Maritime Fusion

Maritime Fusion is building fusion reactors for ships and off grid energy markets. En route on this endeavor we’re commercializing High Temperature Superconducting (HTS) cable technology for power distribution while advancing the physics basis of our HTS tokamak to decarbonize global shipping. Breakeven fusion is coming soon, but the first-of-a-kind (FOAK) reactors will be costly, high maintenance, and have low capacity factors, leading to 5–10x higher electricity cost on the grid.

YourChoice Therapeutics

match 61

YourChoice Therapeutics is revolutionizing the global contraceptive market. Our vision is to develop non-hormonal contraceptives to provide both women and men with birth control options that lack the associated risks of hormone-based options but are equally effective. Traditionally, it has been the women’s financial and health burden to have a contraceptive in place. Our first goal is therefore to bring a novel non-hormonal, on-demand and low cost female contraceptive to the market that will sub
