As the business scales, additional rounds (Series B, C, etc.) may follow, involving more significant investments and higher valuations.

Legal and Financial Frameworks
The UK provides an investor-friendly environment with established legal standards, tax relief initiatives like the Enterprise Investment Scheme (EIS), and access to skilled legal and financial advisors.
