Bilic was appointed as successor to Sam Allardyce this week and will lead West Ham into a new era as they play their last season at the Boleyn Ground before moving to the Olympic Stadium next year.
The Hammers had already signed goalkeeper Darren Randolph on a free transfer from Birmingham City before Bilic was appointed.
And they have followed that up with their first major signing of the summer by unveiling Spanish Under 21 international midfielder Pedro Obiang from Serie A side Sampdoria.
While the move has been welcomed by Hammers fans, there have been suggestions the club's hierarchy are already meddling in the new manager's transfer business given he took over less than 24 hours before and immediately went on a family holiday.
But Gold insists the former Besiktas boss has not been undermined and in fact gave the move for Obiang his seal of approval.
"No sooner has the ink dried on Slaven's contract and we have been able to announce our first major signing under the new manager," Gold told West Ham's official website.
"With Slaven's approval, action has been taken immediately to bring in another quality player and it goes to show the backroom mechanism that we have at West Ham.
"I certainly hope there are a few more signings to come."
Meddling in transfer business is a criticism that has been aimed at Gold and his fellow co-owner David Sullivan in the past with the likes of Diafra Sakho and Mauro Zarate signed by the owners rather than Allardyce last season.
The club brought in the highly regarded player recruitment guru Tony Henry last year.
It was an appointment that caused friction between the owners and Allardyce, who had his own man Martyn Glover heading up transfers.
Now in Bilic some fans fear the owners have simply appointed a 'yes' man who accepts the setup.
But if Gold's comments are to be believed perhaps it is only fair to praise the club for being proactive and bolstering the squad ahead of their early start to the season on July 2 and in doing so giving the new manager more options as and when he was appointed.
