Climate Change Leaders

We help the world’s leading businesses navigate the risks and opportunities of climate change.

We’re building the world’s best climate change platform to seamlessly support all of an organization’s climate-related efforts.

Simplifying Climate Change Complexity

Behind Manifest is a team of leading technology entrepreneurs, developers, climate change specialists, data scientists, actuaries, financial professionals, lawyers and engineers.

We came together to shine a light on climate-related risks and opportunities, and advance strategies for businesses to thrive as the economy moves towards net-zero.

Our Story

In 2009, Laura Zizzo founded a climate change-focused law firm knowing she wanted to dedicate her professional career to the climate crisis. Over the years, her practice evolved into a strategic consulting firm. She was joined by her brother Ryan in 2015 to create an interdisciplinary climate strategy firm, Mantle314, where engineers, lawyers, accountants and finance professionals help translate the impacts of climate for business.

Having supported the world’s leading businesses, we set our sights on a larger goal—to offer best-in-class climate guidance at scale utilizing technology—so that every business can become more resilient to climate-related risk and seize opportunities.

In 2020, Manifest was born when Laura Zizzo joined forces with technology entrepreneur Jeremy Greven to scale our reach and impact through software and focus on strategic climate services. At the same time our construction operations spun-off as Mantle Developments.

With Manifest’s single focus—to build the world’s best platform for navigating climate change—we continue on our mission to guide businesses on their path towards climate confidence.
