Poor conversion rate. how to make Neuronahealth.com landing page better

Hello everyone! I've loved seeing all the incredible work everyone has been doing. It's very exciting to be working on my first startup. One thing I've noticed is when visitors visit neuronahealth.com the rate of them signing up for our waitlist seems very low (4.6%). These are all via organic methods not paid ads or anything if that impacts anything. I'm not an expert in design by any stretch so any input would really be amazing.
