US venture capital is the largest, deepest pool of startup funding in the world. In 2025, global venture funding reached $425 billion, according to Crunchbase’s annual funding report, with the US capturing $274 billion of that total, representing 64% of all global VC investment. For UK and European founders, the attraction is obvious: bigger checks, faster decisions, and investors who are comfortable backing truly ambitious bets.
But American VCs evaluate European companies through a specific lens, and most European founders are not pitching to that lens. The pitch that works in a London or Berlin meeting room often misses the mark entirely in San Francisco or New York, not because the company is bad but because the framing, the ambition calibration, and the operational credibility signals are wrong.
At Foothold America, we work every day with UK and European companies building serious US operations. We are not a VC firm and we do not advise on your fundraising strategy, but we see firsthand what operational foundations US investors expect to find, and we help our clients build them.
This guide is honest about what American investors actually look for and where European founders most often fall short. If you are at the earlier stage of planning your US move, our comprehensive guide to expanding to the USA from the UK covers the full picture from market entry to entity setup.
The Fundamental Calibration Gap
Before getting into specific criteria, there is a mindset difference between European and US fundraising that every founder needs to internalise. Get this wrong and everything else is noise.
US institutional venture capital runs on an explicit outlier model. A US VC managing a $300 million fund who takes 10% at Series A needs to see a credible pathway to a $3 billion or larger exit to return the fund from a single investment. They are not looking for good businesses with solid margins and steady growth. They are looking for companies that could be extremely large, and they are comfortable writing off the ones that do not get there.
USXP’s research, drawing on conversations with Wilson Sonsini’s Dan Glazer, captures the specific miscalibration European founders make: they pitch a solid, defensible, respectable business outcome to investors who are explicitly running for outliers.
The founders are surprised when Silicon Valley VCs say they are looking for a pathway to returning the fund, not stable growth or market leadership in a regional sense, but the kind of exit that returns or exceeds the entire fund. That gap, conservative European business ambition meeting extreme US return expectations, is the most common reason European companies do not get past first conversations with US investors.
The fix is not to inflate your numbers. It is to understand what total addressable market means to an American investor, to articulate your global ambition with confidence, and to build the US operational presence that makes that ambition credible rather than speculative.
What US Investors Actually Evaluate: The Core Criteria
1. US Market Traction
This is the single most important factor at early and growth stage. US investors want evidence that your product or service works in the American market, specifically, not just proof that it works somewhere.
Research from US Expansion Partners sets a clear benchmark:
- 5 to 10 paying US accounts demonstrates repeatability
- US revenue above 10% of total ARR signals real market pull
- Zero US customers is not automatically disqualifying but requires substantial additional US market validation in your pitch
Why does this matter so much? Because US and European buyers are different in ways investors know well. The US enterprise buyer moves fast in evaluation and slow in commitment. They respond to social proof and customer references in ways that European buyers often do not.
They expect direct, ROI-focused communication with short value-realisation timelines. A product that sells well to UK mid-market companies has not demonstrated it can sell to a VP of Sales at a 500-person company in Austin. US investors know this, and they look specifically for evidence that you have cracked the American buyer.
US traction is also not only about top-line revenue. Our Building US Investor Credibility guide covers the specific metrics and preparation steps that make a difference in investor conversations. It is about:
- The quality and recognisability of your US customers
- Whether your sales motion is repeatable without the founder closing every deal
- The speed of your US customer acquisition relative to your UK or European growth rate
- Net revenue retention from your US accounts
2. Founder Presence and Commitment to the US Market
At early and growth stage, founder presence in the US is close to a prerequisite for serious US investor conversations. It is not optional.
Earlybird Venture Partner Dan Lupu, quoted in Vestbee’s research on European VC advice for US expansion, is unambiguous: the CEO or a key founder must relocate or spend significant time in the US. It is about being close to customers, understanding the market firsthand, and being able to adapt based on direct feedback. You cannot iterate on feedback you never hear.
