About Us

We are ex-scientists, data specialists and world improvers, ready to amplify your impact.
Nicolas and Felix

We believe that the value we create for our customers is directly related to understanding:

That is why everyone at Seita works hard to understand the business case of our customers, understand a broad range of novel data science technologies and understand software development as a craftsmanship, with all the sweat and the pride that come with it.

We are ex-scientists (a spin-off of the Centrum Wiskunde en Informatica or “CWI”), and we collected many years of experience in the software and energy industries.


Nicolas Höning

Nicolas is an IT specialist who has spent his career to almost equal parts in academia and commercial web development. He holds a bachelor’s degree in Cognitive Sciences from the University of Osnabrück (Germany), a master’s degree in Artificial Intelligence from the Vrije Universiteit Amsterdam and in 2016 he defended his Phd dissertation in Computer Science at TU Delft (topic: flexible planning in smart grids) . Nicolas has been a programmer and data scientist in two IT startups, enabling neurosience-based web design and energy trading services. He also co-created a new data backend for an established company, which was cloud-based and required very high (99.9999%) availability. He lives with his family in Amsterdam-Noord and enjoys practicing his handstand.

Felix Claessen

Felix is a physicist specialised in energy science. After 5 years at Centrum Wiskunde & Informatica (CWI), where he designed and analysed market mechanisms for smart energy systems, Felix founded Seita in 2016 as a CWI spin-off. His vision was to match sound academic solutions to sustainability challenges. He is a former design team member and currently ambassador for the USEF foundation, which provides an international common standard for smart energy systems. In his spare time Felix enjoys documentary films which have shaped and continue to shape his views on systemic sustainability.

Talent is key

The value created by Seita is a direct result from the experience and insights of the involved minds. Getting the right talent to work on our customer’s projects is therefore our most important task. We are continuously working to find the best co-owners, freelancers, consultants and advisory board members who fit our way of thinking and like our idea of amplifying impact.
