The 33-year-old stormed to the top of the podium on Sunday, with Championship challengers Fernando Alonso and Sebastian Vettel finishing second and third respectively.
"The most important thing is to show everybody that Lotus is serious," Boullier told Autosport. "We have shown that we can deliver regular podiums, and we can now say we can win as well.
"Our strategy is that we want to be a top team, I always said this, and to be a top team we need to keep pushing and keep gaining more results, more resources and more sponsors to establish ourselves."
Raikkonen's win was his first Grand Prix pole since returning to the sport from a two-year hiatus.