Frontline VC’s US Playbook is specific: founders should spend at least 50% of their time in the US in the first 18 months of expansion, and no less than 30%.
US investors are pattern-matching on commitment. A founder who is never in the US is demonstrating, through behaviour, that the US is not their top priority. American VCs do not back European companies that are running a lightweight US experiment while the real business is somewhere else.
Choosing which US city or region to base your early commercial presence in matters too, not just for operations but for investor perception. Our US Market Entry: East Coast vs West Coast vs Middle America strategy guide helps you make that call based on your sector and commercial goals.
What commitment looks like to a US investor:
- The CEO or a co-founder has physically relocated, or is substantially US-based for meaningful periods
- There is a clear US go-to-market owner on the ground, whether that is a founder or a strong US commercial hire
- The founder can speak to US customer feedback from direct conversation, not from a second-hand account
- There is a US operational infrastructure in place: employees, bank account, and a functioning commercial presence
3. Team Credibility for the American Market
US investors evaluate your team through a US lens. They want to know whether you can recruit, manage, and retain US talent. Whether you understand US sales culture, US compensation expectations, and how American enterprise buyers make decisions.
US experience on the founding team is a significant advantage at Series A, as USXP’s analysis confirms. If you or a co-founder has previously built and scaled a US business, that maps directly to the pattern-matching American VCs do. Lean into that story in investor conversations.
Knowing when to make your first senior US hire, and at what level, is one of the decisions that most shapes how investors view your US commitment. Our guides on when to hire your first US executive and C-Suite vs Regional Director leadership models cover both sides of this decision. If the founding team does not have direct US experience, the next strongest signal is senior US-based commercial hires:
- A VP of Sales or Head of Revenue based in a major US market
- A Chief Revenue Officer with an established US enterprise network
- A US-based Head of Customer Success managing your American accounts
These hires tell a US investor that you are serious enough about the market to compete for strong US talent, that you can attract and retain it, and that your US commercial operation has qualified local leadership. That is a material difference from a European founder who visits the US occasionally and manages US sales remotely.
4. Corporate Structure
The question of whether you need a US entity to raise from US investors is covered in full in our dedicated guide on US entity requirements for European fundraising. The short version:
- Seed stage: Many cross-border experienced US investors will invest in a UK or European entity directly
- Series A: Institutional US VCs, particularly West Coast firms without strong international portfolios, will frequently require a Delaware C Corporation
- Series B and beyond: Growth-stage investors are often more flexible if your traction is strong
The key point here is that corporate structure is a threshold issue, not the whole story. A Delaware C Corp does not make a weak company investable. And a company with strong US traction, a committed founding presence, and credible US team can often have the structural conversation as a negotiable closing condition rather than a pre-fundraise requirement.
Rockaway Ventures GP Petr Smid’s advice, quoted in Vestbee’s research: ensure your company is structured appropriately, such as being established as a Delaware C Corp, to facilitate investment. Do not let structure be the reason an investor passes. But do not do it speculatively before you have a committed investor either.
5. TAM and Ambition Framing
US investors want to back companies trying to become very large businesses. They are not interested in regional success stories, conservative projections, or sensible growth plans that cap at a respectable European exit outcome.
European founders consistently undersell themselves on this dimension, not because their ambitions are small but because European business culture tends toward qualification and caution. The same pitch that sounds professionally confident in a London fundraising room can sound timid on Sand Hill Road.
Total addressable market framing matters more in US fundraising than it typically does in European contexts. US VCs are calibrating whether your TAM is large enough to support the return profile they need from a portfolio company. If your market framing suggests you are building toward a $300 million outcome, you are probably not the right fit for a US institutional VC managing a $400 million fund. If you can credibly articulate a path to $5 billion or more, the conversation changes fundamentally.
This does not mean inventing numbers. It means thinking seriously about the global version of your market opportunity and presenting it with the confidence and precision that US investors expect.
US investors want to understand not just that you have US customers but how you are going to get more of them. The US go-to-market plan should be distinct from your European approach, not a copy of it.
