Louis Warner's path into venture investing started far from finance: he trained as an engineer in South Africa, served in a special forces battalion, worked as a mechanical engineer and later as an engineering lecturer, then spent years running travel-tech and media businesses before six years as COO of Founders Factory, giving him a builder's view of startups rather than a purely financial one. At G-Force, he invests in climate companies based on themes rather than regions, looks for founders who combine hardware and software, treats early revenue as proof a business works, backs companies with money, hands-on help, and grant support, and stays close to company building through board seats and advisory roles alongside his investing.
