I've always liked having one core audience & many supporting audiences for a product story... think about it. Movies with multiple heroes are confusing.
Pick your core audience and tell the product story for them. If you have multiple supporting audiences, then describe how everyone can work better (using your product) with related audiences.
As an example, at Twilio we launched the Enterprise Plan. It provided capabilities for Finance, Security, DevOps, IT, etc. We messaged the product for developers because they were our primary audience. We talked about how the Enterprise Plan helped developers pick the tools they want, while satisfying concerns from the procurement, security and operational teams. It worked well. Developers sold the product for us :).
