Monstera lechleriana

Full disclosure - we think this is a Monstera...

But it's still in it's juvenile form. It may fenestrate (get holes in the leaves) as it ages in which case, yay! Sometimes trying to match plants can be tricky so we think we've identified it but even we haven't got it 100% right this is still a pretty gorgeous looking plant so you'll be winning even if we lost the identification battle.
