John Randles Takes the Lead at Siren

Subscribe to our newsletter

After leaving the post of CEO at Bloomberg PolarLake in August 2017, John Randles has emerged as CEO of Siren, a Dublin-based start-up dedicated to the development of a data intelligence platform that combines search, business intelligence, graphic and knowledge representation to advance how financial services firms, among others, address complex questions.

The company’s platform is based on semantic technologies and is designed to provide a unifying layer on top of big data infrastructure tools, such as Hadoop and Solr, and deliver search, semantic drill down, global joins and advanced graphing capabilities. Financial use cases include fraud detection, risk management, opportunity discovery and Know Your Customer (KYC).

Siren was founded in 2011 as a spin-off of the Data Intensive Infrastructure research group at the National University of Ireland Galway (NUIG). Search engine research at the university created the first generation Semantic Information Retrieval Engine (SIREn) and other techniques to index, understand and reuse 30 billion knowledge graphs created by crawling the ‘web of data’.

Siren is Randles’ third start-up having previously set up Eontec and PolarLake. Eontec was acquired by Siebel Systems, which was acquired by Oracle, and became the core of the Oracle financial services offer. PolarLake was acquired by Bloomberg and became the heart of the company’s data management utility. Siren, says Randles, has the potential to be ‘the biggest by far’.
