Big Data start-up Quantexa has hired Karim Rajwani, former money laundering reporting officer and global head of financial intelligence at Deutsche Bank, as a global anti-money laundering (AML) advisor.

Rajwani joins as the London-based firm looks to broaden its service offering and attract international clients as part of its expansion overseas.

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 delighted to join Quantexa at a key point in their national and international expansion," Rajwani said.

"I'm impressed by their pioneering and revolutionary technology which is revolutionising Entity Resolution and Network Generation, and I am looking forward to bringing my expertise in AML and CTF to the team and thus additional value to our clients."

Prior to Deutsche Bank, Rajwani was global head of AML at Royal Bank of Canada, where was responsible for the roll out of the bank's AML monitoring systems, client and payment systems, sanctions policies, financial intelligence and analytics units.

He has over 35 years of finance, risk management and anti-financial crime experience including: anti-money laundering, anti-terrorist financing, sanctions and AML Compliance.

Quantexa chief executive Vishal Marria said: "Karim's vast experience in AML and CTF made him the ideal addition to the expertise and talent of the Quantexa team - in analytics, data science and machine learning, focused on financial crime.

"It is the perfect partnership in our eyes and through it, we’ll continue to deliver the best possible value to our customers."

In September, Quantexa appointed Nick Donofrio, former executive vice president of innovation and technology at IBM, as its new chairman.
