Immediate thought was a pull-type amphibian.
But I've never seen any with the engine/prop so far forward. The Czech Mermaid is designed like that, but with metal hull and prop further aft than this one.
This looks like a brand new type, and being an old-timer I don't know these modern composite thingies too well. Ultralight?
As to the background clue - can only see some vintage crafts.
