It's immediately obvious to me that the illustrations are AI slop
You should invest 20 bucks into getting some pictures of a guy in a datacenter, or 200 to pay some dude on Fiverr to draw you some sinks, instead of having these be the first thing customers see when checking out your product
They care much more about whether this product solves a problem they have.
This is based on my 17 years of running first a successful B2C product then a successful B2B SaaS.
Minor changes to one's home page tend to have little observable change in numbers of trial signups, the rate of conversion to paid customer, and so on.
Maybe, but in a conversation about acquiring your first hundred users; you don't have a lot of word-of-mouth backing up the quality of your product. Your ability to effectively present your product will never be more important.
If it's important enough that your brochure website has images on it at all, then it's also important enough for them to not look like something you'd see slapped on a scam.
Might be soulless and ugly too, but at least it doesn't make your customer think "Hold on is this a scam?"
His website seems fine to me.
I don't believe this qualifies as AI Slop. They are all consistent in their style and thus 'on brand' for what they are trying to convey. While visuals are fairly subjective and these may not speak to you, they don't have 'obvious slop characteristics' eg 6 fingers or 3 eyes imho.
