Need feedback on product/landing page

Hey Founders,
I am developing new advertising platform called Murmur to help founders advertise smart and acquire more users.
Murmur`s marketing solution brings a whole new meaning to the word ‘data-driven’. It gives startups the power to target their brand messages on streets through the murmur intelligent billboard on wheels and seamlessly collect real-time data from these interactions in order to retarget viewers with online ads.
Need you feedback on my product and landing page: https://murmurcars.com

I started Murmur because while bootstrapping my first startup, and spending over $5K on facebook, google ads and getting $0 sales and found that my competitors basically pay higher price and target my audience as well.
I got so pissed off and was ready to shut down product but thankfully my wife gave me idea to advertise on billboards. But unfortunately almost all billboard companies are super expensive, do not give you any reporting, data which you can use for retargeting purposes.

I decided to fix it and this is the reason my i am so exited.

Murmur was internal product which helped us to bootstrap first startup from $0 to $150k in MRR.

I posted my experience in one of SaaS facebook groups and 250 founders reached me out and wanted to use Murmur.

This gave me inspiration to dedicate more time on Murmur.
