The story so far

In 2020, Laura Zizzo, a climate change pioneer known for integrated legal and consulting leadership, joined forces with proven technology entrepreneur Jeremy Greven to create Manifest Climate. Their goal was to scale the reach and impact of the strategic climate services delivered by the consulting business Laura founded in 2015.

Today, Manifest Climate's global climate change solutions combine software with strategic climate services. Manifest’s technology uses an AI-led approach to help surface insights about how businesses are managing climate risk, both for their own insights and as part of ever-increasing disclosure regulations around the world.

OMERS Ventures first invested in the company in 2021. Today, customers of Manifest Climate include some of the world’s best known financial institutions.
