Bistech co-owners, Shane Morgan, Justin Hoareau and Brad Culbert join Deloitte's analytics and cognitive consulting practice in leadership positions, with Culbert becoming a partner in the firm.
Bistech's 17 experienced consultants will start working from Deloitte's Eagle Street, Brisbane offices from the beginning of April.
"As clients increasingly explore shifting their data capabilities to the cloud, businesses are at a tipping point as they adopt more holistic data strategies," said Deloitte CEO Richard Deutsch.
"Australia's data analytics market is expected to deliver the fourth fastest growth rate in Asia-Pacific behind China, Indonesia, and India – so the timing is right for Deloitte to welcome Bistech's significant capability and experience to our data modernisation practice."
Deloitte Consulting managing partner Kaylene O'Brien said "The Bistech team bring a great mix of business and technical expertise that is increasingly in demand from clients seeking to extract maximum benefit from their data.
"Their service offerings closely align with client demand, including data architecture, cloud data solutions migration, data asset modernisation, predictive analytics and machine learning."
Morgan noted that Deloitte has the same people values and customer focus as Bistech, while Horeau suggested the change would not affect the delivery of "quality professional services and genuine value to our customers."
Culbert said "There is a growing demand for multi-technology solutions that drive higher business impact by leveraging data.
"Together with Deloitte, we are excited to lead the way towards these modern business solutions and continue guiding clients to success."
The terms of the transaction were not disclosed.
