If you really want to be successful here, go to events the incubator is holding and make sure to connect with the program manager. Ask really good questions to determine what the questions on the application really mean. For example, the meaning of "impact" in the education space has changed overtime behind the scenes with none of us on the outside knowing about it. It used to mean financial returns, then it meant scalable reach so PR could tout millions served, now it means something else akin to "real impact" which is so nebulous these committee's will only "know it when they see it" kind of thing. Point is, they don't even know!
Usually program managers will offer to talk about your company with you in light of their program. This is extremely helpful since you will understand what they emphasize. They will also offer their email so you can follow up if you have any questions.
... and p.s. - don't worry about applying too early or making any mistakes, if you do finally get accepted they'll be impressed with the "progress you've made".
