I don't know of any templates, but I have read a couple of books by Edward Tufte and his books have really helped me with my presentations and how to present information visually. Especially more complex subjects like architecture.
You might consider using an infographic approach. A diagram that can explain the platform while focusing on the problems that you are solving. Always be telling a story that everyone can get excited about.
Keep it simple and easy to understand. If you get too technical, you will lose the audience.
In all the presentations that I have done, the audience always get a bit bored when you hit the technology section. This is because as humans, we are wired to be receptive to stories. We like a good story. Technology is boring for most people. You can have a whitepaper for those that really want to dive in deep into your technology, but for most, just keep it light, fun and compelling.
The key is always to keep it simple. Don't overload your deck with too much information. Steve Jobs was the master of this: http://www.forbes.com/sites/carminegallo/2012/10/04/11-presentation-lessons-you-can-still-learn-from-steve-jobs/
Guy Kawasaki also has some great advice on pitching as well
