Not a single screenshot on the homepage? The number zeroth thing I want to see is a picture of the thing. Maybe even a gif or a silent autoplay video. I saw there's a video but it's a guy who's gonna talk. I just want to see the product.
I believe 0:19 would make for a better thumbnail than the current. Shows the video is actually a product demo and not fluff from a talking head
As far as a screenshot for product? Not sure, it really stays out of the way which I like but that makes it difficult to convey visually. Which you seem to have realized :)
Funny thing is, this is a pairing app. It's actually better if it gets out of the way. But I agree, that thumbnail with both screen and speaker would be better. I think something with more on content on screen than just a dropdown from the contact list would look better. Either code or that fancy network monitor (plus the speaker).
I didn't even realize there was a video, but I certainly wouldn't have watched it, that's just not super thoughtful design, and the thumbnail kind of looks like a chatbot sort of thing, which in 2021 is something I ignore like banner ads.
I realize that watching a video is maybe how a lot of product companies wish potential customers made decisions, but much like an elevator pitch, if I can't scroll the website and have a glance at what the product looks like, I ain't gunna watch a vidya bud.
