If you are following pure Scrum then Sprint Review can help you. Only sprint review is the event of Scrum when Increment (developed software/feature) is ready for stakeholder review and stakeholders all allowed in this meeting.

Sprint Review:

A Sprint Review is held at the end of the Sprint to inspect the Increment and adapt the Product Backlog if needed. During the Sprint Review, the Scrum Team and stakeholders collaborate about what was done in the Sprint. Based on that and any changes to the Product Backlog during the Sprint, attendees collaborate on the next things that could be done to optimize value. This is an informal meeting, not a status meeting, and the presentation of the Increment is intended to elicit feedback and foster collaboration.
