It would be beneficial to have a screen that's focused on orienting folks to what the product is and has a space for linking the key documents for quick access by the team members thats managed outside of Aha. Pitch decks, salesforce, rosters, etc.

The workspace overview page (Info > Overview.) This provides a description field where you can share important information related to the product.
Workspace notes. Notes provide wiki-like functionality for creating and sharing product-related information.
