Jiayin Group is a Chinese fintech platform that connects individual borrowers with institutional lenders — banks, trust companies, consumer finance companies, and microcredit companies — without lending its own money. Jiayin's typical borrower is a young, urban, salaried individual who is creditworthy but underserved by traditional banks, seeking unsecured consumer loans generally under 12 months in duration. Borrowers apply through Jiayin's mobile app or website, where the platform handles identity verification, anti-fraud screening, and credit scoring automatically before routing qualified applicants to institutional partners for funding. Jiayin earns revenue primarily through loan facilitation fees charged to institutional partners, which now represent roughly 83-85% of total revenue. Jiayin also earns guarantee-related revenue by providing credit enhancement to institutional partners, though the company has deliberately reduced this stream as it carries lower margins and creates contingent balance sheet liabilities. The core business is asset-light, as Jiayin does not hold loan assets on its balance sheet. Key profitability drivers include facilitation volume, borrower acquisition costs (primarily digital marketing), and repeat borrower rates — in Q4 2025, repeat borrowers represented nearly 80% of facilitation volume. Beyond its core China business, Jiayin is growing a "technology empowerment" model where it embeds its platform within large internet platforms to connect their users with financial institution partners. Jiayin is also expanding into Indonesia and Mexico, applying its credit assessment technology to underserved consumer populations in those markets.
