Sejinsa raises seed round led by Seoul Techno Holdings for on-demand car care

Sejinsa Closes Seed Round

Sejinsa (세진사), a South Korean vehicle-management platform, has raised a seed round led by Seoul Techno Holdings. The funding amount was not disclosed in the transaction details; the round is denominated in KRW.

What Sejinsa Does

Sejinsa offers on-demand car washing and maintenance through its mobile app. Customers leave their car parked where it is, and a trained crew arrives to wash it on site. The model removes the need for customers to drive to a wash location.

A core differentiator is data capture. Each service visit collects vehicle condition data that the company's AI uses to identify issues such as:

• Exterior damage
• Engine oil condition
• Battery wear
• Tire wear

The platform then recommends personalized care timing based on that data — positioning Sejinsa as a vehicle-maintenance intelligence layer as much as a car-wash service.

Growth Since Launch

Launched in 2023, Sejinsa began with night-time apartment washes and has since expanded into:

• Daytime service
• Office-building service
• Engine-oil replacement
• Tire replacement

By late 2026, the company reported surpassing 60,000 washes with more than 4,000 registered crews.

Acquisition Perspective

Sejinsa combines a mobile-first service marketplace with an AI-driven vehicle condition dataset. The on-site model — crew dispatched to a parked car — lowers friction for customers and creates recurring touchpoints for maintenance upsells such as oil and tire replacement.

The company's scale metrics are meaningful for a young platform: more than 60,000 washes and over 4,000 registered crews by late 2026 indicate an operating supply network rather than a pilot-stage concept. The expansion from night-time apartment service into daytime and office-building locations broadens the addressable customer base and service windows.

For strategic buyers in automotive services, mobility or insurtech, Sejinsa's vehicle condition data and personalized care recommendations could be relevant assets, particularly where predictive maintenance or vehicle history data carries value. The seed round led by Seoul Techno Holdings provides capital as the company continues to build out its service network and data capabilities.
