I'm imagining it has to do with the way designers work. They generally have stakeholders moodboard (basically creating a pinterest board with inspiration from different brands), and then they create a similar "feeling".
As humans, we're kind of evolved to recognize patterns, so when we start seeing the same branding art direction it stands out to us and we may try to conflate some deeper meaning to it. But in reality, it's just a few brands that share the same branding art direction probably because some execs liked the way it looked and felt and asked their designers to do something similar.
At least for me the net emotional effect of the "For Desigers & Developers" section of the homepage was a strong impulse to bounce. (I'm in the target market.) Ultimately for the sake of research I clicked through to the ~/product page, where I found the diagrammatic graphics much more compelling.
I'm working on a product in a similar space, and struggling with the question for our own marketing materials. Amy Hoy's material [1] on audience "worldviews" has been helpful so far. (No personal affiliation.)
Best of luck with your launch!
This style of pastel colors, wavy svg graphics, and happy avatars seems super popular right now [1] [2] [3]. I'm curious if it has a name and where it originated from (if anywhere?)
Overall I like the aesthetic quite a bit, but it's such a distinctive look. I'm surprised I keep seeing it crop up nearly copy+pasted between all of these companies
