The striker or winger, 19, has joined from Ryman Southern League side Dulwich Hamlet and has been handed a deal until the end of the 2013/14 season.
"He's a young lad that was recommended to us and has trained with us for the last couple of weeks," Hull manager Steve Bruce told the club's official website.
"He's done so well that we've given him a pro contract for this season and next. He's one of those that is refreshing to see.
"He's been a breath of fresh air and who knows, we might just have unearthed a little gem."
The youngster turned in a couple of impressive displays for the Tigers' reserve side while on trial and will now work with coach Stephen Clemence in the development squad.
