Saxovent Smart Eco Investments GmbH is an owner-managed investment company based in Berlin, specializing in renewable energy project development and sustainability-focused finance. Founded in 1997 by Carsten Paatsch and partners, the firm has developed over 400 wind turbines across Europe, with projects in Germany, Eastern Europe, France, and the United States. These installations generate clean electricity for more than 900,000 people and prevent over one million tons of carbon dioxide emissions each year. Headquartered at Fritschestrasse, Saxovent operates through an independent power producer business and multiple subsidiaries.
The firm’s investment approach combines project development with venture funding, focusing on wind and solar energy, energy efficiency, and related infrastructure. Through its subsidiary WindPunx, Saxovent handles commercial and technical operations, while Powerbude manages land acquisition for renewable projects. Its venture arm supports early-stage companies in energy and agriculture, typically investing up to €500,000 in initial rounds with follow-on funding up to €2 million. Saxovent partners with established firms like Ironwood Projects in the U.S. and H2air in France to expand its project portfolio.
Saxovent integrates battery energy storage systems in its own wind and solar parks, ranging from local installations to grid-scale units. Its clean technology investments include participation in a seed round for hellgrün energie GmbH, which offers rooftop solar solutions, and co-investment in Deutsche Sanierungsberatung, a startup that combines home retrofits with solar PV and heat pumps. The firm has also pledged multi-million euro commitments to industrial solar deployments in Spain, working with Entoria Energy to provide tailored energy systems for small and mid-sized businesses. By blending project expertise with targeted equity stakes, Saxovent aims to support measurable carbon savings across its portfolio.
