1.) You have a lot of nice tech, but think long and hard about the social dynamics and how you can get from A->B. By far, the tech will be the easy part. Convincing established scientists and up-and-coming scientists who need publications in quality journals is much, much harder. As another comment says, try finding a niche first and build out. Particularly some less established fields.
2.) You mention hiring engineers, designers, devops, QE. This points to solving a social problem with technology. Consider marketing, or even social scientists who can guide you in understanding the communities you are attempting to influence. Become embedded in those communities, build trust, attend (and maybe sponsor) conferences, and then branch out.
3.) Sort of a pet peeve of mine (among many): You talk about making the studies accessible to the lay public (in terms of understandability). I feel this is a bad trend. Scientists need a way to talk to each other in their own language, without needing to lay out all the context every time. Academic publishing is that avenue. I have published many articles that will not be understandable to anyone without at least 2 years of graduate school in the field. They aren't groundbreaking, but can still be important. Science is very incremental in many areas. Although I 100% agree that it should be open and free.
For the lay public, there are always books, blogs, and pop-sci news that put it into context.
Anyway, I wish you success (truly, we need improvement over the status quo). It's easy for people to criticize, but think of all the things we don't criticize (which means we approve of them!)
