The firm’s leadership includes Luis Daniel Arbulu, ex-Google Investment Lead and former partner at Salkantay Ventures, who serves as Managing Director, while Lería Luksic participates on the advisory committee. The firm’s name, "Sunna," inspired by the Germanic personification of the sun, reflects its vision of illuminating new paths in sustainable growth globally. Since inception, Sunna has evolved to emphasize industrial decarbonization and hardtech innovation, expanding its portfolio with companies like Gravis Robotics, Terrablaster, and Magnefy that focus on industrial automation, agricultural nutrient management, and grid infrastructure monitoring[1][4].
