What would be the business implications to consider for going open-source?

What would be the business implications if a company like for example bubble.io converted their offering to an open-source project, where companies could host / run an app themselves or pay for a hosted option by bubble.io?

I'm asking because we have built something similar and we are contemplating the roadmap for us as a open-source project with a paid hosting service, vs just the paid hosting service. We also want to consider this from a technical and investor perspective.
