Web Application prototypes help entrepreneurs get high fidelity simulations in front of users and investors quickly and easily. SparkPop meets with product owners to work out requirements and design, but instead of building the app in expensive code, SparkPop created a simulation that provides users a close simulation of the real app. Should user feedback require changes, the prototypes are simple and cheap to edit without racking up developer costs. Prototypes are a great way to test a concept before making a large financial commitment.
