“Our technology saves costs!”. In the early days of a startup it is often not possible to quantify exactly what the cost benefits of your product will be. And many decks I see reflect that uncertainty. In the same deck you can see:
Slide: cost is a big problem
Slide: a technology gap makes users lose a lot of time
Slide: our technology can deliver double the power at the same cost
Slide: cost savings at our pilot client were 30%
Per transaction cost went from $1.1 to $1.2 at 40% more power
Investors will forgive you if things are not completely certain at the moment, but get confused when you throws different stories at them.
All the points above can be rooted in one single, consistent story. Maybe it is better to phrase exactly what is happening with your product, and then show a number of scenarios who it could create value for clients.
