The UK company is a customer analytics and business intelligence provider with eight years experience in the retail, finance and travel sectors.
David Smith, director at Site Intelligence, who set up the Sydney office said it has already had interest from the Australian market.
"There is huge potential for business in Australia to improve its online performance as well as its multichannel activity," he said.
"We saw this as a real opportunity for Site Intelligence and have had a fantastic initial response from an array of business sectors."
The company provides customer offline data such as in-store sales to let clients see their customers' and prospects' browsing and spending habits.
It then lets them tailor an offering to them to increase sales, conversion and retention rates.
Its services include Visitor Behaviour Information System (VBIS) which transforms business data into adaptable and actionable information.
Smith said VBIS enables businesses to gain the insight they need to profitably drive their business.
