Brown was appointed as Town head coach last week, taking charge of a team that survived League One relegation on goal difference.
Pilley told The Gazette: “We have to improve, there are going to be a lot of meetings. I’m a firm believer that you have to let managers manage but, with that said, we also need to brainstorm.
“With the funds that Scott will have, I do want to have some input and I do want to give my opinion.
“I’m not going to say, ‘No, you can’t sign him, you have to sign him’. That would be overstepping the mark but I do think I can add value.
“We have some really good people at the football club and I think their opinion is hugely valuable. We’ve got to get the recruitment right. We have to get value for money.
“I had dinner with Scott and Steven Whittaker (assistant head coach) and we’re in a situation where Scott’s phone has been ringing already and there are very good players saying they want to be a part of a Scott Brown team.
“If that means we can get good players to help us on our quest to finish as high as we possibly can – to get that top 10 or play-off spot – then that is music to my ears.”
