Second Syndrome announced on the 20th that its self-storage brand Mini Storage DaLock has been ranked first in the lifestyle services self-storage category at the '2026 Korea Consumer Satisfaction Index'.

This award was co-hosted by Hankyung Business and the Korea Financial Economy Newspaper and organized by the Korea Media Marketing Group. Brands in each field are selected by synthesizing actual consumer experiences, brand satisfaction, and evaluations by a panel of professional judges.

DaLock won first place in the category for the first time in 2017 and has won for 10 consecutive years up to this year. The company explained that DaLock is the only brand in the self-storage field to be selected as number one for 10 consecutive years.

Self-storage is a service that allows renting a separate storage space near a residence or business for a necessary period. DaLock provides services for various urban storage demands, from individuals' seasonal items and moving luggage to e-commerce sellers' inventory.

Launched in 2016, DaLock has been expanding its branches to major regions nationwide, including the metropolitan area. As of August 2026, it operates 250 branches nationwide, with a total exclusive area of about 12,000 pyeong and approximately 20,000 storage units.

The cumulative number of members was tallied at 120,000. Second Syndrome believes that securing repetitive demand from users, with existing customers returning to use the service at a rate of 92%, also influenced this evaluation.

DaLock operates based on an unmanned and non-face-to-face usage environment, allowing customers to choose their storage space and usage period. It has expanded its target users not only to individual customers lacking residential space but also to small business owners in need of logistics space.

In the second half of this year, an artificial intelligence-based 'digital inventory' feature will be introduced. When a customer takes a photo of the stored items, the AI recognizes the items, categorizes them by type, and organizes them into a list.

Once this feature is applied, customers can check their stored items via mobile or other devices without having to visit the storage facility. It is expected to improve convenience for individuals storing multiple items for a long period or e-commerce sellers managing product inventory.

With the introduction of digital inventory, Second Syndrome will expand services that connect self-storage spaces with stored item data. The company plans to expand its existing warehouse rental-oriented business into the AI-based space and inventory management sector.

Hong Woo-tae, CEO of Second Syndrome, said, "For the past 10 years, we have focused on creating facilities and operating systems where customers can store their items with peace of mind. Based on accumulated operation data and technology, we will advance our services and seek business opportunities in the global market."
