AIVANSAT

What AIVANSAT does

AIVANSAT (株式会社エイバンサット) is a privately held Japanese system consulting and custom software development firm headquartered in Osaka, founded in December 1989. The company operates four service lines: system consulting aligned to customer requirements, software commissioned (outsourced) development, technical support for implemented systems, and software sales. It is the designated Japanese consulting partner for SilverStream, a US-based Java Application Server, and one of the few firms in the Kansai region with hands-on SilverStream development experience, providing proposals, implementation, and aftercare for that platform.

Its technical stack centers on Java-based application server development using SilverStream, Oracle Database for data layer work, and PowerBuilder as the RAD tool, with project delivery spanning UNIX-to-PC environments. Engagements extend beyond SilverStream to industry-specific custom systems including cleaning-industry scheduling, food-company production and financial accounting, pharmaceutical package localization, ISP customer information systems, university groupware, manufacturer production and logistics management, and construction inventory systems. The customer roster disclosed on the corporate site includes Canon Inc., Canon Software Inc., Soran Corporation, TDS Inc., Taiyo Kogyo Corporation, Tsuzuki Electric Co., Japan Comsys Corporation, Japan Systemware Co., Fuji Xerox Information Systems, and Fujitsu Ten Information Systems, among others, indicating a mid-market Japanese enterprise focus across electronics, manufacturing, technology, and construction verticals.

AIVANSAT monetizes primarily through professional services fees for consulting and commissioned development, supplemented by one-time software license sales (notably SilverStream). It pursues direct engagement with enterprise clients rather than channel-based distribution, with all delivery originating from its single Osaka office in Kita-ku. The firm runs continuous new-graduate and mid-career hiring for Java-capable programmers and SEs, and emphasizes aftercare support as a core operating principle. The most recent verifiable corporate activity captured in the input is the website relaunch of August 2009, with no subsequent strategic moves, funding events, or product launches disclosed.

Recent moves4 records

Expansion highlights3 records

Broad incumbents

• NTT Data Group: Largest Japanese IT services incumbent offering full-lifecycle custom development, consulting, and systems integration across all industries. Overlaps with AIVANSAT's core enterprise custom-development offering as part of a much broader portfolio.
• Fujitsu Limited: Global Japanese-headquartered IT services and consulting giant offering custom development, system integration, and managed services. Fujitsu operates across an overlapping enterprise customer base in Japan, though it dwarfs AIVANSAT in scale and breadth.
• Accenture (Japan): Global consulting and IT services firm with significant Japan operations delivering custom software development and enterprise integration to blue-chip Japanese firms. An indirect peer of AIVANSAT operating at very different scale but on directly overlapping enterprise-custom engagements.
• Otsuka Corporation: Long-standing Japanese IT services and consulting provider focused on enterprise custom application development and integration. Shares the same enterprise mid-market focus on custom business systems as AIVANSAT but operates as a much larger, established incumbent.

Direct peers

• BIPROGY Inc. (formerly Nihon Unisys): Long-established Japanese systems integrator providing enterprise application development, integration, and consulting services. BIPROGY's full-lifecycle enterprise IT delivery model closely parallels AIVANSAT's custom development plus aftercare service, though at materially greater scale.
• Future Corporation: Tokyo-based Japanese IT consulting firm focused on systems development and consulting for financial, distribution, and manufacturing clients. Both firms target Japanese enterprise custom development with strong vertical reach, differing primarily in scale.
• JSOL Corporation: Japanese IT services firm delivering custom system development and consulting for financial institutions and manufacturers. Shares the same enterprise-focused custom-development, systems integration model as AIVANSAT, particularly around mission-critical legacy platforms.
• SCSK Corporation: Major Japanese IT services company providing custom system development, consulting, and outsourcing across enterprise clients. SCSK competes for the same enterprise custom-development mandates that AIVANSAT serves, although at substantially larger scale.
• TIS Inc. Major Japanese IT services and consulting firm with deep roots in custom software development and systems integration across enterprise customers. TIS is comparable to AIVANSAT as both deliver custom enterprise application work to Japanese corporations; TIS is significantly larger but operates in the same core market.
• NS Solutions Corporation: Japanese IT services firm delivering custom enterprise system development and consulting, with strong manufacturing and process-industry vertical depth. Similar service mix and customer profile to AIVANSAT.
