About Jinghan Hao
Brett Martin simultaneously runs Charge Ventures as Co-Founder/Managing Partner while building Kumospace as President/Co-Founder, giving him a current operator's perspective on remote work and AI as he deploys capital at pre-seed and seed stages. He uses a "Spreadsheet for life" system he started in his early twenties to map long-term goals and intentionally chooses roles and projects that move multiple objectives forward at once, creating a portfolio of careers as VC, founder, and Columbia Business School professor that reinforce each other.
