Our ambition is to play a central role in further development of the Dutch life sciences sector. We pursue that ambition by promoting innovation, knowledge valorization, investment and partnerships, particularly in the (bio-) pharmaceutical and green (biotech) sectors.

With those aims to the fore, we organize conferences, workshops and match-making events. We have an extensive network within the international life sciences sector and more than twenty years' experience, which we draw on to advance the goals of each event we organise.

At the point where an ordinary agency's contribution ends, our role is only just beginning. We seed partnerships to accelerate innovation and valorization. Our expertise is in the field of scoping, initiating and realizing cross-sectoral innovation. We catalyze the formation consortiums of innovative enterprises focused on the development of new products, services and markets.

In short, Iventus is a key contributor to advancement of the Dutch life sciences sector.

Rest assured
We provide a turnkey service that covers every aspect of event development and organization. And we have the insight, product knowledge and management skills to deliver consistently successful events, carefully tailored to your needs and objectives. As well as providing events for clients, we act as hosts in our own right. That generates expertise that is then at our clients' disposal.

Our dynamic professional team is characterized by its flexibility, commitment, efficiency and quality. From our origins on Leiden's Bio Science Park, we have built up considerable expertise and an extensive network in the life sciences sector, especially the agricultural, horticultural and pharmaceuticals industries.


Iventus founded by Leon Mur and Miranda de Regt in 2006.

Miranda de Regt
Miranda de Regt (1973) has been an independent entrepreneur since 1994. For ten years she owned and managed SOS Secretarial Office Support. She sold that business in order to specialize in the development of conference concepts and the organization of business meetings. After two years, freelancing for clients such as Bio Partner Center Leiden, Competence Centre Life Sciences and Leiden Bio Science Park, she co-founded Iventus. Miranda is a true all-rounder. With considerable experience in various industries and an extensive national network, she has the ability to bring together people with wide-ranging objectives. She has contacts throughout the secretariats of various industries and experience in organizing all kinds of events. Whatever the service and administrative support required, clients can therefore depend on Miranda and her team to deliver.
