What OmniGrid does

OmniGrid (株式会社OmniGrid) is a Tokyo-based, privately held subsidiary of Tokyo Stock Exchange-listed InboundTech Co., Ltd., founded in September 2021 with 1-10 employees. The company historically operated a cloud communications portfolio including BizTAP (cloud PBX enabling smartphones to act as office extensions with number portability via NTT Hikari Denwa), BizTAP IVR (automated voice response and routing), SMS/email/FAX messaging, and the DESKWING enterprise rental server hosting service. As of July 1, 2025, OmniGrid divested its IVR and BizTAP businesses to NN Communications, with IVR termination scheduled for December 24, 2026, narrowing the residual business to BizTAP AI and DESKWING. BizTAP AI is an AI productivity platform layering consulting-led prompt engineering on third-party foundation models (OpenAI GPT-4/4o/5, GPT-Image-1, Whisper, o1, Anthropic Claude Opus 4/Sonnet 4) with proprietary speaker-separation transcription, RAG-based PDF/document search using Meta faiss, AI image generation, and a multilingual real-time voice agent (BizTAP AI Realtime). Revenue is generated primarily via monthly subscription pricing (~¥980/account for BizTAP, from ¥1,000/account for BizTAP AI, ¥10,000-20,000/month for DESKWING) plus usage-based call charges, distributed through a digital-first, SMB-focused go-to-market combining web self-service, online seminars, partner media referrals, and co-marketing with players such as blastmail. Customers are predominantly Japanese SMBs and mid-market businesses, with no large enterprise anchor customers disclosed.
