I find that pitch decks to investors fail to articulate how they will maintain a market lead and build barriers to entry around their business over time, as more competitors emerge. We teach 17 ways to increase SCA at The CEO Boot Camp and in our scaling consulting work.

I would recommend adding two additional slides to the standard 10-12 most have in their decks. This will impress investors far more than some fancy graphics or massive TAM market claims. Slides to add:

1. Sustainable Competitive Advantage (SCA) - How will you evolve your barriers to entry over time. The "Moat" which can create higher PE ratios. Product roadmap and innovation? IP? Brand? Partnerships? Etc.
2. Market entry strategy, which is not the same as Go to Market strategy. This shows expanding markets, niches and the $1B market opportunity - which NO startup should ever enter initially because then they are competing with giants on day #1. A slow suicide strategy.
