For European startups, expanding into the UK or US can unlock access to larger markets, deeper investor pools, and faster growth – but it also introduces legal, structural, and fundraising complexity.

Founders often underestimate how different the UK and US ecosystems are from Europe. From company structures and tax to investor expectations and fundraising mechanics, getting it wrong early can slow growth or create costly clean-up later.

In this video, SeedLegals CEO Anthony Rose shares practical guidance on how European companies should think about UK and US expansion, including how to structure early fundraising, avoid common mistakes and prepare for future investors from day one.

Key takeaways 

Expanding to the UK or US requires early planning

• Moving into the UK or US isn’t just about access to new markets – it affects how your company is structured and how you fundraise
• Early decisions can make future fundraising much easier (or much harder)

Investors expect familiar, clean company structures

• UK and US investors look for setups they recognise and trust
• Fixing structural issues after you’ve raised is time-consuming and costly

Fundraising works differently across regions

• European approaches don’t always translate directly to the UK or US
• Understanding local investor expectations helps founders raise with more confidence

How fundraising norms differ from Europe

• UK and US investors often expect more standardised terms and familiar legal frameworks
• Understanding local fundraising conventions helps founders raise with more confidence
