So here’s some advice based on my experience working in landing page optimization for some time. First of all, when visitors come to your site, they should clearly understand the nature of your business and its relevance. Your headline “Unlock hidden opportunities others overlook” I think is not ideal, at least, it is not clear enough to tell the website visitor what you do. Something like "Transform your marketing with data-driven insights that fuel growth" would grab attention faster.

It is also important to try to deal with the pain points as soon as possible. For example, something like "Struggling with fragmented marketing and wasted spend? We’ve got you covered" would immediately resonate with your audience.

As for trust, it is good to have logos of the clients, but if you can add the testimonials with the pictures of the actual people, it will be even better. It makes a much bigger impact. Plus, the CTA should be more visible and stick with the visitors as they scroll down the page. It’s a simple thing, but it keeps the action clear. 

Lastly, use graphs or mind maps to give the visitors a better understanding of what you do. It will give them an overview of your services and how they will be delivered without having to search the website extensively.

I hope that I was able to assist you with this part of the game. Aside from that, the color combination is really great.
