Vireo Ventures is a Berlin-based early-stage venture capital firm dedicated to accelerating Europe’s transition to an all-electric future. The firm began as a small angel investor network built on the conviction that electrification is both the defining challenge and the greatest investment opportunity of this decade. Today, Vireo manages institutional capital and collaborates with major European energy players to back startups driving innovation in grid intelligence, heat decarbonization, and electric mobility infrastructure.
Vireo focuses on climate technology and energy transition solutions across Europe, particularly startups that support electrification.
Its sector priorities include grid optimisation, heat decarbonization, electric vehicle infrastructure, and other enabling technologies that strengthen Europe’s energy independence and competitiveness.
The firm emphasizes early-stage opportunities where technical innovation can be matched with industry partnerships to accelerate scaling.
In September 2025, Vireo Ventures announced the final close of its Electrification Fund I at €50 million, surpassing its original target. The fund is backed by a strong syndicate of strategic investors, including leading European energy companies Encevo, Verbund X, and EnBW New Ventures, as well as the European Investment Fund (EIF).
Electrification Fund I is designed to provide early-stage capital to startups addressing bottlenecks in Europe’s energy transition. Beyond financing, the fund leverages deep sector expertise from its limited partners, who actively collaborate with portfolio companies through pilot projects and scaling opportunities.
This hands-on, collaborative approach distinguishes Vireo from traditional venture funds by coupling financial backing with practical industry engagement.
Despite a challenging fundraising environment, the fund’s oversubscription reflects investor confidence in climate technology as a cornerstone of Europe’s future security and growth.
Leadership
The firm is led by Managing Partner Felix Krause, alongside a team of sector specialists including Investment Manager Lou Arzur. Krause emphasizes the strategic importance of grid investments for Europe’s long-term competitiveness, while Arzur has highlighted Vireo’s commitment to diversity, with one-third of the portfolio companies featuring at least one female founder. The leadership team brings direct experience in energy transition challenges, ensuring investments are evaluated with both technical precision and financial discipline.

Vireo Ventures pursues a high-conviction investment strategy, targeting startups where electrification technologies can scale rapidly with the right partnerships. The firm works closely with incumbents in the energy sector to de-risk adoption and accelerate market access.

Diversity and inclusion are also embedded in its approach, reflecting a commitment to reshaping the energy transition ecosystem for both resilience and equity.
