300ppm

What they do

300ppm is the dedicated climate and sustainability investment vehicle of ARB Investment Partners, a German real estate private equity firm led by Henri de Bokay. Unlike typical software-focused VCs, 300ppm specializes in hard assets and infrastructure-heavy technologies. They bridge the valley of death for industrial climate solutions by financing the early stages of infrastructure deployment-specifically targeting companies that have proven technology but need capital to build their first commercial plants or scale operations.

What they look for

300ppm views decarbonization as an infrastructure development challenge. Their thesis is that reaching Net Zero requires deploying hardware and physical assets at an unprecedented scale. They explicitly target the deployment gap-the phase where climate hardware startups struggle to find capital because they are too capital-intensive for traditional VC but too early/risky for traditional infrastructure funds.
