Interface Capital Research
Overview
Interface Capital is a pre-seed/seed venture fund founded in 2022 by Christian Reber and Niklas Jansen, based in Berlin, Germany. The fund is operator-led by two successful European entrepreneurs who bring deep product and scaling experience.
Christian Reber is the founder of Wunderlist (acquired by Microsoft), Pitch, and Superlist. He has invested in 100+ technology companies including Notion, Synthesia, Framer, Writer, and Lilium.
Niklas Jansen is the co-founder of Blinkist, the bite-sized learning service that reached 25M+ users. He previously worked as a consultant at KPMG.
Investment Thesis
Interface Capital invests in iconic technology companies at the earliest stages. Their philosophy is rooted in Essentialism — doing fewer things but doing them well. They prefer to partner with incredible founders at the very beginning of their journey, preferably as one of the first investors, rather than chasing hot deals.
As founders themselves, they aim to collaborate with other great founders, helping them lay the right foundations for building successful companies. They don't have the biggest army of analysts but bring hard-learned knowledge and experience from building multiple companies.
