Get to know us a bit better

Creativity is intelligence having fun - Albert Einstein

Keisan ® was founded in February 2015 by Jillur Quddus, a computational mathematician, with the goal of applying advanced analytics to vast volumes of data in order to solve real-world social, economic and geo-political problems. We are a specialised consultancy providing world-class expertise in Data Intelligence, Platform Engineering and Bespoke Application Development. Most importantly, we passionately believe in our 6 core values - Collaboration, Innovation, Imagination, Simplicity, Education and Dedication - whilst delivering real business outcomes to our clients.


温故知新 Learning from the past to understand the future

The name Keisan ® (pronounced 'K-San') comes from the Japanese word 計算 of the same pronunciation, meaning to compute or to calculate. Before Keisan ® was founded, Jillur worked across the world on the design and development of some of the most high-profile and cutting-edge analytical and data-driven technology solutions aimed at combatting serious organised crime, financial crime, fraud and cyber-crime. This included many years spent working in Japan, New Zealand, Singapore, Malaysia, Hong Kong and the UK. Many of the themes found in Keisan ® are inspired by the Japanese language, including Ramus Mori 森, Bonsai 盆栽, Kodama 木霊 and of course our company name Keisan 計算!
