Startup Pitch for Investors

I needed to prepare a startup video pitch for Demo Day: explain the idea, show the product, and the real people behind it in 2-3 minutes. At first, I considered using animation, but after consulting with ORBIS Production, it became clear that a live video with real scenes was more effective. They helped me distill a complex technical topic into a simple story, added some graphics, and created a dynamic edit. I feel like this approach is what distinguishes a professional video production company in Switzerland, one that knows how to communicate clearly with investors. Has anyone else used similar videos as the main material for pitch sessions? Did it help you stand out from other projects?