Common mistakes European founders make in US GTM framing:
- Treating the US as a homogeneous market (it is not; Boston, Austin, and San Francisco can be very different buyer environments)
- Applying European sales cycles and decision-making frameworks to US buyers
- Underestimating US customer acquisition costs and the investment required to build brand recognition in a competitive market
- Assuming a European product will resell itself without Americanisation of positioning, pricing, and messaging
US investors who know their market will probe your GTM assumptions specifically. Be prepared to explain your ICP (ideal customer profile) for the US, your US channel strategy, how you are approaching US enterprise sales, and what your US CAC and LTV assumptions are based on.
US Employment Infrastructure as a Due Diligence Signal
This is consistently the most underestimated factor in investor readiness for European companies, and it is directly where Foothold America operates.
When a US investor gets serious about your company, their team or their legal counsel will look at your US operations in detail. Understanding how US VC funds evaluate deals helps you anticipate what they look for at this stage. Our US Venture Capital Guide explains the fund structures and due diligence processes that drive these decisions. They will examine:
- How your US employees are employed: are they on proper employment contracts compliant with the laws of their state, or are they contractors who should legally be employees?
- Workers’ compensation coverage: legally required in most US states and a red flag if absent
- Benefits structure: health insurance quality and employer contribution level directly affect your ability to attract and retain US talent, and investors know this
- Payroll tax compliance: are federal and state taxes being remitted correctly and on schedule?
- Employment classification: misclassified contractors are a known liability that can surface in due diligence
A company that has built its US employment correctly, with properly employed staff, compliant benefits, and clean payroll across all relevant states, signals to an investor that the management team understands what it means to operate in the US and has taken it seriously from the start.
A company with misclassified contractors, no benefits structure, or non-compliant payroll is a risk flag. It suggests the US operation has been built informally, and it raises questions about what else might have been handled loosely.
This is not about perfection. It is about demonstrating that you have built the foundations deliberately. And it is worth saying plainly: getting this right is also about your US employees as people. Their healthcare coverage, their 401k, their employment protections. Companies that take this seriously build better teams. That is a competitive advantage that shows up in everything from retention to investor due diligence.
Foothold America’s EOR service and PEO+ model for established US entities exist specifically to help international companies get this right. Our piece on how employer of record works and our PEO+ guide for foreign-owned businesses cover both models in full.
What Disqualifies European Companies Before the First Conversation
Understanding what US investors want is only part of the picture. Knowing what eliminates most European companies before serious conversations begin is equally important.
No meaningful US presence. Zero US customers, no US employees, a founder who has never spent extended time in the US, and no concrete US go-to-market plan is a pass for most institutional US investors before a second meeting. The US market is large, expensive to win, and deeply competitive. Investors want evidence you are already engaging with it seriously, not a plan to engage after the funding arrives.
European-calibrated ambition. If your financial projections top out at a level that represents a strong European outcome but a poor US venture return, you are pitching to the wrong audience. US institutional VCs need the outlier case.
A pitch that treats the US as a bigger version of Europe. The US enterprise buyer, US employment law, US compensation expectations, and US sales cycles all work differently from Europe. A pitch that assumes otherwise tells an experienced US investor that you have not done the work.
Cold outreach without a network. Industry data consistently shows that only around 20 to 25% of approaches to US VC firms even reach the pitch stage, and only a small fraction of those convert to investment. The US VC market runs on relationships. Warm introductions from portfolio companies, mutual advisors, law firms with deep VC relationships, or US enterprise customers are how real conversations start.
Sources of warm introductions that actually work:
- Law firms with cross-border VC practices (our trusted partner Wilson Sonsini is the most prominent example, but others exist)
- European VCs with established US LP relationships or US co-investment histories
- US accelerator alumni networks, including Y Combinator, Techstars, and sector-specific programmes
- US enterprise customers willing to advocate for your company with investors they know
- Other founders in your sector who have already raised US capital
Operational weakness in the US. If due diligence reveals misclassified contractors, non-compliant employment, no US banking infrastructure, or no financial reporting on your US P&L, it creates doubt about how seriously you are building in the US. The best pitch deck in the world does not override weak operational foundations when a VC’s counsel is doing a proper review.
