What 세무회계 세아 does
세무회계 세아 (Seah) is a privately held tax and accounting professional services firm founded in 2009 and headquartered in Seoul's Gangnam-gu (Teheran-ro 25-gil, Seokam Building 8th floor). The firm is led by Hong Beom-jun (Representative/Tax Accountant) and Hong Yong-jun (Advisor/CPA), both formerly of Samil Accounting Corporation, one of Korea's Big 4 accounting firms; Hong Yong-jun additionally served as CFO of Fiverocks. The firm operates as a boutique practice with 11-50 employees and a single Seoul office, serving Korean domestic clients with no disclosed geographic expansion.
The firm operates four interconnected service lines: (1) Accounting & Management Support covering corporate establishment, bookkeeping, payroll, and financial statement preparation; (2) Tax Services spanning withholding, VAT, corporate tax filing, year-end settlement, restructuring tax, tax audit support, private stock valuation, and inheritance/gift tax; (3) M&A Advisory including buy-side and sell-side consulting, accounting/tax due diligence, and M&A brokerage; and (4) a specialized Startup Advisory practice covering founding, operations, fundraising, and exit/IPO stages. The core competitive positioning is institutional-grade tax and accounting expertise (Samil alumni pedigree) delivered to startups and mid-market companies that would otherwise lack access to Big 4-quality advisory.
The business model is project-based professional services with quote-based pricing (no public pricing or standard rate cards). Go-to-market is direct client engagement via email ([email protected]) and phone (02-598-7003), supplemented by a top-of-funnel digital presence on Facebook, Naver blog, and Instagram. The firm is independent and founder-operated with no disclosed institutional investors, parent company, or subsidiaries; revenue is not publicly disclosed and no funding rounds are on record. Customer segmentation is horizontal across two primary segments: startups (founding through exit) and established mid-to-large corporations with complex tax, restructuring, and M&A needs.
