Redstone Blue is the dedicated ocean-tech and blue economy investment strategy of Redstone, a multi-strategy European venture capital firm founded in 2014. Based in Turku, Finland, Redstone Blue invests in early-stage startups building technology across sustainable maritime and port systems, ocean infrastructure and clean energy, marine intelligence, and blue biotechnology and water innovation.
Redstone Blue backs early-stage companies transforming ocean industries through innovation that supports more sustainable growth across maritime sectors, investing from pre-seed through Series A.
The strategy targets four areas: sustainable maritime and port technology (digitalized port operations, low-emission vessels, autonomous shipping, smart logistics); ocean infrastructure and clean energy (offshore wind, wave and tidal power, marine infrastructure); marine intelligence (AI-driven ocean data platforms, robotics, autonomous underwater vehicles, satellite monitoring); and blue biotechnology and water innovation (marine biomaterials, algae-based products, water purification).
The fund is explicitly Baltic Sea-first in its initial focus, leveraging the Nordics' maritime expertise and Redstone's broader European network of universities, research institutes, and industry players.
Redstone Blue announced a first close of $29M in August 2026, part of Redstone's broader blue economy strategy launched in 2025.
Investors include the City of Turku, Meriaura Invest, LähiTapiola, Aboa Advest, Kelonia, Adamo Capital, Rausanne, Henrik Paasikivi, Magnus Kihlgren, and ARGOng Investment AG, alongside angel investors, family offices, foundations, and other maritime-industry corporations.
Redstone is opening a new office in Turku, Finland to lead the fund. Initial ticket size is $230K to $2.3M, spanning pre-seed through Series A.
