INX International Ink Co.
Founded in 1992 by a South Korean industrial family, INX International Ink Co. initially operated as a manufacturer of printing inks and coatings before evolving into a dedicated single-family office investment vehicle. John Huh, a former investment banker, joined the firm to professionalize its direct investment arm, eventually becoming managing partner and relocating the primary investment office to the San Francisco Bay Area. The office deploys capital exclusively for its founding family, with no outside limited partners. The firm pursues a concentrated, stage-agnostic venture strategy, writing equity checks from Series A through pre-IPO rounds. Target sectors cluster around enterprise software, fintech, and digital health, with a geographic emphasis on Silicon Valley and South Korea. INX has historically co-invested alongside top-tier venture firms such as Sequoia Capital and Accel. Confirmed portfolio positions include Coupang, the South Korean e-commerce giant that went public on the NYSE in 2021, and Uber Technologies, held prior to its 2019 IPO (per Bloomberg, 2019). The office also evaluates industrial-tech and cybersecurity opportunities that bridge its legacy manufacturing expertise with modern venture. The investment team operates from offices in San Francisco, New York, and Schaumburg, Illinois, maintaining a lean, partnership-driven structure. Jake Park, based in New York, leads deal origination and due diligence alongside Huh. The family's original ink-manufacturing business, which still operates under the INX International Ink Co. name, provides a stable operating-company backbone that insulates the venture portfolio from redemption pressure. In April 2024, INX participated in a $200 million Series C round for a South Korean AI-chip startup, signaling continued appetite for deep-tech bets tied to the family's home market (per The Korea Economic Daily, April 2024). INX operates with an under-the-radar posture uncommon among Asian family offices its size, avoiding PR and maintaining no dedicated investor-relations function. Its hybrid structure — a cash-flowing industrial business funding a pure-play venture portfolio — allows multi-decade holding periods without the exit-timing constraints of a traditional fund vehicle. This places it in a small cohort of family offices that use an operating company as a permanent capital base rather than merely a legacy asset to be managed.

Frequently asked questions
Who runs investment decisions at INX International Ink Co.?
Managing Partner John Huh leads the investment team from San Francisco, with Partner Jake Park handling origination and due diligence from New York. The two make decisions jointly on behalf of the founding family, with no external investment committee involved.
How does INX source proprietary deal flow?
INX sources primarily through long-standing relationships with top-tier venture firms, including Sequoia Capital and Accel. Its dual presence in Silicon Valley and South Korea provides access to cross-border opportunities that generalist US funds often miss.
Is INX structured as a single family office or does it operate more like a venture firm?
INX is a single-family office managing capital exclusively for one South Korean family. It does not raise outside funds or charge management fees, though its direct venture investing approach resembles that of a lean venture capital partnership.
Does INX participate in fund commitments or only direct deals?
INX is known primarily for direct equity investments rather than fund-of-fund commitments. The firm writes direct checks into venture rounds, commonly co-investing alongside established VC firms rather than through blind-pool fund vehicles.
How is INX related to the ink manufacturing business of the same name?
The ink manufacturing company is the original family business and continues to operate. It serves as a permanent-capital base that funds the venture portfolio, giving the office indefinite holding periods without external LP redemption pressure.
