Feedback on my website

Hello everyone,
I want to start a new project, a newsletter to be specific. But first I need feedback.

Here's a link to my website, product discovery: https://productdiscovery.carrd.co/

Can you share feedback on my website? I'd like feedback about:

• the design
• the copywriting?
• Does it sound a good idea?

If interested, feel free to subscribe :)
Cheers
