Abstract The fintech ecosystem is a highly dynamic environment. Venture investment in fintech grew by 11% to $17.4 billion in 2016 according to Forbes and Pitchbook . Having a clear picture of this ecosystem at a given point in time is much needed to inform policy activities as evidenced by the European Commission call for tenders SMART 2016/0042. This paper describes our approach to integrating, enriching and presenting data about the fintech ecosystem. It presents FintechBrowser , a demonstrator of an integrated set of dashboards and a graph explorative-browsing tool. 2. Introduction Over the past decade we have witnessed technology-driven innovations that disrupted the financial services industry and continue to do so. In consumer payments, nascent start-ups are able to bring to market affordable and flexible cross-border payment solutions outperforming some of the largest traditional financial institutions. In the funding space, the rise of crowd-funding democratised access-to- capital creating a whole new market segment. In investment management, robo-advisors renewed the faith of many in the applications of Artificial Agents while providing satisfying results at competitive costs. Disruption caught-up even with currencies - one of the oldest concepts in the financial industry - with the proliferation of crypto-currencies using blockchain technologies. Having a clear picture of this ecosystem at a given point in time is much needed to inform policy activities as evidenced by the European Commission call for tenders SMART 2016/0042. Our research is focussed on exploring the fintech ecosystem using ontological modelling. It seeks, inter alia, to improve our understanding of this ecosystem, which is a critically important environment from which solutions to operational risks at financial institutions frequently arise. We combine novel knowledge
