International Investing: Build a Global Angel Portfolio

Brian Nichols is the co-founder of Angel Squad, an angel investing community where aspiring and active angels learn from Hustle Fund’s approach, review curated deal flow, and connect with peers.

Your startup portfolio can span three continents and still depend on the same customers, currency, and funding market. Expanding beyond your local network takes more than adding countries to a spreadsheet. You need a way to understand what each company adds to the portfolio and which risks travel with it.

What international investing means for an angel portfolio

International investing adds exposure to companies and markets outside your home country. Geographic diversification spreads investments across those markets with the aim of reducing dependence on one economy. Geographic variety alone does not guarantee that reduction.

For public-market investors, that exposure can come through foreign stocks, mutual funds, or exchange-traded funds (ETFs). ETFs trade on an exchange and can track foreign stock or bond portfolios.

In the US, international funds generally focus on companies outside the US; global funds can include US companies too. The US Securities and Exchange Commission (SEC) describes these international investment options.

An angel portfolio is a different part of your financial life. You're investing in private startups, often before the business model is proven. A handful of overseas startups cannot provide the breadth of a broad international fund, and public-market allocation rules don't translate directly into an angel-investing plan.

A geographically agnostic approach means you consider a startup on its merits regardless of where its founders live. You still need to understand its geography. Customer demand, operating costs, currency exposure, and access to future funding can all depend on specific markets.

We start with the portfolio. Our co-founder and general partner Elizabeth Yin writes in Democratizing Knowledge, “Don't try to pick a co. Select a portfolio.” Geographic exposure is one part of that discipline, alongside sector, stage, and the amount you invest.

Why invest beyond your local startup network?

Your professional network shapes the companies you see. A software operator in San Francisco may encounter plenty of startups selling to other US software companies. A founder serving manufacturers elsewhere may solve a problem that never appears in that operator's inbox.

Looking more widely creates opportunities to learn about different customers, distribution channels, and business models. You can keep your sector expertise while expanding where you apply it. An operator who understands business software might evaluate companies serving logistics firms in several markets without pretending to understand every local industry.

The portfolio benefit depends on whether those businesses have different economic drivers. Two startups in different countries may rely on the same enterprise technology budget. Two companies headquartered in the same country may sell to very different customers abroad.

Diversification can reduce dependence on an individual company or market. It cannot prevent losses across the portfolio. Startup investing remains speculative and illiquid, meaning you may have no practical way to sell when you want to.

Any startup investment can fail, and you can lose the full amount invested. The SEC's private-placement risk guidance warns about total loss, limited disclosure, and potentially indefinite holding periods.

Map economic exposure before counting countries

A company's headquarters is a useful address. Its incorporation country identifies its legal home. Neither tells you everything about where the business earns money or what could disrupt it.

For every prospective investment, record four kinds of geographic exposure. Keep the legal domicile in a separate field so it doesn't stand in for the business analysis.

1. Customers. Record where paying customers are located and which markets contribute revenue. For a pre-revenue company, distinguish current pilots or demonstrated usage from countries on the expansion roadmap. A planned market is still an assumption.
2. Operations. Identify where the founders, employees, important suppliers, and essential infrastructure operate. A distributed team can still depend on one supplier or one location for a critical activity.
3. Currency. Record the currencies in which the company earns revenue and pays major costs. A check denominated in US dollars doesn't make the underlying business immune to currency movements.
4. Funding. Identify the markets and types of investors the company expects to approach for future rounds. Record potential acquisition markets separately, with the understanding that neither another round nor an exit is assured.

Funding geography matters even when customers are elsewhere. A study of US startups, revised in 2024 by Jun Chen and Michael Ewens, found that a rule-driven contraction in regional venture capital was accompanied by lower startup financing and valuations. Some startups also moved out of affected states. That evidence supports including funding access in your geographic analysis, rather than treating the customer market as the whole story.

Consider a hypothetical portfolio with startups headquartered in London, Singapore, and Toronto. All three sell to US venture-backed software companies, collect dollars, and expect US venture firms to fund their next rounds. The founders live in different places, but a contraction in US startup spending could hurt all three at once.

A startup selling workflow software to European manufacturers might add a different customer exposure. It could also introduce euro revenue, local procurement requirements, and operating risks you understand less well. That is a tradeoff to assess, not proof that the new investment makes the portfolio safer.

Build a geographic thesis you can explain

Your geographic thesis is a short statement of where you want exposure, why it fits your experience, and which risks you're willing to accept. It should help you pass on deals as well as identify them.

Start with the expertise you already have. Then describe the customer or operating difference you want to understand. “I know logistics software and want to evaluate businesses serving manufacturers outside the US” gives you a more useful starting point than “I want one startup on every continent.”

Use these questions to make the thesis specific:

• Customer advantage. What does this team understand about its customers that a less local competitor might miss? Look for evidence in product decisions, customer relationships, and sales results.
• Distribution. How does the company reach buyers, and can that route work beyond its first market? A successful launch in one country doesn't establish demand in the next.
• Operating advantage. Does access to relevant talent, suppliers, or infrastructure improve the business after coordination and other costs? Country-level cost stereotypes won't answer that.
• Shared downside. Which existing holdings would suffer from the same customer-budget cut, currency change, funding shortage, or policy change?
• Knowledge gap. Which unfamiliar market assumptions need evidence from customers or independent local operators before you can form a view?

