AENU

What they do

Founded by serial entrepreneur brothers Fabian and Ferry Heilemann, AENU is an impact-driven venture capital firm focused on the energy transition and the carbon economy. The firm aims to rewrite the VC rulebook by proving that high financial returns and measurable environmental impact are not mutually exclusive, championing a model they call "Impact Capitalism." Originally launched in 2022 with an innovative evergreen structure, AENU pivoted to a traditional closed-end fund model in 2023 to better accommodate institutional LPs. This strategic shift culminated in the successful €170 million final close of AENU Fund I in September 2024.

What they look for

AENU invests in founders building climate and social impact technologies with intentional, measurable, and net-positive outcomes at a meaningful scale. Their core thesis revolves around the energy transition and the carbon economy, operating under the belief that solving the climate crisis presents the largest opportunity for entrepreneurial value creation in the 21st century.
