Are there any need for UX personalization to increase conversion rates?

I am trying to build an UX personalization platform - to increase sales & conversion rates for your store.

It will be a simple personalization API & Shopify App, where you can personalize the user experience based on their behavior.

Do you think is this something that people need?

Thanks, waiting for your replies.

If you wish to take an early look and provide feedback, please comment.
