United backs Rice Capital Fund II, LP for YC startups

Rice Capital is built around the network Taro Fukuyama developed at Y Combinator, where he was the first Japanese founder to graduate and later sold his US startup Fond. That background is the fund's stated edge: early access to promising YC-selected companies. United says it has already seen the value of that access through its investment in the first Rice Capital fund, citing Fukuyama's track record, the growth of portfolio companies, and the information he provides from a viewpoint versed in both the US and Japanese markets.

United's own investing centers on Japanese seed- to early-stage startups, with AI-driven transformation of existing value, operations and industry structures as one focus area. The new commitment therefore serves two purposes at once. It is a financial bet on US AI market growth, and it is a way to collect examples, business models and investment trends from abroad that United can apply when selecting Japanese candidates. United also expects introductions from Rice Capital to widen its US deal flow.

The fund's stated plan is to deploy the capital it raised into YC-selected US startups and promising Japanese startups. United describes all of its investing as self-funded, which it says allows flexible and quick decisions — a detail that matters for how fast it can act on opportunities surfaced through the fund.
