Overcoming the launch fear

Hello indiehacker communinty.

TL:DR - struggling with launching my new platform stook.app

Stook is a platform to help founders, owners, and salespeople with storytelling.
On Stook, they can collect the information, create the story, measure it, and share it with designers, team members, and investors.

Feels the platform is ready for testing, but something is not working, i feel the flow, the UX/UI
My fear is that I will burn through my wait list and never hear from them again.

How did you get your first few clients?
Feel free to check the landing page https://stook.app

Thank you for the help
