I've just launched a productized service, honest feedback would be much appreciated.

Overall, its a great landing page.

Done well:

1. Clear CTA and value prop.
2. I like the app like icons in the Validate your idea section but consider using vibrancy of the background in other parts of your site and maybe opening up the icons to differentiate the section.
3. I love the glow behind the hero image.

Could be improved:

1. size of the hero image took awhile to load. reduce size.
2. "Our designers have worked with:" heading has poor legibility and the section just floats with a large inconsistent margin.
3. I lose the dark icons on the dark backround. improve the contrast.
4. Improve readibility in the FAQ by reducing the line length. Make the section thinner.

Look to https://github.com/home for inspiration (if you haven't already). There could be potential for opening up the Recent Projects section with a white background.

Hi Luka,

What's done well on the landing page:

1. The headline is benefit oriented. It clearly states the potential outcome.
2. Hierarchy in typography. It makes it easier for the visitor to skim the copy.
3. Big brand logos drive trust in the service and helps justify the price.
4. Colorful visuals aligned with the brand.
5. FAQ section answers a lot of doubts.

What needs to be tested / improved:

1. The headline highlights an important quality of the service i.e. ( interactivity ). It is not justified on the landing page. The featured hero image is static. It's easier to understand the hero image for a developer / designer but it does not communicate well with the target audience. A short animation of an interactive prototype synced on laptop / mobile can be a good substitution.
2. The benefits section after the logos can do better with a header. It will help the visitor understand the context of the content.
3. The recent projects section does not have a real and interactive prototype. The Klues app link takes to the product landing page. Add some real and interactive prototypes to ease the decision making for the visitor.

Hope this helps, Good luck.
