There are two ways you can go about thinking of this: 1. Technology and Applications that need improvement and 2. Technology and Applications that haven’t been created yet.
1. I think that Lyft has the potential to grow as a company, especially with all the controversy centered around their competitors (sips tea). I could see them doing a collaboration with a music streaming service and potentially getting into the food delivery service. I think the time to invest is now (I am not liable for any losses that may occur as a result of your investments 😐)
2. For college students, the site Blackboard is used a lot. There should be a system that takes assignments posted on the Blackboard and integrates them into calendars so that upcoming deadlines were more apparent. You can have that one for free 😉
