What AI inside does

AI inside Inc. is a Tokyo-headquartered AI technology company that has built a vertically integrated stack spanning proprietary Japanese-language large language models (PolySphere 1-4), AI-OCR engines, edge computing hardware (AI inside Cube), an LLM-native integration platform (Leapnet), and business applications (DX Suite). The company primarily serves Japanese enterprises, government agencies, and local municipalities that need to automate high-volume, document-heavy back-office processes; as of March 2026, its flagship product DX Suite has been deployed at over 3,000 organizations representing more than 70,000 users, with cumulative usage of more than 10 billion document readings. The customer base spans financial services (77 Bank, Sompo Japan, MS Plus One, Sumitomo Mitsui Trust Net Bank), insurance, construction (Kajima Corporation, Hashimoto Holdings), healthcare (Nagasaki Prefecture medical institutions), accounting (Morita Tax Accounting), retail (MAYB3), and legal services (Nakamoto & Associates).

The technical foundation rests on PolySphere, a family of proprietary Japanese-specialized LLMs trained for document understanding. PolySphere-4, the latest version, powers DX Suite's claimed 99.6% OCR reading accuracy, while PolySphere-1, -2, and -3 are tuned for narrower use cases including custom fine-tuning via the Customized SLM option. The product portfolio comprises three core offerings: DX Suite (cloud or on-premise AI-OCR and AI agent for data entry), AI inside Cube (an edge computing appliance in Lite, standard, Pro, and Pro 4U/4U+ form factors), and Leapnet (a 2026 LLM-native platform for building AI agents from internal data using multimodal RAG). Additional capabilities include Critic Intelligence (proprietary error detection), Learning Center Vision and Forecast (no-code AI platforms), and a research-grade Full-Duplex voice dialogue model developed under the GENIAC Phase 3 government program. AI inside Cube Atlas 192x, introduced in mid-2026, is the first hardware capable of running all Leapnet functions on-premises and functions as a node in the Sovereign Grid distributed AI inference network.

AI inside generates revenue through four streams: SaaS subscriptions (DX Suite, Leapnet at 2 yen per 1,000 tokens), hardware sales and subscriptions (AI inside Cube and Cube Atlas), professional services through the InsideX consulting team, and usage-based API/token consumption for AI agent inference. Pricing is generally not publicly disclosed. The company operates an enterprise field sales motion with a strong partner-first distribution strategy; approximately 90% of contracts are closed through channel partners, including distributor Daiwa Information System (with a network of approximately 19,000 partner companies) and OEM relationships with NTT East, NTT West, and NTT Data. The company is publicly listed on the Tokyo Stock Exchange Growth Market (ticker 4488) since December 2019, has 130 regular employees as of March 2026, and reported 9.1% year-over-year sales growth and a 173% net profit increase in the first half of FY2025.
