RideFlux bets paid trucking is L4's first revenue; Korea's first AV software IPO
Ex-LG engineers' full-stack L4 software startup runs Korea's first paid autonomous freight with Hanjin, then files for KOSDAQ.
RideFlux (라이드플럭스)
What the business is
Jeju/Seoul-based autonomous-driving software company selling a full-stack Level 4 stack - perception, localization, planning, control, HD mapping and remote operation - that runs on passenger cars, buses and heavy trucks.
Starting capital：Cumulative ₩88.2B (~$64M) by August 2026 (Pulse); the December 2025 pre-IPO first close was ₩20B with Atinum Investment and Korea Development Bank each investing ₩10B (Seoul Economic Daily).
How it started
RideFlux was founded in May 2018 by CEO Park Joong-hee and CTO Yoon Ho, both former LG Electronics executives, to build full-stack Level 4 autonomous software rather than vehicles. It moved its headquarters to Jeju in April 2019 to train on coastal, mountain and bad-weather roads, won its first MOLIT operating permit in August 2019, and in May 2020 launched Korea's first real-time demand-responsive autonomous shuttle service between Jeju airport and a Socar station.
What happened
The company kept to software and phased demonstrations: autonomous buses and shuttles across Jeju, Busan, Seoul and Sejong, then urban driverless-seat testing in Seoul's Sangam district that passed 3,300 hours. In April 2026 it won Korea's first permit for paid hub-to-hub autonomous trucking covering highway plus urban sections, and on July 1, 2026 launched the country's first paid autonomous freight service with Hanjin on a 116-km Gunsan-Jeonju-Daejeon route. It raised a ₩20B pre-IPO first close in December 2025 (Atinum and Korea Development Bank each investing ₩10B) and passed KRX technology evaluation with A ratings from both designated agencies in May 2026.
How it ended up
On course for Korea's first L4 autonomous-driving IPO: RideFlux filed its preliminary KOSDAQ listing application on August 14, 2026 (announced August 18), targeting a second-half listing with Korea Investment & Securities and Woori Investment & Securities as underwriters.
Background
RideFlux is a South Korean autonomous-driving software company founded in May 2018 by Park Joong-hee and Yoon Ho, both former LG Electronics executives. Instead of building vehicles, it develops the full Level 4 stack - perception, localization, prediction, planning, control, HD mapping and remote operation - as a software platform called RideFlux Driver that runs on passenger cars, buses and 25-ton trucks.
Its founding bet was that commercialization depends on choosing the right testbed and revenue path. The company moved its headquarters to Jeju in April 2019 to train on coastal, mountain, highway and severe-weather roads, and in May 2020 began Korea's first real-time demand-responsive autonomous shuttle service between Jeju airport and a Socar station, later adding autonomous buses and shuttles in Jeju and Busan. Those public runs produced the data, permits and safety record that later unlocked paid commercial routes.
The strategic turn came in 2026: rather than waiting for robotaxis to pay, RideFlux went after middle-mile freight. In April 2026 it became the first Korean company licensed for paid hub-to-hub autonomous trucking covering highways and urban sections; on July 1, 2026 it began Korea's first paid autonomous freight service with Hanjin, running a 25-ton truck three times a week on a 116-km Gunsan-Jeonju-Daejeon route. CEO Park Joong-hee framed the launch as proof that its AI had settled on a revenue-generating trajectory in a real logistics operation.
Capital followed the milestones: cumulative funding reached ₩88.2B (~$64M), including a ₩20B pre-IPO first close in December 2025 with Atinum Investment and Korea Development Bank each putting in ₩10B, and in May 2026 both KRX-designated agencies gave RideFlux A ratings. On August 14, 2026 it filed its preliminary KOSDAQ listing application, aiming to become the first Level 4 autonomous-driving software company listed in Korea in the second half of 2026.
What has to be true
- Software-only positioning lets one stack serve cars, buses and trucks instead of betting on a single vehicle program.
- Jeju's varied roads and weather gave the founders a defensible data and testing story before competitors consolidated in Seoul.
- Paid hub-to-hub trucking monetizes existing permits and infrastructure, while robotaxi rules and revenue remain unsettled.
- The Hanjin contract converts B2G demonstration history into B2B revenue, which is what a KOSDAQ listing review demands.
- IPO timing lets RideFlux raise expansion capital while it still holds first-mover claims in Korean L4 commercialization.
What can be applied
In a capital-heavy category, sequence revenue before hype: prove software on subsidized public routes, then convert that permit stack into paid B2B freight, then raise public money.
Aftermath
As of early September 2026 RideFlux is Korea's first L4 autonomous-driving startup in the KOSDAQ pipeline: its preliminary review application was filed August 14, 2026 and announced August 18, with a listing targeted for the second half of the year. The Hanjin paid freight service continues on the 116-km middle-mile route, and the company says it is in talks with more than 10 logistics and manufacturing firms to expand to Chungcheong, Gangneung and Jeju. It also plans a public robotaxi service in Seoul's Sangam district this year, and is part of a Hyundai-led demonstration project in Gwangju.
