TIREFLY Raises Seed Funding to Scale AI-Certified Used Tire Platform Nationwide

TIREFLY, a South Korean mobility and recommerce startup operating an AI-powered certified used tire distribution and mobile installation platform, has secured seed investment from CNTTech Fund No. 22.

The company runs two core services: Re:tire, which uses AI precision scanning technology to analyze used tire conditions and standardize grading and pricing, and TireFly, a nationwide mobile installation and maintenance service. The used tire market in South Korea sees annual replacement demand of approximately two million units, yet the lack of standardized distribution channels has long created quality distrust and transaction inefficiencies for both consumers and businesses.

TIREFLY’s proprietary AI scanning system operates at 19-micrometer precision, enabling data-driven condition analysis and automated grading and pricing. The platform integrates a nationwide mobile installation network with logistics infrastructure to deliver an end-to-end service from distribution through to installation. The company has validated its business model through B2B partnerships with major clients including Lotte Rent-a-Car, SK Rent-a-Car, K Car, Coupang, and Kumho Tire, reaching cumulative revenue of approximately $745,000 (KRW 1.13 billion) within 18 months of founding.

Looking ahead, TIREFLY plans to build out its SBOT (Sensor Board On Tire) platform to manage tire lifecycle data as part of a SaaS business expansion, with longer-term ambitions to enter overseas markets and move into end-of-life tire recycling.

“With this investment, we plan to expand our used tire inventory and logistics infrastructure while advancing our AI-based inspection and automation systems,” CEO Taehwan Kim said. “We aim to build a trustworthy certified used tire market and set the standard for the domestic used tire industry.”
