Allganize lists on Tokyo Growth Market at 1,260 yen offering price

Allganize Holdings listed on the Tokyo Stock Exchange Growth Market on November 4, 2026, with an offering price of 1,260 yen per share. The stock opened at 1,351 yen, 7.2% above the offering price, and closed the session at 1,250 yen.

Global Brain, an investor in the generative AI company, published an article on its web magazine on November 5 describing Allganize's IPO preparation and the background to its investment, according to platum.kr.

A Global Brain director in charge of IPO support said the hardest part of the listing was organising the tax and legal structure spanning the US, Korea and Japan. The company restructured in 2021 so that its Japanese entity became the parent of the US entity, a corporate inversion.

According to the same director, Allganize had 240 corporate customers as of the end of June 2026, and revenue for the fiscal year ended September 2025 nearly doubled year on year, with net income returning to profit. The group has fewer than 100 employees across Japan, Korea and the US.

An eight-year relationship

Global Brain's connection to the founder dates back to 2013, when its CEO heard the Allganize CEO's elevator pitch at an event in Seoul. The firm invested in 5Rocks, an earlier startup founded by the same CEO, through the KDDI Open Innovation Fund in August 2013; 5Rocks was acquired by US company Tapjoy in 2014. Allganize was founded in the US in 2017 and received seed investment from Global Brain through KDDI Open Innovation Fund 2 that year, before opening a Japanese entity in 2019 and launching the Alli LLM App Market in September 2023.
