepreneurs they believe in.
The term "angel" originated from Broadway, where wealthy individuals would provide financing for theatrical productions. Today, angel investors play a crucial role in the startup ecosystem, often being the first professional investors in a company's journey.
Key Characteristics of Angel Investing:
- Typically invest $10,000 to $500,000 per deal
- Focus on seed and pre-seed stage companies
- Often provide mentorship alongside capital
- Higher risk, higher potential reward profile
- Long-term investment horizon (5-10+ years)
Who Can Be an Angel Investor?
In the United States, angel investors are typically "accredited investors" as defined by the SEC. This generally means individuals with:
- Annual income exceeding $200,000 ($300,000 with spouse) for the last two years
- Net worth over $1 million, excluding primary residence
- Certain professional certifications (Series 7, 65, or 82)
However, with the rise of equity crowdfunding platforms, non-accredited investors can now participate in startup investing with certain limitations under SEC Regulation Crowdfunding.
Finding Investment Opportunities
Deal flow is the lifeblood of angel investing. Here are the most effective ways to find quality investment opportunities:
1. Angel Groups and Syndicates
Organizations like Tech Coast Angels, Golden Seeds, and Angel Capital Association provide vetted deal flow and the opportunity to co-invest with experienced angels.
2. Online Platforms
Platforms like AngelList, SeedInvest, and Republic have democratized access to startup investments, offering curated deals and syndicate investing options.
3. Personal Network
Many of the best deals come through warm introductions. Building relationships with other investors, entrepreneurs, and accelerator programs expands your deal flow significantly.
Due Diligence Process
Thorough due diligence is essential to making informed investment decisions. Here's a framework for evaluating early-stage startups:
Team Assessment
- • Founder background and experience
- • Team completeness and dynamics
- • Domain expertise
- • Commitment level
Market Analysis
- • Market size (TAM, SAM, SOM)
- • Growth trajectory
- • Competitive landscape
- • Timing considerations
Product Evaluation
- • Product-market fit signals
- • Technology differentiation
- • Scalability potential
- • Defensibility/moat
Financial Review
- • Business model viability
- • Unit economics
- • Burn rate and runway
- • Funding history
Investment Instruments
Angel investors typically use several types of instruments to invest in startups:
SAFE Notes (Simple Agreement for Future Equity)
Created by Y Combinator, SAFEs are the most popular instrument for early-stage investing. They convert to equity in a future priced round, typically with a valuation cap and/or discount.
Convertible Notes
Similar to SAFEs but structured as debt with an interest rate and maturity date. They convert to equity at a future financing event.
Direct Equity
Purchasing shares directly at a negotiated valuation. More common in priced seed rounds where the company's value has been established.
Portfolio Construction
Building a diversified angel portfolio is crucial for managing risk. Most successful angel investors follow these principles:
Portfolio Best Practices:
- 1Minimum 20-30 investments — Diversification is key given the high failure rate of startups
- 2Consistent check sizes — Avoid over-concentrating in any single investment
- 3Reserve for follow-ons — Keep 30-50% of your capital for follow-on investments in winners
- 4Diversify across stages — Mix pre-seed, seed, and Series A investments
- 5Sector variety — While specialization helps, some diversification across sectors reduces risk
Performance Metrics
Understanding how to measure your portfolio performance is essential. Here are the key metrics every angel investor should track:
MOIC (Multiple on Invested Capital)
Current Value / Amount Invested
A 3x MOIC means your $50,000 investment is now worth $150,000
IRR (Internal Rate of Return)
Annualized rate of return accounting for time
A 3x return over 5 years = ~24.6% IRR
TVPI (Total Value to Paid-In)
(Distributions + Remaining Value) / Total Invested
Includes both realized and unrealized returns
DPI (Distributions to Paid-In)
Total Distributions / Total Invested
Shows actual cash returned to you
Exit Strategies
Angel investments are illiquid by nature. Understanding potential exit scenarios helps set realistic expectations:
- Acquisition: The most common exit for startups. A larger company buys the startup, providing liquidity to investors.
- IPO: Rare but potentially lucrative. The company goes public, allowing investors to sell shares on public markets.
- Secondary Sale: Selling your shares to another investor before an IPO or acquisition. Increasingly common with platforms like EquityZen.
- Buyback: The company or founders buy back your shares. More common in profitable, self-sustaining businesses.
