Our Team

Zeta Alpha is located at Startup Village on the Science Park campus of the University of Amsterdam. With strong ties to the local and global research community, we are motivated by building beautiful and useful products based on the latest AI and natural language understanding technologies. Zeta Alpha is not your typical startup. We are building a team and a company for a long-term prosperous and impactful future.

We have the ambition to change how AI helps people to make better decisions in their work, and the drive to create a new product category to realize this ambition.

Marzieh Fadaee

During her work as NLP Research Engineer at Zeta Alpha, and with her PhD in Computer Science at the University of Amsterdam on meaning representation in machine translation, Marzieh heads our R&D efforts. Her interests lie in getting insights from data and understanding natural language. When not training understanding models, she’s training her own brain to learn a new language.

Sergi Castella Sapé

With a BSc in Physics, and a Master's in AI, Sergi keeps the pulse for you on all new trends in AI.  He is a prolific blogger, the voice of Zeta Alpha on social media, and eager to read and explain as many cool AI papers as he can. A native of Barcelona, he is the most musical of the bunch, and has long good conversations with friends as a hobby.
