Founded in 2021 and headquartered near Munich, with additional operations in Oslo, the company combines deep expertise in battery technology and energy markets with a strong sense of purpose: driving meaningful change toward a sustainable world.

Its portfolio includes more than 200 MW of operating projects, 500 MW under construction, and an active pipeline exceeding 25 GWh, representing around 20% of the German BESS market.
In February 2024, it was announced that Brookfield-owned renewables developer X-ELIO and London-based private equity firm Nature Infrastructure Capital would invest in ECO STOR. Joining the management team on the capital table, this strategic partnership will provide capital and expertise to drive ECO STOR’s continued growth and diversification.
Combining technology, sustainability and a people-centred culture, ECO STOR offers an agile, mission-driven environment where innovation and integrity go hand in hand.

Om Papillon Executive Search AS
A Papillon Executive Search advisor is required to have extensive experience in the recruitment industry. It is essential for us to focus on the future of executive search—both by driving innovation within a traditionally conservative sector and, most importantly, by working with industries and companies we are truly passionate about.
Papillon Executive Search is committed to establishing a leading position in recruitment within two key areas, guided by our expertise and professional focus. We find it highly stimulating and rewarding to work within the green transition, technology companies, and start-ups transitioning into scale-ups, as well as scale-ups that have progressed further. These companies share a common thread: strong passion, ambition, and a clear vision for the future.
We believe we can add significant value by leveraging our expertise and acting as trusted advisors to our clients. Across industries, many of the challenges companies face are universal and not always immediately apparent—particularly when it comes to identifying and attracting the right talent for key positions.
We have identified two primary industry sectors where we will focus our efforts:
1. The Green Transition
The world is undergoing a major shift toward sustainability, and Norway has taken a leading role in many areas. With our background, experience, and network, we are well positioned to be a strong partner and advisor in recruitment within this sector. We are already working with companies such as Arendals Fossekompani, UMOE Gruppen, Å Invest, NRP Zero, Hydrogen Pro and Air Liquide, both directly and through their portfolio companies.
2. Technology Companies
This sector has many intersecting dimensions with the green transition and represents a broad yet clearly defined focus area. The phases, challenges, and dynamics that tech companies face are often similar. Our expertise extends to companies specializing in security, health, and welfare technology—sectors that contribute to a greater purpose.
Finding the right candidate requires a deep understanding of the business case, the company, and its current and future landscape. It also demands strong advisory capabilities, strategic insight, and—most importantly—the ability to attract the right talent with the right motivation for the role.
That is where we excel.
Our vision is that our contribution to the recruitment process will result in hires that positively impact the company’s working environment, productivity and profitability in the short and long term.
