JB Investment Triples Assets to 664.9 Billion Won on Robot and K-Pop Bets

JB Investment's operating assets have grown 3.3 times in under three years, from roughly 200 billion won when CEO Lee Gu-wook took office in December 2022 to 664.9 billion won at the end of September this year. The Seoul-based firm, once concentrated on early-stage ventures, now invests across AI, robotics, biotech and entertainment regardless of a company's growth stage.

At his office in Gangnam-gu, Seoul, Lee laid out his method: "The most important thing in investment is to find good companies half a step ahead of others."

"If you invest too early, it takes a long time to achieve results, and if it's too late, it's hard to expect high returns," he said. "The key to venture investment is to judge the company's growth potential and the right timing."

The caveat is obvious: timing claims are easy to make in hindsight. JB Investment's recent record, however, supplies the numbers to back them.

Where did the half-step timing pay off?

The clearest case is The Muse Entertainment, the agency behind girl group Lysenne. JB Investment put 2 billion won into the company in March this year at an enterprise value of 28 billion won. By October, after Lysenne's music climbed back up the charts and made headlines, the agency's corporate value had risen to 46.8 billion won — a 67 percent gain in about seven months.

Robotics produced the bigger multiple. JB Investment invested about 2.5 billion won in Welo Botics in March 2024, when the wearable-robot maker was valued at 49.5 billion won. The company expanded into humanoids, and its corporate value reached 421.4 billion won this May — roughly 8.5 times the entry valuation. JB Investment then added about 28 billion won more this year. The per-share valuation of the original stake has risen 6.5 times, according to the firm's own account, which remains unrealized until exit.

The firm also went abroad. In January it invested about 4 billion won in SpaceX at a corporate value of 1,180 trillion won. Following the June Nasdaq listing, that valuation has climbed 2.2 times to 2,602 trillion won as of October.

How much capital is coming back?

Recoveries, not just paper gains, have accelerated. The cosmetics brand Dalva shows the ceiling: JB Investment put in 3.3 billion won and recovered about 60 billion won — roughly 18 times principal.

Total investment recovery rose from 41.8 billion won in 2024 to 79.2 billion won last year, nearly doubling in twelve months. This year the firm had recovered 76.8 billion won by September, already 97 percent of last year's full-year figure with a quarter still to run.

What comes next?

Lee has set a target of 800 billion won in operating assets, about 20 percent above the current level. The firm also plans to expand headcount from 23 employees to 35 — a 52 percent increase that signals the build-out is not finished.

Lee, born in 1969 and a mechanical engineering graduate of Pohang University of Science and Technology with a KAIST MBA, spent 1994 to 2006 at Samsung SDS, led the Korea Advanced Institute of Industrial Technology, and ran POSCO's technology investment group from 2008 to 2022 before joining JB Investment.

The open question is durability. Chart comebacks and humanoid hype move valuations quickly in both directions, and several of the headline gains — Welo Botics, SpaceX — remain on paper. Until the recovery pipeline keeps pace with a balance sheet now two-thirds larger, the 800 billion won target rests on momentum holding.
