Company Introduction

ISIN2LEI.eu is a RegTech start-up founded in 2018 by Johan Hol.
We went officially live on September 1st, 2018 and provide linked open data on Legal Entity Identifiers (LEIs) and International Securities Identification Numbers (ISINs).

Johan is working in the financial sector for over 10 years. He worked at BNY Mellon on regulatory reporting for pension funds and insurance companies. He started his own business in 2015 with key focus on data management and regulatory reporting.

ISIN2LEI.eu makes data available in a user-friendly webportal, where you can easily search and drilldown to the details. Data can be exported to CSV and PDF and you can create your own list of favorite LEIs and ISINs. Next to that we have an API and Excel AddIn which can be integrated in clients' systems and processes.

Regulatory Technology

Regulatory Technology

Regulatory technology, in short RegTech, is a new field within the financial technology industry that utilizes information technology to enhance regulatory processes. It puts a particular emphasis on regulatory monitoring, reporting and compliance and is thus benefiting the finance industry.

The objective of RegTech is to enhance transparency as well as consistency and to standardize regulatory processes, to deliver sound interpretations of ambiguous regulations and thus to provide higher levels of quality at lower cost. (source: Wikipedia)

ISIN2LEI.eu focuses on the main objectives of RegTech:
- Transparency
- Consistency
- High level data at low cost

ISIN2LEI.eu is being recognized by the industry as a leading RegTech firm. We were nominated for the 2020 RegTech Insight Awards in 4 categories and are included in the RegTech Supplier Guide amongst 92 other RegTech companies from all over the world.
