Universal Materials Incubator
Universal Materials Incubator, or UMI, is a Tokyo-based venture capital firm that backs materials and chemical science startups, the deep-tech founders most investors find too technical. UMI reaches water sideways, through materials: it has backed 3 water companies across 4 deals since 2015, from super-absorbent farming polymers to forever-chemical filters.

The take
Universal Materials Incubator was set up in Tokyo in 2015 to do the thing Japanese venture capital almost never does: write cheques into materials and chemistry, the slow, lab-heavy science that becomes the batteries, membranes and coatings everyone else uses a decade later. UMI runs three funds of roughly ten billion yen each, staffed by people who came out of the chemical industry rather than finance, and it likes technology that is past the science-experiment stage but still years from a factory. Water is not its headline; materials are.
Universal Materials Incubator reaches water sideways, and that angle is the whole story. Every water company UMI backs is really a materials play that happens to clean, save or recover water: EF Polymer turns orange and other fruit peels into a biodegradable super-absorbent that lets crops hold far more water per drop of irrigation; Aquafortus uses a non-thermal chemistry to pull fresh water out of brine that would otherwise be dumped; Puraffinity grows a designer adsorbent that latches onto PFAS, the forever chemicals regulators are racing to get out of drinking water. Three companies, three different materials, one water outcome each.
Universal Materials Incubator has backed 3 water companies across 4 funding rounds, mostly at Series A and Series B, the stage where a proven lab result needs real money to build its first commercial line. UMI tends to co-invest alongside deep-tech specialists such as DCVC and Burnt Island Ventures, and it brings the thing a generalist fund cannot: a building full of chemists and a rolodex of Japanese industrial partners who can actually scale a material. If your water technology is really a materials breakthrough, this is a rare door; if it is software or services, it is the wrong one.
Universal Materials Incubator is, as of early 2026, pushing well beyond Japan. UMI has signed agreements with Saudi partners NADEC and Forming Future to plant its deep-tech and localization model inside the kingdom's Vision 2030 industrial build-out, and in February 2026 it began splitting its functions into focused operating companies. For a water founder the read is simple: UMI is a patient, industrial and increasingly global home for water technology that is, underneath, a materials company.

Frequently asked
- What does Universal Materials Incubator invest in?
- Universal Materials Incubator backs materials and chemical science startups: advanced materials, coatings, batteries and the chemistry behind them, usually after the lab stage and before mass production. UMI funds water technology only where water is really a materials problem, such as super-absorbent polymers, brine recovery or removing forever chemicals from water.
- Does Universal Materials Incubator fund water technology?
- Universal Materials Incubator does fund water technology, selectively. Its three water companies, EF Polymer, Aquafortus and Puraffinity, are each a materials breakthrough first: a fruit-peel super-absorbent that saves irrigation water, a non-thermal way to recover water from brine, and an adsorbent that captures PFAS forever chemicals. A pure software-water startup sits outside its mandate.
- Who runs Universal Materials Incubator?
- Universal Materials Incubator is led by Representative Director and Managing Partner Shosuke Kiba from its Tokyo headquarters. Founded in 2015, UMI is run by partners who came out of the chemical and materials industry rather than pure finance, and it manages three investment funds of roughly ten billion yen each.
- Is Universal Materials Incubator a venture capital fund or an incubator?
- Universal Materials Incubator is a venture capital firm, not a startup accelerator, despite the word incubator in its name. UMI raises and manages investment funds that take equity in materials and chemical companies, then supports them hands-on toward commercial scale and realistic exits, rather than running a fixed-term cohort program.
- Where is Universal Materials Incubator based?
- Universal Materials Incubator is based in Tokyo, Japan, in the Tsukiji district of Chuo-ku. As of early 2026 UMI is also expanding internationally, having signed deep-tech and localization agreements with Saudi partners NADEC and Forming Future to support startups under Saudi Arabia's Vision 2030 industrial plan.
