Long term vision should support both but in short term you can focus on your hypothetical ICP or beta customers. If you are focused on customers who prefer self hosting, that could be your MVP version but in the long term cloud may give you scale. Some upfront Pros and Cons of Self hosted vs Cloud.
Self Hosted ( As assuming stand alone or cloud self hosted)
- Pros: Cost to serve customer is less for you as you pass on infra cost to the customer.
- Cons : Maintenance and continuous support will cost you more as every deployment release and support will be specific to customer.
Cloud
- Pros : Easier to get started and scale if it is a self serve product.
- Cost : Infra cost is added to your cost to serve customer.
