During the South Summit, Sergio Furio, founder of Creditas, and Maex Ament, General Partner at Earth Fund, met at the main stage to discuss how technology-driven financial models can unlock capital for climate action. Set against the backdrop of a global push for decarbonization, the conversation highlighted how fintech innovation can simultaneously drive profitability and environmental responsibility.
Furio shared how he tried to pioneered ESG investments in Latin America, funding companies as Voltz, an electric motorcycles manufacturer, and Lemon Energy, that builds solar panel platforms and distributes green energy. For him, the climate-finance intersection isn’t a side project: it’s almost a second career. “It’s not just about sustainability for the planet,” he said, “but also the sustainability of business models.”
Ament, co-founder of Taulia and now a full-time climate investor, reinforced that, indeed climate is not a sector, but an horizontal issue that touches everything. At Earth Fund, his approach is clear: back early-stage companies with profit-driven models that happen to be green. He coined the term “climate dynamism” to describe this dual focus: investments that are “better, cheaper, faster, safer,” and environmentally beneficial. Ament distanced himself from traditional “impact investing,” emphasizing that Earth is built for returns first, and change second, not the other way around.
Nuclear Energy
The panel also tackled the rekindled debate over nuclear energy, with Ament delivering a stark verdict: “Turning off the reactors was the stupidest idea ever. Nuclear is clean. Nuclear is safe, and I certainly hope we get it back”, he claimed. “Otherwise we lose against China”, stated, mentioning the agressive growth of the Asian giant on the sustainable energy sector.
In his point of view, nuclear energy must be part of the European mix of production, but not necessarily the primary source. The speaker admitted the challenges regarding the public opinion on the topic, but remain favorable to the implementation of such technology in Spain and Germany, as it used to be.
Crypto and blockchain
Stablecoins also took the stage, as Ament reflected on his early days building crypto infrastructure. Unlike the speculative mania of recent years, he underscored the true promise of blockchain: financial access. Implemented during the past decade, stablecoins were not took seriously back in the early days of crypto investment, Ament claimed. Stablecoins allow people in countries challenged by inflation to hold US dollars (or euros) on a phone, and, because of that, are a powerful democratization tool that mirrors the inclusive potential of impact fintech, he argued.
The conversation turned philosophical as they discussed how venture capital must evolve. Earth’s two investment buckets are “upgrading Earth” through cleaner industries and “resilience and adaptation,” preparing for climate fallout. Ament even ventured into geoengineering: “It sounds like sci-fi, but we’re going to need it. We’re out of time,” he warned. He stressed that cooling the planet might eventually require active atmospheric intervention.
In closing, both Furio and Ament agreed that the next decade will require hybrid minds—entrepreneurs and investors who think in systems, not silos. Climate isn’t just a calling, in their opinion, but instead it’s becoming a core economic opportunity.
