Backing pioneering Washington founders inventing climate solutions while driving local resilience and global impact.
Launched by VertueLab, Opalene Climate Capital is an uncommon venture capital fund that doubles private investment with state-matched dollars to accelerate clean tech innovation and impact.
The fund focuses on Washington state, home to one of the world’s most vibrant climate tech ecosystems.
We Invest In
We invest in scalable hardware, software, and AI-enabled clean tech startups with potential for global reach in the energy, mobility, built environment, agriculture, maritime, industrial, and aviation sectors. Opalene centers growth and impact at the Seed and Series A stages with a focus on:
CLIMATE RESILIENCE
Innovation that helps communities withstand the stresses of climate change on our infrastructure, health, natural ecosystems, and economies.
OVERLOOKED VENTURES
WA- based climate tech startups, including visionary founders and teams historically excluded from venture capital.
CLIMATE MITIGATION
Reduction, prevention, or removal of greenhouse gas emissions, to minimize damage and repair our climate.
Opalene sprouted in one of the nation’s most ambitious hubs for climate innovation — Washington state.
With a nearly $1 trillion economy, deep technical and talent, and a suite of supportive climate policies, the region offers fertile ground for breakthrough solutions and scalable ventures.
The climate crisis won’t wait – and neither can we. Now is the time for funders and innovators to act.
