LayerX is a Tokyo-based AI SaaS company focused on automating the paper-heavy corporate back-office workflows that are common in Japanese enterprises. Founded in 2018, the company applies large language models to extract data from receipts, invoices, contracts, and Japanese-language forms, then routes approvals through native integrations with enterprise systems, reducing manual processing across finance and administrative teams.
Its flagship platform, Bakuraku, provides an integrated suite for expense management, invoice processing, and corporate card operations. The company reports that Bakuraku is used by more than 15,000 Japanese companies, having passed 10,000 customers in early 2024 and continuing to grow through 2025, with headcount roughly doubling to around 430 employees over the same period.
LayerX's approach is tailored to the specifics of the Japanese market, including local document formats, approval norms, and integrations with domestic financial institutions. This localization is a key differentiator versus global expense-management vendors and aligns the product with the digital-transformation needs of Japanese corporations modernizing legacy back-office processes.
In September 2025, LayerX raised a $100 million Series B round led by TCV, described as the firm's first investment in a Japanese startup, with participation from MUFG Bank, Mitsubishi UFJ Innovation Partners, JAFCO Group, and others. The round brought total funding to roughly $192 million across four rounds and was among the largest Series B rounds for a Japanese startup of its age. The company has said it will invest in expanding AI capabilities and pursuing international markets.
Organizations evaluating LayerX should note that the product is primarily designed for the Japanese market and Japanese-language workflows; companies outside Japan or those without Japanese back-office processes should confirm fit and any international roadmap before adopting.
