Ringbull Co., Ltd. has raised ¥300 million in a new funding round led by DG Daiwa Ventures, with participation from investors including Headline Asia and Gazelle Capital. The company says the money will mainly go toward expanding its global e-commerce platform and developing its AI system called ‘Tsuro-san.’
The bigger problem Ringbull is chasing is pretty clear. Selling globally still feels built for large corporations. Smaller and mid-sized brands get buried under logistics, language support, payments, compliance rules, customer support, and cross-border operations.
Ringbull’s platform, ‘Lingble Link,’ already helps brands manage those moving parts. Now the company wants AI to handle more of the operational and decision-making layer too.

That is where ‘Tsuro-san’ comes in. The AI system is designed to organize sales and product data, then support brands with overseas expansion decisions and operations. The beta version will start rolling out to existing customers from May 2026.
The company is also pushing expansion into markets like South Korea next.
