Last month, Foundervine brought together 16 founders for an intimate dinner hosted by Wilson Sonsini at their London office, Eden House, Spital Square, to explore one of the most pressing questions facing ambitious businesses today: What does it really take to succeed in the United States?
As Foundervine's work increasingly spans both sides of the Atlantic, the discussion could not have been more timely. Some founders within our community have already established operations in the US, while others are actively exploring whether expansion forms part of their future growth strategy. Having recently launched Foundervine Accelerator USA in Washington DC, we are equally focused on helping bridge the gap between the UK and US startup ecosystems.
Hosted under the title Coming to America: Transforming Companies through US Expansion & Fundraising, the evening brought together founders at different stages of their international growth journey. The discussion was led by Daniel Glazer of Wilson Sonsini, whose firm has a long history of supporting innovative companies and regularly advises UK businesses seeking to expand into the United States.
One of the strongest themes to emerge throughout the evening was that, while the UK and US share a common language, they often operate very differently in practice.
Founders discussed how business culture, communication styles, investor expectations and approaches to growth can vary significantly between the two markets. Success in the US is rarely achieved by simply replicating a UK strategy on a larger stage.
This point was reinforced by a founder who had experienced both markets first-hand. Having previously lived and worked in the United States before relocating to the UK, they reflected on the intensity of American business culture, where networking, business development and promoting your company are often constant activities. While they appreciated the greater emphasis on work-life balance found in the UK, they also recognised the United States as an exceptional market for ambitious businesses willing to adapt to its pace and expectations.
Fundraising emerged as one of the most discussed topics of the evening.
A key insight shared during the discussion was that US investors are often attracted to ambition and scale. While strong fundamentals remain important, founders seeking to raise capital in the United States must also be prepared to articulate a compelling vision for growth and demonstrate the size of the opportunity they are pursuing.
For many founders, this represents a subtle but important shift in mindset. Understanding how investors evaluate opportunity, market potential and long-term growth prospects can play a significant role in determining fundraising success.
The conversation also explored customer acquisition and market entry.
While the size of the US market creates significant opportunities, founders were reminded that larger markets often come with larger competitive landscapes. Businesses expanding from the UK may find themselves competing not only against local providers within a particular city or state, but also against companies operating nationally across multiple regions.
The United States remains one of the world's largest consumer markets, creating considerable opportunities for businesses that can establish themselves successfully. However, founders were encouraged to approach expansion with a clear understanding of the competitive environment and the resources required to succeed.
Perhaps the most important lesson of the evening centred on a deceptively simple question: what are you actually trying to build?
Daniel encouraged founders to think carefully about their long-term intentions before making decisions about expansion.
Do you want to become a US-first company, with headquarters, leadership and major operations based in the United States? Or do you want to remain a UK-based business with a presence in the US that supports growth without fundamentally changing the centre of gravity of the company?
The answer to this question has significant implications for how a business positions itself, where it invests resources, how it approaches fundraising and what infrastructure it builds over time.
Rather than viewing expansion as a single decision, founders were encouraged to view it as a strategic choice about the future identity of their business.
For Foundervine, the dinner reflected a broader commitment to supporting founders as opportunities become increasingly global.
As more businesses within our community establish operations overseas, and as Foundervine continues to expand its own presence in the United States, we see a growing need to help founders access practical insights, trusted networks and honest advice.
Expansion into the US can unlock significant opportunities, but it is not the right path for every business. Our role is to help founders understand the realities, avoid common mistakes and make informed decisions that align with their ambitions.
A special thank you to Daniel Glazer and the Wilson Sonsini team for hosting the discussion and sharing their expertise. Their insights provided founders with a valuable perspective on navigating one of the world's most dynamic and competitive markets.
We look forward to continuing to connect founders, investors and ecosystem leaders across both sides of the Atlantic.
