AlgaleX develops and cultivates DHA-rich microalgae using awamori lees (the leftover mash from Okinawa's distilled spirit) and sells its product under the Umamo brand. Its core technology is Touji-24, an AI-driven cultivation system that continuously grows DHA-rich algae; the cultivation technique is now patented. The company positions its product as an alternative feed input for aquaculture amid declining wild fish catches in Japan. Following the Series A raise of about $2 million, AlgaleX plans to scale Touji-24, expand bespoke cultivation partnerships with corporate clients, and increase hiring to support growth.

Founded in 2016, Tokyo-based Monogusa develops and operates Monoxer, a memory-optimization platform that personalizes drills and repetition to improve long-term recall. The software was first adopted by cram schools and private institutions and is now expanding into public education systems, municipalities, and enterprise upskilling programs. Corporations use Monoxer to raise qualification-exam pass rates, onboard sales staff, and capture tacit knowledge in manufacturing, retail, leasing, and other operational settings. New features in development include automatic generation of learning content from internal manuals and data, as well as sector-specific enablement tools for skills transfer in construction and manufacturing. The company recently introduced "Monoxer Junior" for early childhood learning and plans a university student service that links study with career development, plus lifelong learning offerings for professionals. Capital from the Series C round will fund product development, marketing, hiring, and new business lines. Although no revenue or user figures were disclosed, management highlighted rapid adoption across both education and enterprise markets.

Terraton’s core product is a repeatable biochar project-development system intended to let local partners build and operate biochar facilities using a franchised model. The company combines on-the-ground project development with a SaaS component to run plants, measure and verify carbon credits, and sell those credits to large buyers. Terraton argues that most biochar facilities have only been built once, and its approach is to learn from initial projects and clone the operations for new partners. The company has developed two facilities in Africa (Ghana and Kenya), both owned by local businesses that source agricultural waste from nearby producers. Together those two facilities are expected to remove about 20,000 metric tons of CO2 annually, and Terraton estimates a single facility can capture roughly 10,000 metric tons per year. The team is targeting the supply-constrained biochar market and aims to scale by enabling partners to replicate proven facilities and tap large corporate buyers seeking credits.

RLWRLD is a physical AI company building robotics intelligence that collects and learns from on-site industrial data, enabling robots to understand their environments and make autonomous decisions. After completing initial technology verification, the firm is now running joint proof-of-concept (PoC) and RX (robotic transformation) projects with major Korean companies such as CJ Logistics and Lotte, and is expanding trials in Japan through partner Z Venture. Management states that real-world validation is critical and plans to officially release a robotics foundation model in the first half of 2026. Demand for its technology is rising amid East Asia’s labor shortages, driving interest from strategic partners that control large industrial sites. Financially, RLWRLD secured about US$15 million in a Seed 1 round and has now added roughly US$26 million in Seed 2 financing, bringing cumulative seed funding to approximately US$41 million. The fresh capital supports continued product development and broader global collaborations. Key backers include Headline Asia, CJ Logistics Corporation, Kakao Investment, LOTTE Ventures, Hanwha Asset Management, Mirae Asset·emart and Z Venture.

LanzaJet develops and licenses patented ethanol-based alcohol-to-jet (ATJ) technology to create sustainable aviation fuel and renewable diesel. Its flagship Freedom Pines Fuels plant in Soperton, Georgia is the world’s first fully integrated, commercial-scale ethanol-to-fuels facility and, in late 2025, produced ASTM on-spec jet fuel, marking the first commercial-scale SAF made from ethanol. The company’s technology offers a non-oil-based, scalable solution compatible with today’s aircraft, positioning it to accelerate decarbonization in aviation. LanzaJet is also advancing Project Speedbird, a major SAF biorefinery planned for Teesside in the United Kingdom, aided by a grant from the UK Department for Transport’s Advanced Fuels Fund. An innovative multi-year tolling structure at Freedom Pines secures waste-based ethanol feedstock and guarantees offtake for all production. Financially, the firm has attracted backing from strategic investors such as Airbus, All Nippon Airways, Breakthrough Energy, IAG, Shell, and Microsoft’s Climate Innovation Fund. The latest capital raise values the company at $650 million pre-money and supports further commercial deployments of its ATJ technology.
