Frequently Asked Questions (FAQ)
What's the first step to approach an investment firm?
Start with thorough research. Identify firms that align with your project's stage, sector, and funding needs. Look for a warm introduction through your network if possible. If not, carefully craft a concise and compelling introductory email or use the submission forms on their websites. Ensure you have a polished pitch deck ready.
How important is a pitch deck?
Extremely important. A pitch deck is your project's calling card. It should clearly articulate the problem you're solving, your solution, market size, business model, traction (if any), team, financial projections, and funding requirements. Keep it concise, visually appealing, and data-driven.
Do London VCs only invest in UK companies?
While many London-based VCs focus heavily on the UK and Europe, several top firms (like Accel, Index Ventures, Atomico, Creandum) have a global mandate or strong international connections and invest worldwide. However, firms like LocalGlobe or those leveraging UK-specific schemes (EIS/VCT) might have a stronger UK focus. Always check the firm's specific geographical focus.
What are investors looking for besides a good idea?
Investors look for several key factors:
- Strong Team: Experienced, resilient, and capable founders and management team.
- Market Opportunity: A large, growing, and addressable market.
- Scalability: A business model that can grow significantly and efficiently.
- Traction: Evidence of product-market fit, user growth, or revenue (especially for later stages).
- Competitive Advantage: A clear differentiator or "moat" protecting the business from competition.
- Exit Strategy: A plausible path for investors to realize a return on their investment (e.g., acquisition, IPO).
