Company profile
researched Sep 2026rubi labs株式会社 (RubiLabs株式会社, English name Rubi Labs Inc) is a Tokyo-based financial technology company headquartered at 18-10 Nihonbashi Koamicho, Chuo-ku, in the J Square Building. It develops technology for financial institutions covering AI-driven risk monitoring, digital onboarding and compliance, including AML/CTF (anti-money laundering / counter-terrorist financing) infrastructure and real-time risk detection, system integration and operational support for financial and public-sector organizations, and research and implementation of data pipeline and graph analytics techniques.
Its principal product is Lapis, described as risk analytics and AML/CTF intelligence. Lapis analyzes geopolitical and regulatory developments and other qualitative risk indicators to infer how risk may emerge, propagate and affect an institution, and it consolidates KYC data, detects anomalies and surfaces risk hidden in transaction data. The company positions Lapis around four workflows: transaction analysis (bringing external developments into the context of live transactions, covering counterparties, routes and cross-border activity), counterparty analysis, exposure monitoring, and scenario analysis. Coverage themes include geopolitical risk, regulatory shifts, economic security and corporate events. A second offering, FABRIC, covers data infrastructure and pipeline construction.
The company was established on 18 October 2022 and is identified as a university-originated startup linked to Waseda University. It reports roughly 10 or fewer employees, and its corporate registry entry records a Tokyo establishment with two insured employees.
Business model
B2B software and services sold to institutions, combining a product (Lapis, with FABRIC for data infrastructure and pipeline construction) with system integration and operational support for financial institutions and public-sector bodies.
Traction
Headcount of approximately 10 or fewer as of September 2026, with two insured employees recorded at its Tokyo office. The company held no registered patents, designs or trademarks and no recorded subsidies, public procurement or awards in the government business registry as of August 2026.
