He said: "I'm really happy to receive the award and it means a lot. The competition was all about how we came through as a team. We had a good mix of experience and young talent and it worked well for us."
After leaving the JP Morgan Sevens empty-handed last season, Warriors showed a renewed winning mentality on Thursday and impressed on their first outing since the arrival of Dean Ryan.
And De Carpentier admits his side had targeted three wins before the competition even began.
He continued: "We said earlier in the week that we were targeting three wins so we were happy to come away with them.
"We were training hard leading up to the competition and we came out of the blocks flying. It's important to get a good start in games so there are a lot of positives to take."
Warriors will travel to Bath's Recreation Ground next Friday for the final and De Carpentier is hoping to surprise a few more people when the action gets underway.
He added: "We're all looking forward to the final and we'll go there looking to pick-up from where we left off.
"The level will be raised again and we'll be doing all we can to get some good results."
