Overview Energy is a startup working to harvest sunlight in space and transmit it to Earth, enabling solar farms to deliver power both day and night. The company plans to deploy large solar arrays in geosynchronous orbit (~22,000 miles up) that convert sunlight into infrared laser beams aimed at ground-based receivers co-located with existing solar facilities. A recent airborne test saw the system successfully send power across 5 km from a light aircraft to a ground receiver, demonstrating proof of concept. Future milestones include launching a demonstration satellite to low Earth orbit in 2028 and beginning megawatt-scale power delivery from geosynchronous orbit by 2030. By re-using existing solar farms, Overview hopes to sidestep the need for bespoke ground stations and reduce public-safety concerns associated with high-power beams. The company faces competition from firms pursuing microwave-based wireless power as well as falling grid-scale battery costs. Overview has raised $20 million so far to fund technology development, backed by Aurelia Institute, Earthrise Ventures, Engine Ventures, EQT Foundation, Lowercarbon Capital, and Prime Movers Lab.

Milvus Advanced is an Oxford-based deep-tech startup that designs nanoalloy materials capable of matching or exceeding the properties of platinum-group and other critical metals. Its proprietary, independently validated alloys offer superior durability and performance in electrochemical and optoelectronic systems while relying only on abundant elements. Operating on a B2B model, the company targets sectors such as clean energy, transport, chemical manufacturing and electronics, where cost, performance and sustainability intersect. By removing dependence on geopolitically fragile and expensive raw materials, Milvus aims to stabilize supply chains and lower environmental impact. Early pilots are underway with global electrolyser OEMs and chemical manufacturers, showing initial commercial traction. Armed with fresh capital, the firm intends to scale production, grow its team, enter the U.S. market for manufacturing and partnerships, and expand R&D into additional material systems. No revenue or user metrics have yet been disclosed, but management positions Milvus at the forefront of a new materials revolution that underpins the energy transition.

NitroVolt is developing a container-sized Nitrolyzer system that combines air, water, and renewable electricity in an electrocatalytic ammonia synthesis process. The company aims to decentralise ammonia production by producing green ammonia directly at farms, reducing distribution emissions and supply-chain vulnerability. Its process removes fossil fuels from production, making the ammonia 100 percent renewable, carbon-free, and competitive with current ammonia prices. With a newly secured seed round, NitroVolt plans to take its lab technology to the real world, scale the technology, and build a demonstration unit on a farm. The funding will also be used to identify and forge partnerships and suppliers to support scaling and system construction. CEO Suzanne Zamany Andersen highlights both environmental impacts through CO2 abatement and societal impacts by improving access to nitrogen fertilizer in exposed regions. NitroVolt is developing a container-sized ammonia synthesis unit aimed at giving farmers control over on-site fertilizer production using only air, water and renewable electricity. The company targets the agricultural sector with a product designed to decarbonize nitrogen-based fertilizer production and reduce logistics costs and supply-chain vulnerabilities. NitroVolt says the system will make farm-level production more resilient to external factors and political issues. Led by CEO Suzanne Zamany Andersen and CTO Mattia Saccoccio, the team is positioning the product as a locally produced alternative to centralized fertilizer supply. The company raised €750K in pre-seed funding to scale production and expand its business reach. NitroVolt is based in Copenhagen, Denmark.

QarboTech develops QarboGrow, a liquid biostimulant concentrate that uses carbon quantum dots to penetrate leaves, optimize photon absorption and electron transfer in chloroplasts, and improve plant health and yield. The company supplies QarboGrow as a concentrate farmers mix with water and spray onto foliage; it can be integrated into existing spray regimens and mixed with other crop inputs. QarboTech sources carbon quantum dots from agricultural waste biochar using a patented extraction process and produces its material in liquid form to reduce nanomaterial handling hazards. The firm has scaled manufacturing from roughly 200 liters per month in a university lab to about 20,000 liters per month at a new facility in Puchong, and expects to reach 100,000 liters by March next year with expansion funded by the recent raise. Product classification and approvals: QarboGrow is classified as a biostimulant, has approvals in Malaysia, and is undergoing regulatory review in Indonesia (likely through end of 2025). Field validation includes 450 hectares of rice with reported tonnage increases of 10–50% and smaller trials (1–10 hectares) across leafy and fruiting vegetables, melon and pineapple; the company claims high ROI for farmers (e.g., $5 returned per $1 spent in rice; up to 10x on lettuces). QarboTech is extending IP protection from its extraction process to application areas and is targeting larger plantations and medium‑scale farms as it collects more trial data. Qarbotech is a Malaysia-based agritech startup. The company was reported to have raised a $700,000 seed round. The round was led by 500 Global. The article does not provide details on Qarbotech's specific product offerings or technology. No operating metrics, valuation, or use of proceeds were disclosed in the coverage. Additional investor names and the firm's future plans were not included in the report.

Fertifa offers an employer-facing platform and app that provides reproductive health and fertility benefits, including fertility preservation (egg/embryo/sperm freezing), IVF/IUI/ICSI, contraception, surrogacy, adoption, menopause, endometriosis, PCOS, fibroids, STI care and men’s sexual health. The company combines educational resources, an in-house clinical team led by medical director Dr. Gidon Lieberman, prescription writing and fulfillment, and reimbursement administration. Fertifa monetizes through a per-employee-per-month pricing model and charges a 5% fee on transaction volume with an annual minimum for reimbursement administration. The startup says it increased revenues 10x year-over-year, has saved patients more than £1.5 million via employer-funded allowances and saved employers about £250,000 in compliance by identifying ineligible claims. Fertifa works with clients including Lululemon, Meta, Bain Capital and Virgin and currently has 22 employees. The company plans to launch new services such as treatment financing, scale up enterprise sales, become the U.K. market leader within a year and the EMEA category leader by the end of 2024. Fertifa operates a next-generation digital fertility clinic and employee benefits portal that combines at-home diagnostic testing, remote video consultations, medication delivery, and employer-facing educational resources. The platform is used to deliver fertility support and benefits to HR/People teams, and the company works directly with corporate clients whose employee bases range from a few hundred to more than 10,000 each. Fertifa says it already collaborates with partners to bring its services to more than 700,000 U.K. employees.
