| Quercus aims to create effective, environmentally friendly alternatives to chemical pesticides by designing proteins from scratch, which can be regulated as biopesticides. This approach promises faster development and deployment compared to traditional methods, with potential for significant advancements in crop protection over the next few years. | $5M / Seed / Jul 29, 2026 | ||
| Hephae Energy Technology is an energy company that offers integrated drilling system to enable the generation of geothermal energy. | $17.8M / Series A / Jul 09, 2026 | ||
| Via Separations is enabling industrial decarbonization with its novel chemistries that allow manufacturing facilities to slash their energy consumption while making more product. Targeting the 12% of US energy consumption that is wasted each year separating chemicals, Via reduces the load of the process by 90%, electrifies the mostenergy-intensive step in chemical production, and generates additional revenue for the customer. Today, Via is deploying its technology in pilot trials at pulp & paper facilities to eliminate 100 million metric tons of CO2 by 2050. Via’s innovation is a highly selective and robust membrane filter that replaces the energy-inefficient heat-based separations in industrial processes. Spun out of MIT’s Department of Material Science & Engineering, Via has scaled up the technology by more than 10 million times and demonstrated working prototypes at a commercial scale. | $36M / Venture - Series Unknown / Apr 01, 2026 | ||
| V-Glass has developed next generation platform technologies that enable the low-cost production of vacuum insulated glass (“VIG”) for high efficiency windows having 3x the thermal performance of conventional dual pane windows, 2x longer life, and costing no more to manufacture. By solving the weak link in building envelopes, reducing GHGemissions, and preserving resources through avoided energy use, V-Glass technology will meaningfully impact the sustainability of our planet and wellbeing of its people. Broad patents filed in the US and abroad provide a defensible moat through 2041. At V-Glass, we know that avoided energy use is the greenest energy available. Since mid-2022, we have been consistently producing high efficiency V-Glass panels in our lab that has passed rigorous testing internally and by 3rd parties. With this, we recently shipped V-Glass panels to three potential strategic partners for their evaluation and testing, with more in the queue. We will soon migrate out of the lab and into a pilot plant where automation and robotic technology will be developed to industrialize V-Glass production for the delivery of commercial quality units at targeted price efficiency. | $3M / Seed / Mar 17, 2026 | ||
| We are a biotech company re-shaping the future of insect control with a unique technology platform that combines environmental sustainability and unprecedented effectiveness.As a spin-out from Imperial College London, a global leader in genetic pest control, we build upon over 20 years of research by our scientific founders, whose pioneering workin genetic control technologies has garnered global recognition.With a presence in the UK and Italy, we leverage the experience of a diverse and accomplished team from 7 countries with unparalleled experience in the scientific and technological fields and an outstanding track record in company building and management. | $12.7M / Seed / Nov 18, 2025 | ||
