Top 10 Lessons from Angel by Jason Calacanis

1. Invest in the Founder, Not Just the Idea

A startup’s success hinges primarily on its founder’s vision, resilience, and execution ability. Prioritize people over products.

2. Get Comfortable with Risk and Ambiguity

Angel investing is inherently risky and uncertain. The key is disciplined risk management, not risk avoidance.

3. Build Relationships Early and Authentically

Network relentlessly and cultivate genuine connections with entrepreneurs, other investors, and industry insiders. Deals flow through trust.

4. Due Diligence Is Non-Negotiable

Thoroughly vet the team, market potential, competition, and business model before committing capital. Gut feelings must be backed by data.

5. Invest in Markets You Understand

Focus your investments on industries where you have expertise or insights. Deep knowledge enhances your ability to spot winners.

6. Be Prepared to Follow On

Successful angel investors often participate in multiple funding rounds. Having capital available for follow-up investments is crucial to protect and grow your stake.

7. Timing Matters—But Patience Is a Virtue

Early entry can yield outsized returns, but startups take time to mature. Adopt a long-term horizon and avoid chasing quick exits.

8. Diversify Across Startups, Not Just Industries

Mitigate risk by spreading your capital across multiple startups. A single winner can outweigh numerous failures.

9. Learn to Say No Often

Not every promising startup is the right fit. Saying no quickly preserves your resources and sharpens your investment focus.

10. Be an Active, Value-Adding Investor

Beyond capital, provide mentorship, introductions, and strategic advice. Your involvement can increase a startup’s odds of success and your returns.
