International Climate Finance Accelerator
A public-private partnership created in May 2018 by Luxembourg's Ministry of Finance, Ministry of the Environment, and twelve private financial sector entities. The ICFA supports emerging fund managers focused on innovative climate finance investment strategies, providing coaching, training, and financial support to help them reach scale. It selects cohorts annually and expanded in 2024 to also include a parallel International Social Finance Accelerator track.
Lightrock
Lightrock is an impact-focused growth equity platform backed by LGT Group, the private banking and asset management group owned by the Princely House of Liechtenstein. Founded in 2019 as a spin-out from LGT's direct private equity activities, Lightrock deploys growth equity tickets of €10–50M into companies demonstrating measurable positive impact across climate, health, and financial inclusion. The firm operates from London with offices in Basel, New Delhi, São Paulo, and other cities, giving it an unusually broad emerging-market reach alongside its European portfolio. Notable portfolio companies include Bima, Karma Kitchen, and Proxona. Lightrock occupies a distinctive position in European impact investing: it combines the balance sheet credibility of a century-old royal banking group with a focused mandate, operational on-the-ground presence, and a willingness to invest in geographies and sectors that conventional growth equity skips. For Swiss and European founders building in healthcare access, climate solutions, or financial inclusion, Lightrock is one of the few growth-stage investors that evaluates impact metrics alongside financial ones.
