Brighteye Ventures 
PT1 Ventures Overview
Proptly was founded in 2021 by Kristoffer Gjerde, Gunnar Windsand Sem, and Thomas Kristiansen, with a bold vision to transform the often-overlooked, yet critical, part of the climate tech ecosystem: installations. What started as a casual conversation over Christmas drinks about the headaches of managing contractors, quickly turned into a mission to streamline the installation process for climate tech solutions across Europe.
