Siena Secondary Fund, an investment fund founded in early 2021, which focuses on secondary market transactions in high-growth late-stage startups by providing liquidity to early investors, (ex-)employees and founders, made its new deal, acquiring a stake in Skeleton Technologies - a pioneering player in the field of energy storage solutions.

Skeleton Technologies is a Global Cleantech 100 company and a technology leader in fast charging for transportation, grid, automotive, and industrial applications - most well-known for its supercapacitors and SuperBattery energy storage solutions, which are based on patented curved graphene technology.


Skeleton has attracted over the history more than 200m EUR capital from Siemens, Marubeni, European Investment Bank, Taavet+Sten and several corporate investors and is considered to be one of the candidates for the next Estonian unicorn.

"As we move towards a more sustainable future, Skeleton Technologies' cutting-edge solutions will play a pivotal role in reshaping how we store and utilize energy. We are excited to be part of this journey," said Lauri Isotamm, General Partner of Siena Secondary Fund.

Siena Secondary Fund has raised funds from over 80 investors from successful old and new economy entrepreneurs across Europe and has acquired stakes in several well-known scale-ups such as Bolt, Testlio, Starship Technologies, Veriff, Kry, TransferGo, Printify and Booksy.
