Amusingly, the DeSol web site has a copyright date of 2023 on it. I sent them a message asking if the product existed yet. They sent back, from a GMail account, "Who are you". I replied that I'd signed my message with my name and sent it from my own domain, what more did they want? Asked "You're sending from GMail, who are you?" Got back "(HN does not do Unicode emoji)". So, not sure what to think of that outfit. They seem to have a good sense of aesthetics; no idea if they can make it work.
