• The finals event was the culmination of the four-month clim@ scaler program and provided a platform for the seven green ventures who participated in the program to present their innovative climate action solutions to an audience of investors, industry experts, and energy specialists in Amsterdam

Luxembourg and Amsterdam, 21 November 2022 – The 2022 Clim@ Scaler program successfully concluded with over 70 guests taking part in the program’s final event in Amsterdam. In front of an audience of industry experts and investors, the program’s seven ventures presented their pioneering business models, their positive environmental impact, and their funding needs and expansion plans to continue their scaling journey. The audience heard from a diverse array of solutions and innovations in the areas of energy efficiency, circular economy, and sustainable energy. Clim@ was launched by the Green for Growth Fund (GGF) in 2018, and the third edition, Clim@ Scaler, was implemented in collaboration with Rockstart, a global early-stage investor.

The program’s seven ventures – Plug'n'Grow, Fusebox, Tagaddod, effa, Loggma, Fazla Gıda, and Wattnow – were selected from a pool of over 100 applicants and come from five countries. Across the four-month program they received in-depth mentorship, targeted technical training, and access to a wide network of industry experts and investors – all based on a tailored needs assessment of each business. Going forward, the GGF Technical Assistance Facility will continue to work with and support the program finalists on their journey to scale sustainable business models and impact.

GGF Chairman Christopher Knowles said: “The event was a great success and brought together like-minded individuals to hear from ventures across the green ecosystem contributing to the advancement of solutions to address and adapt to climate change. As a successful example, Clim@ Scaler has revealed the impact that can be achieved through platforms to scale innovative businesses and concepts that transform the way we are shaping the world for a sustainable future. Particular thanks go to Rockstart for their expertise and support throughout the program, and thanks as well to EU4Energy and the German Federal Ministry for Economic Cooperation and Development for their generous support.”

Rune Theill, CEO and Co-Founder, Rockstart stated: “Clim@ Scaler 2022 proved to be a successful and impactful platform in driving positive regional change. The final event celebrated the end of a fourth-month program led by GGF and designed and implemented by Rockstart. This year’s initiative supported the seven selected start-ups in preparing to scale their businesses, building long-term partnerships, and putting forward their unique solutions for climate change mitigation. We would like to thank GGF for their trust and partnership, and we look forward to collaborating in 2023.”
