SoftBank Group's Vision Fund will lead a ¥13.7 billion ($101 million) Series D fundraising into Japanese startup LegalForce, in the world’s biggest tech investor’s fourth outlay in its home country.

LegalForce, which uses AI to screen contracts for loopholes and potential legal risks, said other participants in the round include new investors Sequoia Capital China and Goldman Sachs Group, as well as existing backers Mitsubishi UFJ Capital and Mizuho Capital.

The fundraising lifts the total amount raised to ¥17.9 billion, the company said in a release on Thursday. The startup has 2,000 clients, including Japanese companies Nomura Holdings and All Nippon Airways.

LegalForce said it will use the funds on research and development and on expanding its sales team to win new customers.

SoftBank’s investment in LegalForce is far smaller than the billions the Vision Fund wielded in its heyday, representing founder Masayoshi Son’s new cautious approach.

The company logged a record ¥1.7 trillion loss in the year ended in March as a global downturn in tech shares deflated its big bets on companies such as Chinese ride-hailing company Didi Global Inc. and South Korean e-commerce leader Coupang.

Son had previously said Japanese startups grew too slowly for the Vision Fund, as most catered only to the domestic market. But it has since shifted strategy to invest smaller sums and expanded its team at home.

Thursday’s investment follows SoftBank’s bets in AI Medical Service, a Tokyo startup specializing in endoscopy; Aculys Pharma, which has rights to develop a treatment for narcolepsy and sleep apnea in Europe; and Soda, which operates an online marketplace for sneakers.
