This has been posted a few times recently and certainly looks intriguing, but as far as we can tell, there only there-there is a signup list.

For a good HN thread, we should probably wait until the product is available—or at least for more information?

Edit: looks like there was some sort of earlier discussion at:

Melbourne startup launches 'biological computer' made of human brain cells - https://news.ycombinator.com/item?id=43261218 - March 2025 (37 comments)

The comments are pretty generic, which is the sort of thread we get in the absence of more significant information, so I think waiting is probably the right call. Disagreement is welcome though!
