Because their product which is based on my base product will have a different name and branding. It won't be affiliated with my product so I'm not sure how it leads to faster ROI. The good thing is that my product will be based by many enterprise companies so will become more stable.

A similar example I can think of is the relation between SQLStream and AWS Kinesis Analytics. Kinesis Analytics is based on SQLStream but people who use AWS don't know it; however SQLStream uses the name of AWS as their client in their website. It's likely that AWS re-branded SQLStream as Kinesis Analytics as a different product and provided it to their user as a managed service.
