Liesl Eisenbeiss, a fourth-generation member of the German Holsten brewing dynasty, is experimenting with systems investing through The Good Investors (TGI), a European network of four wealthy families. TGI invested $1.25mn in Koko Networks, a bioethanol stove business in Kenya that by 2023 had reached over 1 million households. The venture aimed to reduce indoor air pollution and deforestation.
Eisenbeiss’s risk-taking marked a shift from traditional wealth management. By 2026, Koko Networks collapsed, and TGI lost its entire investment—a painful lesson in systems investing. Despite the failure, Eisenbeiss remains committed to using her inheritance meaningfully, navigating the complex legacy of her family’s wealth and her own journey into impact investing.
