LayerX, an AI SaaS startup that enables businesses to cut back-office workload, has raised $100 million in a Series B round led by TCV, marking the U.S. fund’s first investment in a Japanese startup. The startup’s key offerings include Bakuraku, a platform that automates corporate spending workflows, covering expense management, invoice processing, and corporate card operations — for more than 15,000 companies; Alterna, a retail digital securities investment platform developed in partnership with Mitsui & Co.; and Ai Workforce, a generative AI solution designed to streamline workflows and harness enterprise data. Bakuraku differentiates itself with an AI-driven user experience. The company continuously upgrades automation features like “auto-entry and document splitting,” while also investing in AI agents and AI-enabled business processing outsourcing (BPO). Its team includes “more than 12 former CTOs and a Kaggle Grandmaster.” Bakuraku offers a comprehensive, integrated platform covering “expense management, invoice processing, corporate cards, workflows, e-ledger compliance, attendance, and receivables — all in one solution.”
