1. Introduction
Japan’s corporate landscape is at a turning point. Pressures from demographic changes, evolving regulations, and global competition are pushing enterprises to rethink how they manage operations. Back-office functions—finance, tax, procurement, and HR—are often burdened by manual processes and legacy systems.
Enter LayerX, a Tokyo-based AI SaaS startup that has just secured a $100 million Series B funding round, one of the largest ever for a Japanese company at this stage. With strong investor backing and a rapidly growing customer base, LayerX is positioning itself as a key player in enterprise automation.
2. The Growing Need for Automation in Japan
Aging demographics and labor shortages
Japan’s shrinking workforce is creating structural challenges for businesses. As labor availability declines, companies must look to automation to maintain productivity and efficiency.
Regulatory shifts fueling digitalization
The 2023 implementation of e-invoicing added urgency for companies to modernize their accounting and compliance systems. Firms that fail to adapt risk higher costs and compliance burdens.
The digital transformation challenge
Despite these pressures, only 16% of digital transformations in Japan succeed—and the rate falls to just 4–11% in traditional industries. Barriers include weak leadership commitment, rigid corporate cultures, and a shortage of digital talent.
3. LayerX: Pioneering Back-Office Automation
Founded in 2018 by Yoshinori Fukushima, a serial entrepreneur with a background in machine learning at the University of Tokyo, LayerX began with blockchain and digital transformation projects before pivoting to SaaS.
The company’s insight came from identifying a major bottleneck in Japanese enterprises: paper-based invoice processing. This pain point gave birth to Bakuraku, an AI-driven platform that now powers workflows for more than 15,000 companies.
Core product offerings
Bakuraku Suite: Covers expense management, invoice processing, corporate card operations, attendance, receivables, and e-ledger compliance.
Alterna: A retail digital securities platform developed with Mitsui & Co.
Ai Workforce: A generative AI solution that streamlines enterprise workflows and integrates with corporate data.
4. The $100 Million Series B Funding Round
Led by Technology Cross Ventures (TCV)—its first investment in a Japanese startup—this round also attracted MUFG Bank, Mitsubishi UFJ Innovation Partners, JAFCO Group, Keyrock Capital, Coreline Venture, and JP Investment.
This brings LayerX’s total funding to $192.2 million, cementing its reputation as one of the fastest-growing SaaS companies in Japan.
Growth milestones and customer traction
Customer base: Expanded from 10,000 in February 2024 to 15,000 by April 2025.
Headcount: Grew from 220 employees in late 2023 to around 430 in mid-2025.
Revenue trajectory: On track to hit $68M (¥10 billion) faster than any SaaS company in Japanese history.
5. How LayerX Differentiates Itself
AI-driven user experience
Bakuraku integrates automation features such as auto-entry and document splitting, continuously enhancing usability. LayerX also invests heavily in AI agents and AI-enabled BPO, offering enterprises a scalable, intelligent alternative to manual workflows.
Competitive landscape
Domestically, LayerX competes with Money Forward, freee, and Rakuraku Seisan. Globally, it faces players like SAP Concur, Rippling, Brex, Ramp, Spendesk, and Airbase. In the AI Workforce arena, its rivals include Harvey.
What sets LayerX apart is its comprehensive, AI-first approach and a powerhouse team of experts, including over 12 former CTOs and a Kaggle Grandmaster.
6. Scaling Ambitions: From Japan to Global SaaS Leadership
LayerX’s goals are ambitious:
Achieve $680M (¥100 billion) in ARR by 2030, with half driven by AI agent services.
Expand headcount to 1,000 employees by 2028.
Build on partnerships with industry giants such as Mitsui & Co. and MUFG Bank.
The company is also pursuing a T2D3 growth benchmark—a rare achievement in SaaS—well ahead of schedule.
7. What This Means for Enterprises and the Future of Work
For businesses, LayerX represents more than a technology solution. It’s a pathway to:
Reducing operational bottlenecks
Ensuring compliance with evolving regulations
Enhancing productivity in a shrinking labor market
The rise of AI-powered automation signals a future where enterprises can focus more on strategic initiatives rather than repetitive tasks.
