How long should my pitch deck actually be?

Keep it to 10-12 slides. Investors spend an average of 3 minutes and 44 seconds on a deck before deciding to book a meeting or pass. Focus on the problem, your unique solution, and clear evidence of traction. If you can't explain why your business wins in ten minutes, your narrative is too messy.

What is the most common mistake founders make in a pitch?

Over-complicating the tech while ignoring the business model. Founders often spend 80% of their slides on how the product works rather than how it makes money. You need to prove there is a massive, addressable market and a clear, repeatable path to capturing it while keeping your burn rate under control.

Do I really need a full financial model for a seed round?

Yes, but not because the numbers will be 100% accurate. A robust model demonstrates you understand the drivers of your business, like CAC, LTV, and churn. British Business Bank data shows that prepared founders are significantly more likely to secure equity. It proves you are a operator, not just a dreamer.

How do I handle the 'competition' slide?

Never say you have no competition; it makes you look naive. Instead, map the landscape and show exactly why your approach is fundamentally different or better. Focus on your 'unfair advantage'—whether that is proprietary IP, a unique distribution channel, or a team that has successfully exited in this space before.

Should I share my deck before the meeting?

Always send a 'teaser' version. This should be a high-level PDF that sparks curiosity without giving away every secret. Save the deep-dive data and full financials for the follow-up. Your goal with the initial deck is to sell the meeting, not the entire company in one go.
