I’d like to add one more tip: good design. I’ve seen and designed many decks for startups and some engineers pay zero attention to design. Sure if you have insane traction or other extraordinary data points it becomes less of an issue. But the investors, like yourself, are human beings who want things to look clean, neat and be clear. Nice design doesnt mean add nice colors. It means to make it a joy to go through with visuals of your product, clear font and font color selection, consistent branding etc. don’t waste too much time on the design but do treat your deck as a product of its own.
If you need any advice, feel free to ping me.
