Investor Profile: Atinum Investment — Thesis, Cheque Size & How to Apply

If you are raising capital and researching how to get funding from Atinum Investment, this profile is your starting point. Atinum Investment is a Series A, growth stage, pre-IPO investor focused on AI, semiconductors, deep tech, bio and healthcare, IT services, games and content, with AUM 1.86 trillion won (cumulative AUM 2.4856 trillion won); Atinum Growth Investment Fund 2023: 860 billion won; National Growth Fund large-scale category: 500 billion won fund to be formed. Below: its thesis in its own terms, what it looks for, the companies it has backed, and the practical route founders use to get a pitch in front of the team.

Atinum Investment funding: the investment thesis

A first-generation independent Korean venture capital firm (roots in Cheil Venture Capital, established 1988) investing in domestic and international startups with a philosophy focused on companies' intrinsic value. Its signature strategy is the 'single large fund' — concentrating hundreds of billions of won in one fund to follow portfolio companies from Series A through pre-IPO with long-term, conviction-driven follow-on investment.

Cheque size and fund firepower

Atinum Investment has publicly disclosed AUM 1.86 trillion won (cumulative AUM 2.4856 trillion won); Atinum Growth Investment Fund 2023: 860 billion won; National Growth Fund large-scale category: 500 billion won fund to be formed. That scale tells you two things: the firm can lead rounds rather than only follow, and it has the reserves to support winners in follow-ons. Founders should size their ask to the stage the firm plays at — Series A, growth stage, pre-IPO — rather than to the headline fund number.

Sectors and stages

The firm invests across AI, semiconductors, deep tech, bio and healthcare, IT services, games and content, and its sweet spot is the Series A, growth stage, pre-IPO. If your startup sits outside those sectors, this is not your investor — a focused mandate cuts both ways. If you are inside it, you are speaking to a team that sees dozens of comparable companies a year and will benchmark you against them.

How to apply for funding

Atinum Investment has no publicly documented pitch route in the sources read for this profile. The default playbook applies: a warm introduction through a portfolio founder or a co-investor beats a cold email, and the contact details on the firm's official site are the legitimate front door.
