James Dale has been appointed to the role of director of production and projects, while Oksana Koval takes up the position of director of operations and projects.
Dale and Koval will focus on the operational running of the company, with founders of SSG Create, Roger Smith and Ross McGinn, remaining as joint managing directors.
The new acquisitions are part of SSG Create's plans to expand into international markets, including the US and South America, within the next year, in addition to adding more staff throughout the company.
As well as this, the agency officially launched its new website alongside the move into new, larger offices situated near London's Tower Bridge.
SSG Create's joint managing director Ross McGinn said: "This is a new chapter for SSG Create and we are delighted to unveil both a new website and our new Tower Bridge premises.
"With an increasing global client portfolio, we felt we needed a website that reflected our full brand experience capabilities."
In March, SSG Create delivered a product launch for HTC at Olympia London for more than 900 delegates, which included a main theatre with hosted talks from a range of speakers and a dedicated space for delegates to test out the new phone.
