No. The Partner Pages are based on ‘parent-child relations. You cannot create a child (program or event or page) without having a parent (organization page).
If you use the organization page to publish information about your program, it will not be shown in the overview of opportunities or event calendar and it will not be possible for users to find it searching by program type. This will negatively affect the visibility of your program on VC4Africa platform.
Ideally, you first create the parent page, by adding a page for your “organization supporting startups”. Once that is done, from within the admin dashboard of this organization page you can then “add a page” for your program or event (child pages). More detailed step-by-step guidance, you can find here.
