"Unfortunately, there is no method for The Seed Scout to confirm a donor’s medical history for accuracy."
Did you see this bit, OP? That would be a red flag for me.
I also can't see anything on their website about proper medical screening of the donor, or screening the sperm for hereditary diseases. It basically just says if you want that you have to arrange it yourself.
It's a massive risk.
They also contradict themselves as another page of their website they are complaining about sperm banks, and they say "Perhaps most heartbreakingly, there is no requirement to share serious genetic medical diagnoses with any children that are born using the donor sperm. This has led to many issues where families lack basic medical history information that could have allowed them to help their children...."
They don't do this either! And nor do they do any other kind of medical screening that they speak of.
I can't see how they are any better than a sperm bank other than you get to meet the donor a couple of times. They say they limit the families but how are they enforcing this - a donor could be donating to several places like this.
It just doesn't look like they are well regulated, and they are charging through the nose for it. Personally I think it looks like a bit of a con and a rip off, playing on people's emotions around the risks of using donor sperm.
I'd avoid them if I were you and use a reputable sperm bank.