Keep sector, stage, and geography visible together. Expanding abroad into the same sector can preserve your analytical strength. Adding unfamiliar countries, sectors, and business models simultaneously makes it harder to know what you're underwriting.

Measure concentration by capital as well as company count

A country count gives every company equal weight. Your dollars may tell a different story.

In a hypothetical, simplified capital-allocation example, imagine ten initial checks of $2,000 each. Six companies earn most of their revenue in one market. Those six account for $12,000 of the $20,000 invested, or 60% of initial capital. If you later invest another $10,000 in one of those six, the same customer-market grouping accounts for $22,000 of $30,000, about 73%.

The company count hasn't changed. Your committed capital is more concentrated. These figures describe investment amounts, not portfolio value or expected returns; they exclude fees and assume the customer-market classifications remain unchanged.

Keep both measures in your records:

• Company count. How many holdings share a customer market, operating dependency, or financing source?
• Capital invested. How much initial and follow-on capital has gone into those holdings?

Treat the geographic labels as overlapping risk categories. A company can have US customers, an Indian operating team, and European funding relationships. Those exposures shouldn't be forced into one country bucket or added together as though they were separate investments.

Set your startup-investing budget, investment pace, and follow-on approach before a compelling deal arrives. There is no universal international percentage for an angel portfolio. Your capacity for loss, other assets, expertise, and available opportunities matter more than a tidy map.

Expand deal flow and keep your diligence standards

A wider portfolio starts with a wider set of companies to consider. Relationships with investors, accelerators, customers, and operators in a target market can add context you won't get from a pitch deck.

Learn how each contact knows the company and whether they have a financial interest in the round. Local familiarity is useful evidence; it doesn't make someone independent or qualified to advise on legal and tax issues.

In Angel Squad, we combine curated deal flow from Hustle Fund, our early-stage venture firm, with investor education and peer connections. That gives you more opportunities to practice evaluating companies and discuss unfamiliar markets. You still decide whether an available investment fits your own portfolio.

Distance changes how you gather evidence. It shouldn't lower the standard of evidence. Keep the remote work focused on the business:

• Documents. Request the pitch deck, financial records, financing documents, ownership records, and supporting customer evidence relevant to the company's stage. A tidy data room is convenient. Missing or inconsistent information needs an explanation.
• Product. Watch the team demonstrate the workflow a customer uses. Separate what works today from prototypes and promised features. Presentation polish and a glitch-free video call say little about customer demand.
• Customers and usage. Discuss the problem with customers where permission allows. Reconcile claimed active users with underlying product analytics and comparable groups of users over time. Search interest and website-traffic estimates cannot substantiate a claimed active-user count.
• Team. Include the relevant co-founders or team leads in substantive discussions. Understand responsibilities, decisions, and what they've delivered. Arrange reasonable meeting times across time zones; fatigue at an inconvenient hour isn't evidence of founder quality.
• Local assumptions. Ask independent operators about buying behavior, procurement, distribution, and competitive alternatives. Keep confidential customer and company information protected when gathering references.

Our co-founder and general partner Elizabeth Yin writes, “Charismatic people can really fool you.” Record what the team has shipped, sold, and learned so the pitch doesn't become your entire investment case.

Use a consistent investment memo template to separate supported facts, founder claims, and your assumptions. Add a short paragraph explaining how the proposed check changes your geographic exposure. A strong company can still add more of a risk you already own.

Review the portfolio as companies change

A startup's geography can change after your investment. It may enter another customer market, move part of its team, change suppliers, or begin relying on a different funding ecosystem.

Keep a standard record of each investment, its terms, capital invested, exposure categories, supporting evidence, and next expected update. Agree on a sustainable founder-update cadence and communication channels that work across time zones. Ask for changes in customer mix, major operating dependencies, cash needs, and financing plans.

Revisit the exposure map before a follow-on investment and after a material business change. If several companies expand into the same market, your portfolio may become more concentrated without any new holdings. Private startup investments may be difficult to sell, so future checks and follow-on decisions are often the practical opportunities to change your exposure.

Keep geographic fit separate from transaction suitability

A business can fit your geographic thesis while the investment itself is unsuitable for you. Incorporation location, investor eligibility, governing documents, legal rights, tax obligations, and currency restrictions require separate attention. A syndicate, investment platform, or US-dollar payment doesn't settle those questions.

The SEC identifies information differences, currency movements, political and economic events, and potentially limited legal remedies among the risks of international investing. Geographic diversification leaves those risks in place alongside the underlying risk of startup failure.

Seek independent review from qualified legal and tax professionals for the specific offering and your circumstances. Membership in an investing community doesn't establish eligibility, guarantee an allocation, or make a transaction appropriate.

Get more perspectives before your next investment

If your deal flow comes from the same small circle, broader exposure starts with broader conversations. Apply to Angel Squad to learn with other angels, discuss startup decisions, and build relationships beyond your existing network.

This is general education, not investment, legal, or tax advice. Startup investments are speculative, illiquid, and long-term; you may lose all invested capital. Seek independent advice from qualified professionals about any specific investment and its governing documents.
