The vendor opportunity at Izakaya Sea-Sun
Izakaya Sea-Sun is a full-service restaurant concept headquartered in California. For software vendors, the immediate addressable market is defined by a single franchised unit, as disclosed in the 2026 FDD. The number of company-owned locations was not disclosed. This micro-system presents a highly contained sales opportunity, where landing the one franchisee or the franchisor itself would represent 100% market penetration. The royalty rate is set at 3.0%, and the initial franchise term runs for 5 years. No average unit volume (AUV) was reported in the available data.
Who controls software purchasing
Technology purchasing decisions appear to rest with the corporate entity. The 2026 FDD lists three officers: Seungmin Jung (CEO), Namhun Kim (CFO), and Jungsu Na (Secretary). In a system of this size, the CEO and CFO are the most probable contacts for a software pitch, as there is no dedicated CIO or VP of Technology on file. Vendors should prepare to engage directly with financial and operational leadership at the HQ level, as no multi-unit operators were mapped in our corpus.
Mandated and current tech stack
The 2026 FDD does not capture any mandated or recommended technology systems. This means there is no franchisor-imposed POS, inventory management, or scheduling platform that a vendor must displace or integrate with. For a sales prospector, this is a blank-slate environment. The absence of a tech mandate suggests the single franchisee may have autonomy over their operational stack, or that the franchisor has not yet standardized technology as the system is in its earliest stages.
Procurement, renewals, and timing
Procurement signals from Item 8 of the FDD were not captured, leaving the designated-supplier versus open-market question unanswered. The renewal conditions, however, are clearly defined in Item 17. The franchisor may extend or grant a new agreement if the franchisee is in substantial compliance. The franchisee must serve notice of intent to renew not less than 12 months nor more than 18 months before the initial 5-year term expires. This renewal trigger is the most concrete timing signal for a vendor: the franchisee may be required to remodel the restaurant at their own expense and sign the then-current agreement, which could contain materially different terms. A remodel and contract refresh represent a natural inflection point for evaluating new software.
How to read the Izakaya Sea-Sun FDD
The Franchise Disclosure Document is the foundational research asset for any vendor building a target account list. The embedded viewer below contains the full 2026 filing. When reviewing it, focus on Item 11 for any franchisor obligations regarding technology, Item 8 for procurement restrictions, and Item 17 for contract lifecycle events. Because this is a single-unit system with no parent company on file, the document will be concise, but every clause matters when your total addressable market is one location.
