Dioseve is developing ReproNest (development code DIOS-101), a co-culture IVM product that uses ovarian support cell-like cells differentiated from iPS cells to support maturation of immature oocytes. The co-culture approach cultivates patient-derived oocytes together with support cells in the same system and is not intended as a cell therapy for administration into the body. Non-clinical studies reported by the company have shown potential benefits in supporting oocyte maturation compared with conventional IVM culture conditions. The company's technological strength is its proprietary differentiation induction technology, which it says enables efficient induction of oocytes and ovarian somatic cells from iPS cells and production of ovarian support cell-like cells. Dioseve sees applications in fertility preservation (including oocyte freezing), treatment of patients at high risk of OHSS, and rapid fertility preservation before cancer treatment. The recent funding will support validation, manufacturing and quality control setup, reproducibility assessment, regulatory compliance work, and business development to advance ReproNest toward practical application.

CULTA applies a proprietary, non-GMO, AI-powered breeding process that shortens new variety development from the traditional ten years to roughly two, enabling rapid creation of climate-resilient fruit crops. To date the company has produced four strawberry varieties, including its flagship “SAKURA DROPS,” which delivers about 30% higher yield, roughly 40% higher sugar content, and maintains quality for more than ten days even when harvested fully ripe. CULTA contracts growers, buys their entire output, and manages sales and marketing itself, giving it end-to-end control of supply and brand. Production is already scaling in Japan and Malaysia, with berries sold in Singapore, Malaysia, Hong Kong, and Thailand, and over 100 Japanese farms cultivating the varieties. The firm plans to greatly expand Southeast Asian production, enter Australia, and begin sales in Japan while pushing variety registration overseas. Future R&D targets include additional strawberry lines suited to large farms in Australia, North America, and Europe, as well as new grape and apple varieties and eventual work on coffee and banana. Including the current round, CULTA has raised roughly ¥1 billion (~US$7 million) in total funding.

Sotas is a company that has recently centered its efforts on applying artificial intelligence, positioning itself to make a significant impact within the chemical sector. Management reports that the business has grown 2,800 % since its previous funding round and is currently expanding at more than 15 % month-over-month. The team emphasises that, despite rapid traction, they still regard their mission as unfinished and intend to become a major player in the chemical industry over the next two years. To support this ambition, Sotas is actively hiring and will host recruitment events in partnership with its new lead investor. The company’s strong growth has been credited to the “dedicated execution” of its members, and leadership is committed to “shifting gears” for the next phase of expansion. No specific revenue or user figures were disclosed, but the exceptional percentage growth highlights accelerating commercial momentum.

REVORN integrates odor sensing, AI formulation and diffusion hardware to digitize smell so it can be recorded, transmitted and replayed like other media. Its platform combines the Obre sensor (detects airborne odor molecules), the Hearom diffuser and fragrances (blends multiple aroma materials in space) and the iinioi® cloud (stores detection data and generates fragrance recipes via machine learning). In 2024 the company’s proprietary sensory-evaluation AI received patent recognition and its efficacy has been validated in multiple use cases. CEO Hiroaki Matsuoka founded the company while at Nagasaki University after noting disaster-response robots lacked a "nose." With fresh capital the team plans to build higher-precision, portable sensors and automatic fragrance reproduction devices and to broaden adoption across food & beverage, cosmetics, healthcare, automotive and general-purpose applications. To date the firm has raised ¥1.35 billion in total funding.
