TESSERA

What TESSERA does

TESSERA (株式会社テセラ) is a privately held Japanese business process outsourcing (BPO) company founded in April 2013 and headquartered in Tokyo's Koto Ward (Ariake), with a registered business correspondence address in Yokohama's Minatomirai district. The company employs 19 staff as of its most recent company profile and is led by Representative Director Terashima Yasunori (寺島 靖典). Its service portfolio centers on outsourced support functions for large Japanese telecommunications carriers, internet service providers, and related infrastructure firms, including back-office work (Microsoft Office-based documentation, data analysis), construction site assistance and progress management for telecom build-outs, and customer-facing scheduling and inquiry handling for ISPs. Beyond its core telecom/ISP BPO work, Tessera operates sales agency (取次) services for the U-NEXT video streaming platform (since April 2014) and handles broadband service distribution (since April 2018). More recently, the company has added facilities maintenance capabilities, including electrical cubicle cleaning (since December 2022) and a subcontracted maintenance role at the U.S. Coast Guard Training Center Yorktown in Virginia via Brevard Achievement Center Enterprises (announced January 2026).

The underlying "technology" is largely people- and process-based rather than software-based: Microsoft Office for document and data work, manual scheduling coordination, on-site construction support crews, and customer service desks. There are no disclosed proprietary software products, APIs, or platform architecture. Revenue is generated through professional services contracts with enterprise clients, with pricing not publicly disclosed and offered on a per-engagement basis; recruits are hired on contract terms at a base salary of 195,000 JPY per month with potential conversion to regular employment. Go-to-market is direct enterprise sales with no channel partner or reseller network, supported by a Japanese-language corporate website and direct recruitment activity. The company has relocated offices multiple times in line with growth (Shinagawa 2013 → Nihonbashi 2013 → Minatomirai 2017 → Ariake 2019), but has no disclosed external funding, investors, or parent company, and ownership structure is not public.

The customer base is concentrated in a small number of large Japanese enterprise accounts plus the U.S. defense subcontract. The company carries no AI/ML capability, no patents or trademarks, no certifications, no API products, and no awards or third-party recognition, which together signal a small, labor-intensive BPO operation whose defensibility rests on client relationships rather than technology differentiation.

• Concentrix Corporation: Global customer experience and BPO incumbent serving large telecom and technology clients with end-user support and back-office services; broader in scope and global in reach, but operates in the same customer service / back-office category Tessera addresses.
• Teleperformance SE: World's largest contact-center and BPO operator with significant telecom vertical exposure, providing customer service, technical support, and back-office solutions that situate it as the global incumbent reference point for Tessera's service category.
