Big Data start-up Quantexa has announced Nick Donofrio, former executive vice president of innovation and technology at IBM, as its new chairman.

Donofrio will support the company’s ongoing strategy as it expands into international markets.

Quantexa, which raised $3.3 million in funding in March, enables organisations to make better decisions from their data.

Its revolutionary technology is based on the latest developments in Big Data software and uses real-time entity resolution with network analytics and AI to knit together vast and disparate data sets and derive actionable intelligence.

The company is headquartered in London, with offices in Brussels and Sydney.

“I am thrilled to be joining Quantexa at such an exciting time in their national and international growth,” said Donofrio, who was credited as a pioneer in technology innovation during 44 years at IBM.

“Their pioneering, revolutionary technology is quickly pushing them to the forefront of Entity Resolution and Network Generation and I am looking forward to working with the team as we continue to provide innovation and value to our clients.”

Donofrio serves on several company boards, notably Liberty Mutual and Bank of New York Mellon.

He is also a fellow of the Royal Academy of Engineering in the UK and was voted one of Business Week magazine’s 25 Top Innovation Champions.

Quantexa CEO Vishal Marria said: "The market demand for truly understanding customers, their relationships and applying advanced analytics continues to grow.

“Nick's unrivalled experience in building market-leading technologies will ensure that Quantexa meets that demand and continues to deliver the best possible value to our customers.

“He joins the Quantexa team at an exciting time as we expand into new markets, including the US.”
