About us
The company is the result of the strategic combination the teams of Circularis Partners (US) and Ecoa Capital (Brazil), combining complementary expertise in growth equity and scaling climate-related companies.
With over US$200 million in assets under management and more than 70 years of combined partners’ experience, Bold.t was created with a clear mission: to support companies that lead the climate transition — starting from Brazil, with a vision for global scale — with boldness and discipline.
Our name pays tribute to the German naturalist Alexander Von Humboldt, a symbol of innovation and the pioneer proponent of a systemic, interconnected view of nature. Bold also reflects our desire to lead a courageous and unique movement in the financial market aimed at catalyzing a just climate transition and protecting biodiversity
