Those 'clones' are a bit more than I thought they'd be - if the budget stretches a bit it's worth considering the MX Keys from Logitech which are about £100ish. Mine's been great for the couple of years I've had it and it fits in okay with the Mac aesthetic (they do an MX Keys Mini now too).
..to answer my own question, it's Matias!
They do such nice things as a tenkeyless variant..
..alas only in US or "Nordic" layout, I now realize ☹️
