thats not how that works. First you need an organization to build this stuff themselves; Then you need other organizations that start using that stuff because it is good enough; Then at some point you get to an amount of organizations that someone figures it starts to make sense to offer things as a service which amps up the quality and allows for a large number of organization to start adopting things. You can't just go: Someone go build stuff and offer it as a service, and then suffer crickets for eternity

It's not rocket science. And it's already an established business model. See Buffer etc.
