He is the co-founder of ThinkTank Maths, which provides consultation service and research in applied mathematics and business development. Rajaniemi has had a big impact on the field with only a relatively small body of work.

His most recent book is a collection, Hannu Rajaniemi: Collected Stories. Coming up is a new novel, Summerland.
