Does your deck answer following big questions about your start-up - (1) What is your promise to your target customers (2) Does your promise connects with target customers to help generate interest/ enquiry (3) How your solution delivers the promise without fail (4) How do you acquire customers (5) How big is the market and how scalable is the business. These are some of the questions deck needs to answer apart from lot of standard stuff. Would be happy to help further. All the best.