How Foothold America Builds the Foundation US Investors Want to Find
When a US investor looks under the hood of your US operations, we want them to find a company that has built this properly.
What that looks like:
- US employees hired through a compliant employment structure with competitive benefits, medical insurance, 401k, and proper payroll in every state where you operate
- A US bank account and clean financial infrastructure through our Bank Representation service
- A US entity in place if and when the time is right, set up correctly from day one with our Entity Setup service
- Bookkeeping and financial reporting that gives you an accurate, clean view of your US costs, revenue, and burn
These are not peripheral considerations. They are the evidence that you are a serious, well-run business that has taken the American market seriously from the start. That is what US investors are actually looking for when they look beyond the pitch deck.
We work with founders and leadership teams who are building real US businesses, who are in active investor conversations, and who need their US operations to reflect the ambition of what they are building. We pick up the phone. We respond the same day. We bring real expertise from people who have spent years working at the intersection of UK, European, and American business culture.

Frequently Asked Questions: US Funding
Get answers to all your questions and take the first step towards a US business expansion.
Yes, increasingly so. US investors apply consistent criteria regardless of where a company is incorporated. US market traction, founder presence, team credibility, and a clear path to a large exit are the primary filters, not geography.
Not necessarily, but they help significantly. Research points to a minimum of five to ten paying US accounts as the benchmark for demonstrating repeatability. Zero US customers is not disqualifying, but it requires far more market validation elsewhere in the pitch.
At Series A and beyond from institutional US VCs, a Delaware C Corporation is the most common requirement. At seed stage, cross-border experienced investors often invest in UK or European entities directly. For a full breakdown, see our guide on US entity requirements.
They mean demonstrable presence: a founder or senior leader spending real time in the US, US-based employees, US customers, and a go-to-market approach validated with American buyers. Commitment shows through actions and infrastructure, not slides describing plans.
Very important, particularly at Series A. US experience maps to the pattern-matching American VCs do when judging whether a team can execute. If the founding team lacks it, senior US-based commercial hires are the next strongest signal.
Yes, but it depends on the investor. Cross-border experienced investors can invest directly into UK limited companies. US-focused investors who do not regularly invest internationally will often require a Delaware C Corp. Have the structural conversation early.
Pitching a solid, respectable business outcome to investors running for outliers. US institutional VCs need a credible pathway to a very large exit. European founders tend to understate ambition and frame market size too conservatively.
The key differences come down to risk appetite. US funds chase outlier returns, while European investors often take a more cautious approach focused on sustainable growth and valuation discipline. Understanding these market dynamics helps you frame your pitch for the right audience.
US venture capital funds weigh growth rate, US market traction, and total addressable market heavily. A strong valuation reflects the size of the opportunity, not just current revenue. American investors price for the outlier outcome, so ambition and evidence both matter.
Yes. Entrepreneurship, funding depth, and regulation vary widely across the European Union. Hubs in France, Spain, Germany, and the UK each have distinct ecosystems. That patchwork across member states is one reason many innovative companies look to the United States for scale.
Not always, but proximity helps. Many founders raising in the United States for the first time underestimate how much US presence matters. Some of Europe’s fastest-growing unicorns kept European roots while building serious US operations to satisfy investors.
US startups access deeper capital and higher valuations than most European markets offer. The scale of American venture capital funds plays a crucial role in why founders look west. Bigger cheques and outlier ambition define the difference.
Expect clean financial documentation, US employment contracts, payroll compliance records, cap table details, and entity paperwork. Investors reviewing US startups check that operations are built properly. Missing or messy documentation raises doubts and slows the round.
US institutional rounds are almost always denominated in USD. If your company operates across European markets, expect currency and reporting differences to surface in diligence. Clean US-dollar financial reporting makes conversations with American investors far smoother.
