Andrew, it eally depends on the stage of the company. If its early stage, then in the Lean Product Playbook's spirit:
-Problem-Solution Fit: Ensure it solves a real problem.
-MVP: It should deliver its core promise flawlessly.
-User Experience: Must be intuitive.
-Feedback Mechanism: Ready to capture user insights.
-Security: Non-negotiable.
Launch with a solid core, then iterate based on feedback.
Stability, new products are usually more buggy, so I think it's very important to keep it stable so that you can get valid information from your seed users
