Christian Buchenau co-founded Paua Ventures in 2010, making him one of the firm's original builders rather than someone who joined later, and he has backed a wide range of companies including Outfunnel, Keelvar, Detectify, Tylko, PartsCloud, Retorio, and Carbon One, covering everything from sales software to furniture commerce to industrial supply chains. He aims to be the first institutional investor in the companies he backs, prioritizes how efficiently founders grow relative to their spending, and brings a pan-European perspective shaped by studying business in Vienna, Cologne, and Barcelona.
