Young confirmed that much-needed investment in the club from an unnamed multi-millionaire was imminent after a consortium, led by Ken Moss, took over in September to stave off the threat of administration.
"There has been a lot of uncertainty off the field but I always had confidence that the people around the club would deliver and thankfully they've done that," said Young, whose side just escaped relegation last term.
"But it makes it a great deal easier when you are getting results on the pitch.
"We had belief that we would have a better squad this year but we have surpassed expectations.
"Last season was just about survival. This season was about making some big strides forward and we started gaining belief and momentum from some of our home performances.
"And then we needed to back that up with some big wins away from home and they don't get much tougher or harder than a place like this."
Wasps led 14-0 with tries from Tom Varndell and Christian Wade, but a try from Matt Hopper and Evans' boot trimmed the gap to one at the break. The visitors moved four ahead with a Nicky Robinson penalty before Nick Evans missed a penalty, scored one and missed another with two minutes to go as Wasps clung on.
On the first day of the season Evans struck a last-gasp penalty to see off Wasps 42-40 and Quins director of rugby Conor O'Shea acknowledged what goes around comes around.
"It's a disappointing loss as you want to win your home games but we gave them a 14-point lead at the start of the match and then you're chasing," he said. "We got the rub of the green at the start of the season and then we didn't get it here, but that just shows how close this league is."
