ARO InTech

What ARO InTech does

ARO InTech (주)아로정보기술) is a Seoul-based private technology company founded in 1999 that specializes in public transit data, route search, and mobility-as-a-service (MaaS) platforms in South Korea. Operating the ODsay brand — positioned as Korea's leading public transit information service — the company has spent 25+ years continuously collecting nationwide multimodal transit data covering buses, subways, trains/KTX, intercity/express buses, aviation, and maritime routes. Its core technology stack centers on a proprietary transit route search algorithm, a high-speed public transit accessibility (isochrone) service that computes a 60-minute transit radius in under 2.5 seconds, and a full-stack MaaS platform that has been validated through six rounds of demonstration testing with the Daegu Metropolitan City Smart City project under the Ministry of Land, Infrastructure and Transport.

ARO InTech distributes its data primarily through the ODsay LAB developer portal, which exposes nationwide transit APIs to a mix of self-serve developers and enterprise integrators. Major platform customers include Naver (since 2005, repeatedly selected as Co-Growth Partner), Google Maps Korea, and SK Telecom, all of which embed ODsay data into their consumer-facing transit features. Enterprise and government customers include KB Kookmin Bank and IBK Industrial Bank (large-scale workforce deployment and business trip expense automation), Samsung Bixby (voice-enabled transit accessibility), Korail (ga-G service), real estate platforms (JikBang), tourism services (Interpark Triple, Korea Tourism Organization's Visit Korea platform), and logistics providers (Acexpress). Multilingual transit services support English, Chinese, Japanese, and Vietnamese for inbound tourism.

The business model combines several revenue streams: subscription-based API/data licensing on ODsay LAB (with a freemium Basic tier and paid Standard tier), enterprise contracts for large-scale workforce deployment and business trip expense automation (10TPS+ capacity), MaaS platform licensing to government and mobility operators, GS-certified packaged software sales via the government procurement portal (조달청 벤처나라), and subsidized data sales through the Ministry of Science and ICT's Data Voucher Support Program. The company holds Inno-Biz A-grade certification, GS Grade 1 software certification, and multiple government/industry awards. It remains privately held with no disclosed funding rounds or external investors, and is led by CEO Lee Wangseok (이왕석).

Scale indicators5 records

Recent moves6 records

Expansion highlights7 records

Direct peers

• Citymapper: Urban mobility and multimodal transit routing platform offering trip planning, real-time arrivals, and MaaS integrations. Comparable to ODsay's consumer-facing map browser and developer API product.
• Moovit: Global public transit data and mobility-as-a-service platform providing APIs, SDKs, and routing to cities worldwide. Closest direct peer to ARO InTech's ODsay LAB business model, differing primarily in geographic focus (global vs. Korea).
• Transit App: Multimodal transit planning app and data platform serving North American and European cities. Comparable in its developer- and consumer-facing transit data offering to ARO InTech's ODsay platform.

Emerging players

• Optibus: AI-driven transit operations platform for scheduling, routing, and on-demand mobility. Comparable to ARO InTech's MaaS / smart-mobility platform ambitions, though focused on agency-side operations rather than passenger-facing data.
• MaaS Global (Whim): MaaS subscription service combining public transit, ride-hailing, bike-sharing, and rental cars into a single app. Comparable to ARO InTech's MaaS platform vision and Daegu-validated solution, though with a European focus.

Broad incumbents

• Cubic Transportation Systems: Large incumbent vendor of fare collection, real-time passenger information, and urban transit platforms to transit agencies globally. Comparable on the MaaS / transit IT platform dimension, with much broader scope and scale than ARO InTech.
• HERE Technologies: Global map and location data platform providing transit, routing, and MaaS APIs to enterprises worldwide. Comparable API/data platform offering at much larger scale than ARO InTech.
• TomTom: Global mapping and location technology provider with public transit routing APIs and traffic data products. Comparable in offering transit data APIs as part of a broader location-services portfolio.
• Kakao Mobility: Korea's largest mobility super-app, encompassing taxi, navigation, and MaaS services. Overlaps with ARO InTech's Korean transit routing and MaaS ambitions, but with a vastly larger consumer base and broader mobility scope.
• T Map Mobility: Korean map and mobility platform spun out of SK Telecom, integrating public transit data, taxi, and navigation. Direct competitor in Korean transit information and a partner-competitor to ARO InTech given the SK Telecom relationship.
