A Global Program Scaling Climate Tech Startups

At ClimateHaven – A climate innovation hub created by Yale University and Connecticut Innovations

Our Kaplak ReGen Accelerator at ClimateHaven is THE growth opportunity for early-stage startups working to decarbonize at scale across five sectors: Energy, Real Estate, Food, Transportation, and Health.

During our two-month programs, we take up to 10 companies on a deep dive into the ‘Dreams & Details’ framework: a proven leadership and strategy method developed and used by senior executives to accelerate decarbonization at some of the largest organizations in the world, including Maersk, FLSmidth, and Energinet. This framework, plus our advisory services, help participants the jump from founder to CEO, and provide a blueprint for their ‘stakeholder story’ and strategy.

We also provide our founders with access to capital, customer introductions, and a world-class mentor network.

And the journey doesn’t end at Demo Day. Upon graduation, companies are assigned one of our ‘Kaplaks: global business leaders who support your growth with their subject matter expertise, leadership experience, and connectivity to their global networks.

Decarbonizing the global economy is the greatest opportunity of our time. We believe that with a proven leadership model and a powerful network of support, we can launch the next generation of breakthrough companies.

What our founders think

How the 'Dreams & Details' framework has been used at scale

The ‘Dreams & Details’ strategy framework, created by Jim Hagemann Snabe (former Chairman, Maersk; Chair, Siemens & Northvolt) and Mikael Trolle (former Danish National Volleyball Coach), provides the tools, as well as a unique ‘Strategy Map’, for our founders to outline their ambitious dream and identify the crucial details required to realize that dream.

We were inspired to adapt our strategy framework for startups and scaleups in the wake of our founding partner Jim Hagemann Snabe’s time as Chair of Maersk. There, he used ‘Dreams and Details’ as a blueprint for accelerating a massive decarbonization transition, with a plan to launch 8 container vessels running on carbon neutral methanol by 2024 and become carbon neutral by 2040. The first such vessel, the ‘Laura Maersk’, powered by green methanol, pulled into port in Copenhagen on September 14th, 2023.
