Congratulations on launch. I love the domain name BrandableNames.com. It is super cool. The website design is overall OK but it can be improved a lot.
The logo in hero section looks weird (or ugly to be precise) especially when you already have logo in navbar. I'd rather go for simple text/tagline something like A Marketplace for Brandable Domain Names (just an example) and a search box underneath.
Why images for USPs like memorable, unique etc? Why not just use icons like Font Awesome (fontawesome.com) or Feather SVG Icons (feathericons.com)? Images are visually disruptive and take more time to load (not good for SEO ranking). Icons are lightweight, beautiful and add visual-interest.
Also, you should improve website color scheme. Instead of using both dark colors, I'd rather use one dark and one light color to create color contrast. Bright colors always attract more attention, especially against dark. Use them sparingly to highlight the important parts of your design.
At the end, your website logo is completely outdated. Com'on, you own such a good domain name, spend some bucks to hire a good designer and get a new logo. Don't forget, your logo is your brand identity too. It should be unique, memorable and make a lasting impression.
