Starting from the top of the page - the navbar has too much top padding which unnecessarily pushes the page content down.
The goal of hamburger menus is to reduce the space that navbar items take up on the page. That's why they're supposed to be used on mobile devices. On desktop, where there's enough space, they only make it harder for users to easily navigate to other pages. So, I'd recommend you don't use it.
There's quite a lot of text in the hero section, yet the message is not clear or convincing.
You need to first help visitors understand how your product will solve their challenges, overcome their objections, and build trust, before asking them to commit to signing up.
Also, if you offer a free trial, why would they buy if they can test the tool for free? I'd recommend replacing the 'Purchase' button with a product demo offer. This way, you'll not only be able to explain your product 1-on-1 but also gather some invaluable insights you wouldn't get without direct interaction.
Another thing that's missing is the duration of the trial.
The layout of the hero section looks a bit messy and could also be improved. The video should be moved to the right, so it doesn't push the subheadline down. This way, you'll be able to reduce the gap between the headline and subheadline. This will make it look cleaner.
The goal of the homepage (aside from explaining why your product is a good fit for your audience) is to drive traffic down the funnel. By pulling users away from the main goal - signing up - you're causing some of this traffic to get distracted.

"By getting your data stories read, we can get your insights actioned" - same comment as above - why should users care?
