Warriors came up against another Sevens specialist side Samurai in their second match of the competition and eventually lost 26-12.
However, Mark Hewitt's men turned their fortunes around in their final two group games as they saw off Red Panda and Irish Exiles to progress to the Elite Plate competition.
In the semi-final Warriors cruised past Northumberland University 40-5 before defeating Red Panda 24-14 in the showpiece event.
Academy Manager Hewitt said: "After a tough start to the competition, the players responded brilliantly and raised the level.
"I was delighted to see them achieve success in the Plate Final and it was the perfect reward for their attitude and dedication throughout the competition."
