So You Want to Be an Angel Investor? Start Here.

Angel investing has long carried an air of exclusivity.


You picture high-net-worth individuals writing six-figure checks into buzzy startups, getting early access to the next unicorn, and casually dropping “I invested early” into conversation.

But according to founders-turned-investors and operators actively writing checks today, that narrative is outdated and, frankly, misleading.


At Startup Boston’s recent webinar in partnership with the City of Boston, Chris Combs (Founder at LinkSquares & Angel Investor), Cammy Keiler (Marketing at Alembic & Angel Investor), George Le (Angel Investor) and moderated by Taylor Hardner (Venture Capital Intern at True Wealth Ventures | Director of Media for Girls Into VC) broke down what it actually looks like to get started - and what most people get wrong.


The takeaway? Angel investing is less about wealth and more about access, relationships, and how you choose to show up.


The First Check Might Surprise You

For many, the biggest mental barrier is simply getting started, but that first investment doesn’t have to be massive.


One panelist, Cammy Keiler, shared that her first angel check was just $250, a decision rooted more in belief than financial strategy.


It wasn’t about optimizing returns. It was about backing a founder and a mission she believed should exist. That moment reframed everything.


Instead of asking, “Am I qualified to invest?” the better question became: “Do I believe in this person and am I willing to learn?”


Myth: You Need to Be Ultra-Wealthy

Reality: The barrier to entry is lower than most people think.


While accreditation rules still apply in many cases (typically ~$200K income or $1M in assets), the practical entry point into angel investing is far more flexible than the stereotype suggests.


Checks can range widely:


  • $250 (yes, really)

  • $5,000–$10,000 (common early-stage entry)

  • Larger checks as part of structured rounds


More importantly, you don’t need to go it alone.


Angel groups, syndicates, and community-driven investing models are opening doors for first-time investors to participate alongside more experienced operators.


What Good Angel Investors Actually Do

Writing a check is the easy part. The real value? Everything that comes after.


The panel emphasized that strong angel investors:


  • Bring domain expertise (not just capital)

  • Open doors through their network

  • Act as advisors, mentors, and sounding boards

  • Learn alongside founders, not just from outcomes


As Chris Combs put it, the investment itself is often just the “price of admission” to being part of the journey.


In other words: If you’re only showing up with money, you’re missing the point.


Risk Is Real, But So Is Strategy

Let’s be clear: angel investing is risky. Most startups fail. Some go to zero.

So how do experienced angels approach it?


A few patterns emerged:


  1. Make More Bets, Not Bigger Bets. Instead of writing one large check, many angels spread capital across multiple startups, mirroring venture-style portfolio strategies.

  2. Only Invest What You’re Willing to Lose. This isn’t passive income. It’s long-term, high-risk capital.

  3. Think in Decades, Not Months. Returns often take 5–10 years, not 12–24 months.

  4. Invest in People, Not Just Companies. Even if a startup fails, relationships don’t and founders often come back stronger the second (or third) time around.


Deal Flow Doesn’t Come From Cold Outreach

If you’re wondering how investors actually find startups to invest in, the answer isn’t a spreadsheet of deals. It’s people.


Deal flow comes from:


  • Spending time with founders

  • Being active in the ecosystem

  • Joining angel groups or communities

  • Building relationships before a round exists


One panelist described it simply: Some investors “hunt.” Others “farm.”


The best opportunities tend to come from the latter, long-term relationship building, not one-off pitches.


Where Investors Are Paying Attention Right Now

While hype cycles come and go, a few themes stood out:


  1. Infrastructure Behind AI. Not just AI apps—but the systems enabling them (compute, tooling, workflows)

  2. Adjacent Opportunities. “Don’t invest in the coffee—invest in the coffee sleeves.” Translation: the biggest wins are often around the trend, not in it.

  3. Femtech & Female Founders. Still significantly underfunded—and widely seen as an untapped opportunity

  4. Non-Consensus Bets. The best returns often come from investing in what others are ignoring


So… What Should You Do Next?

If you’re curious about angel investing but haven’t taken the leap yet, the panel offered a simple starting point:


Do one thing this month:


  • Define how much risk you’re comfortable taking

  • Learn how to diligence a startup

  • Spend time with founders without an agenda

  • Join an angel group or attend pitch sessions

  • Start small, but start


Because there’s no official moment where you’re “ready.” No badge, no certification, just a decision to participate.


The Bigger Picture

Angel investing isn’t just about financial returns. Instead, it’s about:


  • Backing ideas before they’re obvious

  • Supporting founders through uncertainty

  • Contributing to the ecosystem you’re part of


Or, as one panelist put it: You’re not just investing in a company, you’re investing in someone’s career.


And that changes how you show up entirely.
