| General Fusion | General Fusion pursues a commercially oriented path toward fusion energy by developing a magnetized target fusion (MTF) technology. The company applies advances in plasma physics, modern electronics, materials, and compression mechanisms to generate fusion-relevant conditions. It operates a demonstration system, Lawson Machine 26 (LM26), thatinjects magnetized plasma into a liquid metal liner and compresses it using coordinated mechanical pistons to reach high temperatures and pressures. The technology serves as a practical stepping stone toward building a fusion demonstration facility and ultimately delivering fusion-derived electricity to the grid. The approach focuses on closing the gap between demonstration milestones and a deployable power-plant system. | $65M | Series E | Dec 16, 2019 |  |
| Realeyes | Realeyes is a leader in computer vision and emotion AI that empowers companies to create remarkable customer experiences that drive growth.

| OptiNose | OptiNose develops nasal drug delivery technologies and novel combination drug/device therapies. The drug delivery technologies are based upon a unique and patent-protected principal "Bi-Directional Delivery" which allows drugs to be more efficiently delivered to the nasal cavity. By applying its drug delivery technology, most of thedose is deposited beyond the nasal valve in the upper posterior two-thirds of the nasal cavity, unlike traditional devices. The OptiNose delivery devices have high dose reproducibility and avoid drug deposition to the lungs. In summary, technology fulfills the ideal requirements for nasal drug delivery. Clinical trials have shown that devices can provide a faster onset of action, greater effect with a lower dose, and reduced side effects. The company has offices in Norway and the UK. | $37M | Series D | May 09, 2017 |  |

It rapidly lowers excessive NO production in cerebral vessels and tissues, thereby preventing life-threatening increases in intracranial pressure and associated inflammatory processes following traumatic brain injury. | $21.2M | Series G | Jan 21, 2016 |  |
