mocomoco

mocomoco株式会社 (mocomoco inc.) is a Tokyo-based company founded in April 2024 that develops voice and language AI. Its product is mocoVoice (モコボイス), a speech recognition and transcription platform designed for use in operational environments rather than quiet offices. The company states that conventional transcription tools were built around desk-based PC use, while mocoVoice was designed from the outset for on-site conditions, addressing three stated problems: recognition accuracy under noise, handling of industry-specific terminology, and performance in offline (in-person) meetings.

The platform covers audio capture through downstream use: transcription with noise resistance, speaker separation and speaker-name estimation, automatic generation of meeting minutes and daily reports in customer-specified formats, Word/Excel/PDF output, Slack and email notification, permission and organisation management, translation across 99 languages, long-duration recording (including recordings exceeding 24 hours, subject to file size limits), and cross-organisation RAG search that links answers back to the original audio. The company describes this architecture as a "voice lakehouse." A medical model is described as co-developed with Hiroshima University Hospital for disease, drug and department names. On-premises deployment is offered as a discussion option, and recording hardware is lent to customers with advice on microphones and recording environments.

The underlying AI technology is attributed to a group of researchers from the Nara Institute of Science and Technology (NAIST). The company is led by representative director and CEO Koki Tanaka, is headquartered at Roppongi 7-20-19 Inada Building 302, Minato-ku, Tokyo, with a second office in Roppongi 6-chome, and reports paid-in capital of JPY 1 million.

Founding story

The company name mocomoco derives from a Japanese onomatopoeia evoking something that gently envelops the space between people. Its stated vision is to bring a new tool to the world that changes human history, framing AI as a successor to writing, the printing press and the internet; its mission, "realise what you intended," positions AI that adapts to human intent rather than requiring people to adapt to the tool through prompting, via models specialised by industry (medical, construction, finance).

Business model

B2B SaaS sale of the mocoVoice speech recognition platform, complemented by B2C/individual self-serve subscription. Corporate engagements are quote-based and bundled with implementation services: template/format design, recording hardware loans, roll-out design from a single department to company-wide, effect measurement and ongoing support. Industry-specific packages are offered for sales, medical administration, multi-site field management and long-duration on-site recording.

Subscription pricing. A 14-day free trial requires no card registration and includes unlimited transcription, all AI features, free loan of recording equipment and operational support. A small individual plan costs JPY 690 per month for up to 200 minutes of transcription with limited AI features and restricted cross-RAG search, no team sharing or permission management. Corporate plans are priced on quotation according to number of users and recording volume.

Traction

Customer-reported outcomes published by the company include: Hiroshima University Hospital reducing specialist-term correction work from five hours to under one hour (pediatric surgery terminology corrections cut to a quarter); Tokyo Isea Clinic producing minutes 10-20 minutes after meetings; Toyota Corolla Netz Gifu summarising 30-minute videos into roughly five minutes of reading; City Plus Holdings moving construction and civil-engineering meeting minutes from 2-3 hours of work to same-day completion; GMB where six of eight participants reported shorter internal-audit minute preparation; and Kyushu Sangyo Unyu cutting board-meeting minutes from 2-3 hours to about 15 minutes, roughly a 90% reduction. Sekisui House and Toyota Netz are cited as deployment examples.

Latest developments

In 2026 the company refreshed both the mocoVoice product logo (effective 1 April 2026) and its corporate logo (June 2026), and expanded exhibition activity to nursing-care (CareTEX Fukuoka '26) and general DX events, including AI Agent DXPO Tokyo '26 in August 2026. A startup platform profile lists the company at pre-Series A stage with up to 30 employees.
