About Z Enterprise

Z Enterprise Inc. is a South Korean financial technology company aiming to simplify complex financial and tax-related tasks for individuals and businesses. Founded in 2016 by CEO Lee Sung-bong, a certified public accountant, the company was born from his experience witnessing the struggles of small and medium-sized enterprises with tax and accounting matters, which were often a world away from the resources available to large corporations. Lee, who had a background in major accounting firms, taught himself to code by watching online university courses to build the company, initially named Emmental Inc., alongside a team of three other co-founders, including accountants and a developer.

The firm operates primarily through its flagship platform, 'BizNep,' which offers a suite of automated tax services. The client base ranges from individual freelancers and gig workers to small and medium-sized businesses across various sectors. Revenue is generated through a subscription-based model for its bookkeeping services and fees from its tax refund solutions. The company's key products include 'BizNep Refund,' a tax correction and refund service, and 'BizNep Care,' a more affordable, AI-driven tax bookkeeping and filing service. 'BizNep Refund' utilizes AI to review over 200 deduction and exemption items to find overpaid taxes for businesses, boasting an average refund of 9.6 million KRW for one in three business users. 'BizNep Care' automates much of the bookkeeping process, which the company states enhances productivity by over 80% and allows it to offer the service at a significantly lower cost. The platform also features 'BizNep SeNa,' an AI chatbot that provides real-time, expert-verified answers to questions about taxes, labor, and legal matters.

Z Enterprise has demonstrated significant growth and attracted substantial investment. In 2024, the company's revenue increased by 14% and its operating profit surged by 164% year-over-year. By June 2025, 'BizNep Refund' had managed over 900 billion KRW in tax refunds for 2.3 million business users since its launch. The company has secured a cumulative total of 35.5 billion KRW in funding through multiple rounds. A pivotal moment was a Series A investment from Naver and Naver Financial, marking their first-ever joint investment. More recently, in June 2025, Z Enterprise raised 26 billion KRW in a Series C round led by NH Investment & Securities and NH Venture Investment, with participation from other venture capital firms. These funds are earmarked for enhancing the BizNep platform, expanding services for corporate clients, and developing new business models based on big data.
