Alpine Space Ventures, an industry player-led venture capital firm focused on early stage investments in the fast-growing European space sector, today announced the final close of its maiden fund totaling €170 million.
The fund is primarily targeting Series A rounds and will invest in startups that contribute to or leverage the global space industry to build an initial position, with a particular focus on hardware and software solutions for the industrialization of the space sector and connectivity and data. Alpine Space Ventures will focus on investing in the European ecosystem, but also have the geographic flexibility to invest in the US and elsewhere, leveraging the team’s industry relationships, notably with SpaceX’s early leadership team. A concentrated portfolio of 10-15 carefully selected investment targets will receive up to €5 million initially, reserving significant dry powder for follow-on rounds.
Fund established by industry players
Alpine Space Ventures’ investment team has over 50 years of experience building products, teams and companies while shaping the NewSpace industry. Founding Partner Bulent Altan was an early leader at SpaceX, joining Elon Musk’s team in 2004 to oversee avionics development for the Falcon 1, Falcon 9 and Dragon capsules, and later the development of the first Starlink satellites before leaving the company in 2017. Founding Partner Joram Voelklein has been successfully investing in technology since 2015, making an angel investment with Bulent in launch company Isar Aerospace, becoming one of the early backers of the European space tech ecosystem.
This expertise is further complemented by Alpine Space Ventures’ investor base, which is comprised of many entrepreneurs and space industry pioneers, including more than 20 early SpaceX employees.
Other investors in the fund include the European Investment Fund (EIF), the NATO Innovation Fund (NIF) and several prominent family offices.
