Ask HN: Should we offer selfhosted or cloud version first of B2B SaaS?

Hello, I'm currently working with my brother on a code scanning tool for B2B and we were thinking about the hosting models, we want to offer cloud version and self hosted because some companies don't want their data in the cloud. The question is which model should we start with? should we offer both at the beginning? What are the pros and cons of each one ? And are companies willing to use cloud or self hosted version (self hosted will cost more than our cloud version) Thank you in advance
