Investment thesis

Kero Development Partners invests in innovative engineering technologies that solve real-world problems and have positive impacts on society or the environment. Founded in 2017 by engineers Roger Doo and Keith Jones following their exit from Henrob, Kero seeks opportunities based on promising, patented or patentable ideas backed by a committed core team. The firm takes an active, hands-on, value-enhancing approach — providing capital, operational support, IP strategy, company secretarial services, and mentorship — allowing it to invest where more traditional investors do not. Kero is led by engineers and entrepreneurs who understand the challenge of developing new technology and are committed to investing ethically in solutions that benefit society and the environment.
